Profitmind | Web Scraping Junior Developer | Remote or Pittsburgh | $90-110k | Full-time | https://www.profitmind.com/

At Profitmind, we're building massive-scale ecommerce datasets to use in AI training/inference, and we need a junior engineer to help develop the scraping infrastructure for product data. You'll be reverse-engineering undocumented APIs, handling anti-bot systems, and dealing with edge cases like pagination limits, rate limiting, and sites that change their protection schemes without warning. It's fun work! The technical side involves analyzing a site's network requests, deobfuscating and reading obfuscated javascript, and implementing simple HTTP request scraping to full browser automation. You'll also work on the infrastructure layer: state management for resumable scrapes, deduplicating products, data integrity, and monitoring systems to detect when sites change.

The work you'll be doing is in the hot path of our company, so the systems you will build need to be performant and maintainable. You should have solid Python skills and experience scraping ecommerce websites and APIs. You should also like the slightly-obsessive investigative nature of the work.

If you worked in scraping or botting in the past, please hit me up!

I’m not sure if this is the right place to post this, but to everyone commenting here saying they’re hiring and asking people to send their CVs —

please have the basic decency to send a simple acknowledgement or revert after receiving them.

This has happened repeatedly over the past few months after sending dozens of emails from these threads, sometimes 10+ at a time. Not getting even a basic response feels extremely disheartening.

I know it’s a tough time for everyone searching for a job, and we all understand if things are slow —

but a small confirmation like “Received, we’ll check” or “Not hiring anymore” takes 5 seconds and makes a world of difference.

Let’s be kinder to each other. It’s been a very hard year

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/

Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M (https://zed.dev/blog/sequoia-backs-zed) to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Vibrant (https://www.vibrantpractice.com) | Founding Engineer | Full-Time | SF (hybrid) or Remote with frequent travel to SF

We're building Cursor for doctors. At Vibrant, we've picked the expensive, high-touch, data-heavy subspecialties of functional, integrative, and longevity medicine, and we've created AI agents that reduce hours of clinical work to minutes.

We're a world-class team of health tech founders, AI builders, and clinicians from Meta, Stride Health, Peloton, and Hinge Health. In just five months, we've built notetaking/scribing, Clinical Decision Support, and some of the integrations a clinician needs to run their practice with Vibrant as their AI Operating System.

In the words of doctors using our product already in production: "I have goosebumps, this is really incredible. Very accurate." "Seeing the patient overview AI-generated summary come to life after placing a couple notes is AMAZING. I'm losing it over here."

Our stack: Typescript, React, NextJS, React Native, Expo, AI SDK, custom AI agents, RAG, tools, and agentic workflows.

It's still early days for us, and we're looking for folks who ship fast and are curious and resourceful. If that's you, shoot me an email at pedro [at] vibrantpractice.com or just book an intro with me: https://book.vimcal.com/p/pedro/quick-chat

Trunk | https://trunk.io

Marketing Lead (Developers) - Remote friendly | Forward Deployed Engineer- Software Engineer II | DevRel Engineer - San Francisco| Staff Full Stack Engineer - San Francisco | Sr Full Stack Engineer - San Francisco

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)

At Goblins, we're building America's favorite teacher, starting with K-12 math. We're live in thousands of classrooms for in-class assignments, extra practice, and homework. Students work on a whiteboard while our models analyze their work in real time and nudge them with questions that make them think. Teachers get instant visibility into how the class is doing, who needs help, and what to assign next.

We just raised our seed round and are backed by the Gates Foundation, giving us the ability to build something transformative in education.

Here's what you might work on:

- Create shareable "aha moment" videos from real student sessions.

Turn anonymized whiteboard work and Goblin–student dialogues into short videos or interactive replays that highlight the value of Goblins. Automatically identify the best moments, strip out sensitive data, and produce artifacts that teachers, parents, and districts want to watch and share.

- Rewrite our diffusion transformer real-time avatar stack.

Our Goblin avatars are already in production. Improve audio–motion sync, temporal coherence, and expressiveness, while cutting latency and cost so they run smoothly at 100k+ student scale.

- Extend continuous diagnostics to high-stakes like the SAT and ACT.

We track mastery against state standards with our spin on IRT. Extend this to SAT/ACT-style exams: infer score distributions from behavior, validate on real data, and compute minimal targeted practice that reliably moves predicted scores.

- Design uncheatable problem formats.

Generative AI can solve most traditional math problems and show fake work. Build formats where copying is harder than thinking: dynamic graphs, constructive proofs, counterexample generation, debugging flawed solutions, multi-step conceptual checks. Make them auto-gradable, resistant to copy-paste, and stable at scale.

