Bottom Line
Poolside
Choose Poolside if you want cutting-edge code AI research on a remote-first flat team (ex-GitHub CTO leadership) — but expect early-stage ambiguity and comp that trails the larger AI labs.
Sierra
Choose Sierra if you want elite founders (Bret Taylor, Clay Bavor) and strong equity at a $10B enterprise AI company — but it's in-person-first and the competitive intensity won't suit everyone.
