Ask HN: How to transition from academic programming to software engineering?

New top story on Hacker News: Ask HN: How to transition from academic programming to software engineering? I taught myself how to code and ended up doing a PhD in a computational discipline. Programming has been a big part of my life for at least the last decade, during which I've written code almost every day, but always by myself. After graduating I joined a medium-sized company (~10^2 developers) as a machine learning engineer and realized how much I don't know about software engineering. I feel very comfortable with programming in the small, but programming in the large still feels mostly opaque to me. Issues like testing / mocking, code review, management of dev / stage / prod workflows and, most importantly, the judgment / taste required to make maintainable changes to a million LOC repository, are areas where I can tell I need to improve. Former academics who moved into software engineering, which resources did you find most useful as you made the transition? Python-specific or language-agnostic books would be most helpful, but all advice would be welcome.