- Build real-time instructional agents.

Detect underlying student misconceptions from their work and have an agent "drop in" only when needed. It should generate short, visual, 3blue1brown-style explanations tailored to the specific misunderstanding, and create diagrams, animations, and interactive examples that adapt as the student responds.

The role is based in our Williamsburg, Brooklyn office in NYC (on-site only). You'll join our tight-knit founding engineering team of 3—myself (the CTO) and two founding engineers with collective experience from Stanford, Stripe, Amazon, and X1.

As our third founding engineer, you'll have full ownership of critical projects and ship production systems that impact thousands of students and teachers in real classrooms within your first few weeks.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading collector of ocean-related in situ data via uncrewed vehicle, above and below the sea surface. We work with navies across the world to deliver insights about waterways, contribute to safety of life at sea, and mitigate illegal fishing and trafficking. Additionally, we work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, or counting biomass to establish fishing quotas.

Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just announced a large partnership with Lockheed Martin[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand and secure our planet.

Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

You can see a list of open positions on our career page: https://www.saildrone.com/careers

Hey HN, I’m the founder of Vect AI. We built the world’s first all-in-one autonomous command center for high-growth marketing. Most AI tools are just wrappers that generate text. We built a system that understands strategy. The Problem: Marketing is fragmented. You have one tool for copy, one for images, and spreadsheets for planning. It’s manual and disconnected. The Solution: Vect AI is an autonomous growth engine. You define a Goal (e.g., "Launch a B2B SaaS product"), and our AI Agents: Analyze real-time market signals and competitor angles. Strategize a multi-phase campaign (Tease, Launch, Sustain). Execute the assets: Social posts, emails, ad creative, and viral video scripts. Under the hood: We’re using a multi-agent architecture powered by Google's Gemini Pro models to handle complex reasoning chains. We also built a "Resonance Engine" that simulates audience psychology to audit your content before you publish. It’s free to try (no credit card required). I’d love your feedback on the agent orchestration. Link: https://vect.pro

Vestwell | Senior Software Engineer | HYBRID - NYC; Austin; King of Prussia, PA | https://www.vestwell.com/careers/7510610003 | $145K - $160K base + bonus & equity

I'm the hiring manager for this role. Please see the job description for details, but I'm looking for someone who is, or is able to become, proficient in backend development for a public nest.js API suite using TypeScript. We don't have any hard requirements like a CS degree or prior nest.js experience, but candidates do have to complete a TypeScript coding challenge. It's a real-world problem, no leetcode. In total, our interview process is only 3 rounds, and we move pretty quickly. We also want someone who has systems design experience and good technical leadership skills. You also have to be self-motivated.

The hiring process: quick intro call, 2 technical interviews, & an onsite interview, followed by offer!

We've recently tripled our headcount here in NY & do not plan on slowing down anytime soon! If you are someone who wants to work on meaningful problems, values clean code and thoughtful systems, & loves building tools for other engineers, we'd love to chat with you!

You can apply directly on our careers page(https://graphite.dev/careers#positions) or email sam@graphite.dev with the subject title: "Thank you for stacking with us) with a copy of your CV.

Mulligan Post, Inc - On-Site near Millbrae BART/CalTrain Station in Burlingame - $60-120/hour Contract - Mechanical Design Engineer / Mechatronics / Industrial Automation.

Software hacker seeking hardware hacker to make custom robots for Magic: The Gathering automated storage and retrieval system to power an online e-commerce store (think CardKingdom competitor or eventual TCGPlayer competitor.) In terms of scale, the eventual target is >100k different _skus_, million items in inventory, tens of thousands picks per day. The industry is large; eBay bought TCGPlayer for $300M about 3 years ago.

I am looking for a mechanical/electrical/hardware generalist to complement my software expertise. Someone who knows how to integrate off the shelf parts into custom automation to solve problems. If fast iterations, direct connection with the project in use, autonomy and minimal bullshit overhead appeals to you then this could be a great fit. You are: someone who makes stuff and solves problems, is a clear communicator and fast study. You know how to challenge a requirement, source an off-the-shelf-part or design custom manufacturable part and when to do each. I don't really care where or when or what your degree is in if you have demonstrated driving things to completion and we vibe well enough.

We will use OnShape (license/seat will be provided) for collaboration and document management reasons. Much of what we need to build is integrating FUYU linear rails, Clearpath motors, pneumatics with some custom Send Cut Send / Xometry parts, 8020 frames, etc.

