The problems being worked on at Swayable are by far the most interesting and impactful of my career.
The company's founders are real scientists - they understand what's possible and what's not with a team of data scientists and software engineers. It's nothing like the setup you get at companies where management really don't understand the work.
The team culture is described as a caring meritocracy and they do really deliver on that.
Cons
None … unless you're looking for a cushy big-company 9-to-5 vibe
