Pros
This is the first time I can say I love my job. Great team, a company doing something meaningful, and a role that's a great fit for me. Senior leadership works hard to constantly evaluate - and tweak - how we work as an organization. It's a very thoughtful company. Personal growth is encouraged, with plenty of responsibilities given to you if you ask for it. Driven, but not slaving away. Most people go home between 5:30-7pm; some do more work from home, but not expected. Great fit if lean towards being data-driven, debate-craving, and results-oriented. It's a meritocracy, without much ego.
Cons
Senior leadership are all male and either engineers or former consultants, so pretty typical tech startup demographic. Not necessarily a bad thing, but creates a specific culture. Main complaint is we don't do as much socially as a company. Occasional after-work events, but not everyone participates so feels lackluster.
