Don't rely on hierarchy. Earn others' trust as you would when you are an equal. Don't expect deference just because of your position. Although hierarchical decision making may be more efficient, it's an unnatural system and anti-social and easily generates animosity. You'd do better to empower your peers instead, and show them you are able to listen to them as well. Just like you would with friends.
wiseowise•50m ago
Big pile of horse shit, every word.

Wasted years in previous company under narcissistic manager with the same mindset. The guy had official senior lead title and was calling the shots. When ther team became too big, he assigned most senior people as “leads” without the official title. You had to perform as a team lead in an environment where your decisions do not have authoritative power, so every small task became negotiation with every member regardless of their seniority. Also no salary bump either. The “teams” quickly collapsed and they hired official team leads from there, with a real authority.

> After that incident, I created an incident review document and suggested a small review of the tasks that should be prioritized to prevent it from happening again. I got carried away and created an initial presentation for the other backend Chapter Leads with a backend strategy. I do not remember it perfectly, but it included hexagonal architecture, a testing pyramid with contract tests to avoid breaking APIs used by mobile apps, and more

Definitely got carried away. When coming to a new org, it's always good to learn the ropes a bit before fatiguing the team with more work, processes, and burdens.

tormeh•2h ago
> hexagonal architecture

God help me. Was on a project where this was used to justify so much extra boilerplate. Every class had an interface, and then we used dependency injection to supply the class to something expecting that interface. Actually, it was in Rust, so there were no classes, but that didn't stop us. Absolute waste of time.

littlecranky67•1h ago
Sounds like a regular setup, at least this is very common in modern C#/.NET when you implement REST services. Nothing to do with Hexagonal Architecture, just inversion of control. There is a very thin DI container baked into ASP.NET and the pipeline. Do you have to use that? No, but it gets complicated very quickly if you don't. So any project that is more than a tech demo/eval uses DI. In other languages/frameworks (i.e. Typescript+NodeJS) this is not very common for some reason.
tormeh•1h ago
I don't know much about C#, but in Rust this is very much not the norm. In fact, there are technical limitations associated with async traits. This sometimes allowed us a reprieve from the madness, but only sometimes. I guess you can write enterprise Java in any language.

The entire idea was to make it easier to mock components and therefore easier to test code, however all the code connecting the components became untestable, so we were back to square one, struggling to meet our test coverage quota because of the massive amounts of boilerplate.

littlecranky67•1h ago
What is the default way in Rust to write REST endpoints and have the REST endpoint use/create handles to your database transaction that is bound in scope to the underlying HTTP request? (i.e. transaction lifetime and commit/rollback is linked to the HTTP request succeeding)
tormeh•2m ago
Often each API route will have its own handler function. That function will - usually through many layers of indirection and abstraction - launch queries towards your database.
zelphirkalt•1h ago
The easiest thing to test will always be pure functions. Many people don't realize this, and how clean it can make your tests look. Provide input, get return value, assert/check it. Sure, at the end of the day you have some IO somewhere. But that will usually be a smaller part of the code base. Codebases that make testing more difficult than that, are making it unnecessarily complicated. Sometimes you depend on some library that forces you or heavily nudges you into another style, that can happen. But what one wants to avoid is a codebase, where one has to know to mock 5 other things because of their side effects.
tormeh•5m ago
Exactly. Divide the code in impure and pure functions. The pure functions can be easily unit tested. The impure ones can often be integration tested. The rest you'll just have to live with. For tests spanning larger chunks of your code base it might be worth it to mock impure code. Never mock pure code - that's madness.
wiseowise•58m ago
How do you fake implementation without using interfaces/abstract classes?
wwosik•1h ago
DI yes. All the crap under the name of "Clean" Architecture - no.
humanfromearth9•34m ago
Interfaces are only necessary to properly abstract away from implementation details that have different change driver assignments. Else it's overkill and arbitrary. This doesn't invalidate hexagonal architecture, it just provides the actual good guideline to know if abstractions and information hiding are necessary.

Check the Independent Variation Principle paper for more info: https://doi.org/10.5281/zenodo.17677316

The IVP provides two directives that help evaluating objectively design options, based on actual business decisional authority structure, not some guy's intuition. With the insights of the IVP, you'll be able to decide effectively.

The paper is long, but you can skip to the parts that you find interesting

This is probably the single, most important advice for any new person joining a company in a (technical) leadership position. There are going to be missing things in any org, and bad mistakes, and people needing to learn new things. But also there are going to be tons of decisions that make "no sense" on first look that do have a reason behind, and to fix that "root cause" you probably need a 3 years plan and buy-in from C-level. So, trust the team you are going to lead.

