MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for PLATFORM and FULL STACK who can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Rapid deployment and iteration of experimental software changes across firmware, control software and UI

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.
