I had to have this talk with my partner recently, who works at a small-ish company that hires people competent with data science, but absolutely useless when it comes to architecture, git or even setting up a python development environment. She does all of those things really well and ended up putting a lot of effort into fighting chaos (spaghetti code, spaghetti git flow, a lot of copy pasted code that doesn't have to be, a complete lack of dependency management, no automation for anything) at that place. I stepped in when I suggested some shared vacation days and she refused because she wouldn't be there to be her team's guard rails. That screams leadership failure to me. Keeping in mind she barely gets paid better than a junior dev.