If nobody is listening to you then you aren't a tech lead, just saying
OutOfHere•5m ago
This. If the lead has no power to suspend people without pay, or to fire people, then he is not a lead. It's okay for this power to be indirect so long as it can be wielded when necessary.
omgJustTest•2h ago
"I'm a tech lead, nobody listens"...

1. Listen to what other people say and what they think the problem is, or what the problem "says".

2. Think, ask questions to clarify and repeat step 1. Is the problem actually technical? branch a. otherwise branch b.

a. have you considered the problem is mostly not technical? then proceed to branch b.

b. what miscommunications are keeping the solution from being implemented?

3. Change minds with the words that are convincing to others. Dont be so convinced of your solution that you wouldnt take a better one, return to step 1 unless the problem is "solved"

My blog would be uncompellingly short.

At previous corporation, the tech lead simply recommended for sackings a developer who was questioning his approach. Once he got sacked, everyone listened...

...and then most of best skilled people left in the following weeks.

You have to build / earn your influence. People listen to you after you have a reputation of being "right" enough times, and by being likeable. Abusing hierarchy isn't it.

That depends on the cultural / politics health of the group. The likeable right guy can end up stomped because he's a threat to the wrong dubious people. Seen this first hand in some companies.

Edit: accidentally hit update instead of scrolling…

One thing missing from the article that I don’t think has been mentioned is confidence and setting expectations. I’ve found if I expect certain results and convey confidence, people are more likely to follow your lead, or at least listen to you. Don’t act like a know it all, and be sure to encourage and question others so the environment is collaborative (solve problems as a group; don’t be a hero). But set expectations.

Also, I don’t think you mean “intimacy.” Do you mean “empathy?”

socketcluster•2h ago
I've been tech lead at different companies. Every time I switched companies, I started out as senior dev and got promoted into the team lead role again; each time with full support of my team.

I don't look or act like a leader and this has been a hurdle for me. But what typically happens anyway is; within a few months, my code ends up being a core part of the project; my modules become heavily depended upon and somehow I end up maintaining all the config files and guiding architecture decisions. One of my team members joked that I "conquered everyone's code." I probably write fewer lines of code than everyone else but somehow those lines end up heavily used. So then I basically just ask the big boss for a team lead position.

master-lincoln•1h ago
I don't understand why that is a logical progression. Writing good code and leading a team needs vastly different skill-sets in my eyes.
antonymoose•1h ago
I would argue that the two skills are necessary but not sufficient. If you’re lacking in the core skill, what exactly are you leading? If you’re a great coder and socially inept, good luck leading.
zelphirkalt•1h ago
On the other hand, if you want to lead a bunch of engineers, you should know their work very well, otherwise you will have unrealistic ideas about what can get done and how they should do it.
Braxton1980•1h ago
Being a good leader is partially out of your control. The people under you need to respect you as a leader. Working with them and showing your technical skills can gain their respect
skywhopper•1h ago
Honestly I’ve seen plenty of folks get promoted to “team lead” because they aren’t as productive with the actual coding. Someone needs to focus on the non-technical project tasks, so the boss picks the least productive team member to move to that role. Calling it a “team lead” makes it more appealing than calling it “worst coder”.
maddmann•35m ago

I am assuming that the point is, when you start in your team's shoes and then get promoted to team lead, your team knows you are capable and that you have well reasoned opinions. Hopefully.
AdrianB1•1h ago
As the other commenters stated, it is not clear what is the point. Writing good code and being a tech leader are very different positions with very different technical skills. I was a tech lead in a few cases (different companies or different departments of a very large company) and I was not the top developer there, my job was not to be one. I worked with developers that were much better than me that were not a good fit for a tech leader.
benchly•1h ago
While I am not a software developer, it sounds like our career paths have had the same trajectory, and I'm wondering what the common factor is across industries.

I work in automation (mostly) as a lead tech and professional troubleshooter because I am familiar with a wide and varied amount of automation technologies. I've met plenty of people over the years who have much more advanced skills than myself, but never go beyond doing more than parts swapping on a workbench, which leaves me scratching my head.

Over the last few years, I have listened carefully to what people around me say about my work, and while it is good gas for the ego, I have notice that's not the likely reason I get promoted so quickly. While I can walk into a problem and know how to apply different processes to figure out what to do almost reflexively at this point, the real focus seems to be that I take ownership of the process.

Bit of a buzzphrase, "ownership of the process," but the short explanation is that a little planning, accountability, resourcefulness and communication seems to get you a lot further than just knowing what to do in any given situation. Employers like that because they now have department manager they can rely on, and team members like that because someone else is taking responsibility so they don't have to.

You're good at code, obviously, but if you zoom out on your work a bit, are you also bringing a bit of accountable authority to the table? That may be the real reason why you move up so quickly, or at least something that greases the gears so that can happen faster for you than, say, an equally skilled colleague.

