I'm not sure which angle this question is asked from, but I can think of two:<p>1 - you're looking for great software engineering practices to model based on other companies, which is good.<p>2 - you're looking for a company to work at, and you really value software engineering practices, which is also good.<p>I feel like these are two different answers though. Many companies that have great practices do them because they are large, and have resources to implement them, think FAANG. It is financially worth it to have great software engineering practices to reduce friction and increase quality. These can be really interesting and have great papers written about their sometimes open sourced technology. The Google SRE program comes to mind.<p>If you're looking for a company with great software engineering practices to work at, I think that's a lot trickier. It honestly depends on team and culture, and I've found it varies widely, even between different leads. Even at big companies where I've worked, some teams just have bad engineering practices, either due to bad team culture or practical problems like lack of time or resources. Also be careful because a lot of software engineering practices aren't about writing code, committing code, or writing papers about tools and frameworks - they're about personal interactions and problem solving together. Even great software engineering practices can be perverted in a toxic culture.
