Ask HN: What non-technical skills make a senior dev and how to develop them?

My comment was a sort of provocation, but I see that some people seem to agree with it. It makes me a bit sad, but unfortunately sometimes it's pretty hard to change things - if at all!

The other comments are all relevant and very good, but they seem to overlook one important aspect: the company's attitude. What all those comments have in common is that they assume things work according to Tom DeMarco's book Peopleware. I have learnt on my own experience that they don't. I have had the chance to work with 1)poisonous, 2)negative, 3)defensive (see the psychological meaning), and 4)offensive (... no psychology needed here) senior developers. Some nicer/more experienced than others, no doubts, sometimes also due to the lack of communication skills (English is not everyone's first language, and I do understand it). However, these ones were senior due to the number of years spent in the company OR their age. That's why I think that the companies that value someone's skills (I like to see them like technical skills, IQ and EQ) for their promotions are the minority.

All the 'soft skills' that other commenters have mentioned are definitely useful things to have but they're things to learn when you want to stop coding soon and move in to a more management oriented role. If you still want to write code as a senior, learn to write better code.

In my opinion a senior developer is someone who writes software that can be maintained without their presence. That means less clever, impressive code and more boring code that's simple and straightforward to understand that just does what it's supposed to do. It means reproducible deployments. It means tests which are up-to-date and working. It means everything is documented in a way that a junior developer, or even someone non-technical, can get value from.

In short, it means being organised.

Confidence. The ability to push back and stand up for the other developers on the team and your craft.

One of the best resources for improving your soft skills is the book "How to win friends and influence people". It's about 80 years old now, but still the best work in its category. I keep a copy at my desk for quick reminders.

Whatever it takes to make money for customers. That's it.

No, I'm not being snarky, so hear me out...

I've met and worked with many developers over the years and lots of them have become very good with technology and user domains, but still have struggled to "crack the digital ceiling". These are brilliant people who have achieved serious things, but are still not recognized by the big decision makers as "senior", whatever that means.

Then there are a select few who always get the big gigs, big money, and big reputations. Why? Because they make money for their customers. There are lots of non-technical skills that help them, but I think the biggest is their ability to separate the signal from the noise and zero in of the most important things to work on and to get them done. It's almost like they have "profitability radar". And this rarely requires any special technical or people skills. All they really have to learn is a good grasp of the technology, a deep understanding of the customer's domain and business, and the ability to get things done through others. And how did they develop them? By good old fashioned grunt work, whether digging into the bowels of the system or getting up off their butts and relentlessly going around finding out whatever they needed to know.

Once you've figured out the best thing(s) to work on to make money, got them onto the decision makers' radar, and found a way to get them done one way or the other, you are no longer a dev or even a senior dev. You're now a digital rainmaker, the most senior dev of all.
