Are you happier than you were before?
Are you making comparable salary? If not, are there any perks (less stress perhaps?) that tech writing gave you which programming didn't?
Not sure if this is relevant now but I found a first job in a newspaper. There is a trade group, Society for Technical Communication. You might try to network with them. Each chapter usually has a regular weeknight meeting (monthly). But membership is not free and usually the meeting is not free.
I was fortunate that my first company was small and treated me as if in a startup. They gave me a software product, gave me a license for help authoring tool (RoboHELP) and expected me to figure it out. Right now I'm not sure what the industry tool is. Some jobs just require using MS Word and some places have their own in-house help publishing tool. It was handy to edit HTML/CSS for small issues with the final HTML output (bad nested list formatting usually).
I'm not sure about the happy part. As a tech writer, I liked having a variety of things to learn but found after 6 months at a new company, the job would feel a little stale. The things I liked were having autonomy. But the downside was typically I was the one person department and usually I wished I had a team for belonging.
After working over 10 years, I think I felt my salary capped out about mid 70K (I think that was including bonus and raise for that job). But the main concern for me was I felt the opportunity for learning significant new things was capped out and I did not feel ready to be in a retirement mental frame.
These were my observations about differences with release for tech writer vs developer. On the release weeks I still stayed late but where programmers might stay until 11p or past 12a, I would typically go home latest about 8 or 9p. At the smaller companies with less process, I still got a bit of stress during release time b/c I would have to find the product changes that programmers snuck into the QA build and update the docs for.
At the end, I got a little burnt out b/c during majority of my career, I was working overtime regularly and doing long commutes but felt like my work was a necessary evil rather than impactful to the company or the product. So that has been my motivation to switch over to programming. Overall I think the main thing I felt wrong with tech writing was I did not feel a lot of job security because maybe it was not as hard as programming or some product managers assumed anyone could do it. The exception was when I had one very good tech writing manager. But if you are strong at selling yourself/marketing within the company then this is probably less of an issue. Best wishes and I don't log in here often but if you have any follow up questions, let me know.
Could you please talk about the kind of documentation you wrote? Was it always for the products that your company developed - was it end user manuals or docs for programmers? I am not sure exactly what I want to write, but at this point I am leaning towards writing for programmers (as it is more technically rewarding) than end users. I am also interested in articles like the priceonomics blog - data analysis and commentary.
It is disheartening to learn that after a decade your salary was capped at mid 70K. This is not the case with programming, I can assure you. Good luck with your transition - programming definitely can be (and it usually is) stressful, but it is more rewarding compared to a lot of other careers. I'm done with stress, that is why I am looking at other options.
Could you please comment on the type of documentation that you write on a daily basis?
