I work for a consulting company called Slalom and for 3.5 years now I don't know if I've been happier working. It's a (private) big global place, but we have a "local market model" which effectually means you feel like you're working for a much smaller company (which is your home office). I still get to do plenty of development work during projects, but I also get to work in people leadership, practice leadership, give conference talks, sell if I want to (note: I don't lol), and the best part from a developer's standpoint is that when a project is over, you just... Leave. After almost 5 years of being responsible for an ever-growing list of software I had to maintain alone at a startup, it's a really liberating feeling for my ADHD self. And yes, we're hiring worldwide!
Having `zsh` as a default shell, and having two different versions of `bash` are very different things. That's a bit like saying "macOS ships with IPython as the default Python interactive interpreter" when someone says macOS ships with Python 2.7 when 3.x is available elsewhere.
