Not OP, but I worked for a similar founder. The only work he wanted software engineers to do was writing code, and not just that... only 1. code that added a customer visible feature or 2. code that fixed a major, customer-facing bug that a customer actually complained about. Fixes for bugs not discovered by customers? No. Performance improvements? No, not even visible ones. Refactorings? No. Technical debt cleanup? No. Build speedups? No. Update the code to work on a recent compiler? No. It gets better! Version control? No. Bug tracker? No. Unit tests? No. I had to implement the above three on my free time. Standing up dedicated build and test infrastructure? LOL get real. Eventually, I was able to argue for a few of these, but it was always a fight.

The reason I stayed was that the hiring market is not always that great, and it tends to be much harder to find a new job than HN would have you believe. This idea that most of us can simply "walk into any" company and get a job is fiction in all but the hottest job markets.