DoctorOW•2h ago
> Note: this article is a translation from the original “Soy Tech Lead y no me hacen caso. ¿Qué hago?”, in Spanish.

I wonder if "tech lead" coincidentally are two words that are the same in Spanish as English, or if this is considered a technical phrase.

ioma8•1h ago
Totally not the same. Its used as technical phrase. In europe we have many languages, but in most of them we use the term Tech lead as phrase.
torginus•2h ago
I'm sorry, but this reads like your standard Euro company shitshow - code being a disorganized mess, nobody having a deep understanding of either the business flows, or how the code works. Management consisting of feelgood people who are incapable of making decisions, and always delegate and dodge responsibility.

Unfirable 'senior leadership' who got there through tenure, or more commonly being friends with buttering up the right people.

In this organizational culture (that unfortunately very common in Europe), being tasked with an actual deliverable is a pariah role - doesn't lead to career advancement, good pay, but does lead to lots of stress and conflicts.

Creating a role that combines 'tech wizard' with 'people manager' sounds awful. It seems they hired this person as a 'fix' guy, who would magically make everything just work.

I'm sure he contributed, and tried to kinda fix the org, and the code at the same time, but being the only guy who actually fighting fires, while most of the org is either actively trying to do as little as possible, with senior leadership either doing feelgood circlejerk or playing politics, eventually you have to face the fact you're being taken advantage of, and the only reward waiting for you at the finish line is stomach ulcers.

I still remember when my previous employer has lost domain for like 3 months. Boss and his business partner have setup company and I have joined later. Business partner left.

- I was trying to figure out who have access to domain X? It is not on AWS and by whois it is under some random registrar in Europe. I got just shrug from boss. Everything works so why bother?

- After 3 years of scratching my head and try to repeatedly get it to attention we finally lost the domain (card probably expired), everyone is panicking, because emails has stopped working, so email based 2FA are not working either which has cascading impact on all services. And I am just raging in my office because I was trying to prevent this situation for 3 years to no avail.

- The European registrar did not cooperate at all. We have offered them good chunk of money, no response (weird?), eventually domain got moved around and reregistered by various bots and domain companies and I was able to get it again via domain backorder.

I have left shortly after because this was just ridiculous lack of care with good amount of reactive behavior as a cherry on the top. My take away from this is that you can't change the culture. If top is bunch of sloppy clowns, whole company is going to be the same.

>>If top is bunch of sloppy clowns, whole company is going to be the same.

This happens so often at big companies as well. Management is always assumed to be correct, and the pay grade argument always kicks in(They are paid more because you are beneath them). And this starts to show up everywhere. You can't take any initiative without sanction from the top, and they are often clueless as to what the ask is. Most of the times its rejected just to assert authority, and not on the grounds of merit.

Top bosses are also very envious and proactively trying to kill rising talent out of fear- people better than them, will replace them. To that end no good thing ever happens, if you push too hard you will be eliminated in interest of self preservation.

So by and large no good thing is ever suggested, or tried or happens. Eventually until whole business(es) die out. This happens in every company, no matter what companies claim about hiring, retaining and promoting talent. This is just how every place works.

Welcome to Hell, kid.

I was a senior manager, for much of my career, and had about a 30% hit rate, with folks listening to me. My employees had to listen to me, but I actually encouraged them to talk back, if they had issues with my direction.

My bosses and peers?

...not so much...

This was especially true of the Japanese (I worked for a Japanese company). Even though I had a pretty significant level of influence (for a Westerner), I still had to beg for folks to listen to me.

My favorite, was when my team was assigned to help a Silicon Valley startup that my company had made a deal with, after the ink was dry on the contract.

There were a lot of problems with that relationship. Most of them, were because the senior Japanese management had made some really big mistakes; chiefly because of cultural differences between the companies (the startup was actually really good, but they were a fairly typical "smoke and mirrors" Silicon Valley startup, and had a different approach to pitching that didn't work well with the Japanese. Neither side really understood the other).

We did our best, but our hands were tied. It did not end well, which was pretty disastrous.

If someone had asked me to help out, before they signed the contract, it would have been a much better outcome. I'm no captain of industry, but the problems were pretty glaring and obvious, even to us mensches in the trenches.

I've made similar ones early in my career.

The formula of Trust + Intimacy + Credibility is solid, but I'd add: solve one painful problem first, then earn the right to propose architectural changes. Ship something valuable in the first month, even if it's not perfect. That builds more credibility than any presentation.

zkmon•59m ago
> Technical influence does not start with a title. It begins with the visible impact you create.

That visible impact need not be entirely from your technical work. It is mostly from your relations, communications, the way you present yourself and the perceptions that you can manage to get from others. Infact, technology component is very little.
