We've got a ton of job openings; mostly in the Node.js space, but also for .Net engineers, Devops, front-end engineers, DBAs, non-node JS devs. Pretty much everyone.
I joined 4 or 5 months back and am very happy here. SF Office has a great nerdy culture; lots of tech talks, hosted meetups, engineer-friendly policies (sane WFH, good vacation, 20% policy, 'boyscouting' (fixing code unrelated to what you're working on) is encouraged). I very much enjoy working here, and I think most engineers would too.