Pros: Small team / minimal overhead and wide scope. Clear guidance on what to build. Flexible-ish schedule (core hours 9-5 in office, flexibility for school breaks, etc.) Real problem with established market.

While I'm primarily looking for a contractor for now, I am open to the possibility of bringing the right person on full-time with equity if they are interested and invested in the space, but that is not a requirement and it probably makes sense to establish that after working together for a bit.

No recruiters or third parties, not able to sponsor at this time. Compensation dependent on experience.

Hiring process: resume/project review, vc chat < 1 hour, then paid 1-day work trial where we see if we fit.

If you're interested, send me an email - hiring@mulliganpost.com

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

-- Junior Software Engineer - Remote (Global), Full-Time

We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.

I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.

The coding interview question involves a collection of points (places) on a 2D grid. Places and Queries against those places are listed in sequential order in a commands.txt file in a colon-seperated format. A query is a circle with a center point and radius, along with a collection of 0-N expected places contained within it.

    Place - id, x, y
    Query - id, x, y, radius, expected return values (comma-separated)

The task is to persist the places data in sequence and ensure queries return the set of expected places out of all places that have been seen so far. This is a basic geometry problem - if the euclidian distance (x^2 + y^2 = r^2) between any place and the circle's center is less than the radius, the place is contained in the circle. You should anticipate thinking of ways to optimize once the dataset gets very big if you successfully complete the specific task within the allotted time.

    # commmands.txt example

    place-1:34.7:94.5
    place-2:54.1:5.2
    query-1:15.2:17.1:5.0:                  # no results expected
    place-3:44.9:27.4
    query-2:35.0:94.0:2.0:place-1           # one result expected

FUTO | Austin, TX | On-site / Remote | Full Time

FUTO is an organization dedicated to developing, both through in-house engineering and investment, technologies that frustrate centralization and industry consolidation. Our work consists of a combination of in-house engineering projects, targeted investments, generous grants, and multi-media public education efforts. Our principles are here: https://futo.org/about/what-is-futo/

Machine Learning Engineer - FUTO Keyboard

FUTO Keyboard is a privacy-first software keyboard for Android. Every prediction inference routine runs entirely on-device; no user data can ever leave the device. We support over 150 keyboard layouts and languages, and over 700 layout + language combinations (not all of them include dictionary or predictions)

Swipe typing is an important part of the mobile typing experience for many. Applying machine learning here poses a unique challenge due to the requirement of needing to support so many layouts and languages, as well as user-added personal dictionary words (or even layout customizations!), with limited data. We have previously collected and publicly released a US English QWERTY dataset: https://huggingface.co/datasets/futo-org/swipe.futo.org/

We are looking for a machine-learning researcher or engineer to work through these challenges and help us improve the swipe typing experience in FUTO Keyboard.

Pinetree is building the best onchain platform for video creators: a crypto-native alternative to ad-driven video platforms that gives creators real ownership over distribution, monetization, and their content. We’re looking for someone highly autonomous who brings solutions to complex problems and wants meaningful product and company ownership.

You should have experience writing and deploying production software in TypeScript, ideally on a small (<50 person) team or other startup environment, and be comfortable working across the stack (React / React Native / Next.js, Node, Postgres). Crypto or social product experience is a plus.

Stack: TypeScript, React, React Native, Next.js, Node, Postgres

Shorebird | Mid-Senior Systems/Runtime (C++) Engineer| REMOTE (North America) | Full-time | $160-230k + equity + benefits | https://shorebird.dev

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability early 2026.

As part of our over-the-air updates “code push” product, we’ve built a custom compiler and runtime for the Dart language, primarily written by me (founder/CEO). Now that we have thousands of customers, I have many other responsibilities and need to bring on a fulltime engineer (you!) to take over primary responsibility for all of our C++ code (Dart & Flutter forks, custom runtime, compiler, etc.) and evolve it further than I could alone. Together, you and I will add obfuscation, improve our interpreter, possibly re-write method dispatch, etc. You don’t need to be a compiler/runtime expert. You do need to be capable of working on large open source projects, be comfortable with C++, want to work at a startup, work well independently (we’re remote) and want to learn and work on lots of different areas of code.

If you’ve contributed at least a little to WebKit, Godot, Firefox, or any other large open source project, are compiler/runtime curious, and want to work at a growing startup, you will likely find this role extremely rewarding.

We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, React, Dart, C++, Rust. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird

Source (https://source.network)| USA/Canada: REMOTE | Full-Time | https://careers.source.network
