Pros & Cons
Fireworks AI
- World-class team of ex-Meta AI infrastructure engineers — technically very strong peers
- Working on LLM inference optimization which is one of the hottest areas in AI infrastructure
- Early-stage startup intensity with long hours expected and high performance bar
- Small team and rapidly evolving product means less structure, process, and career laddering
Linear
- Obsessive product craft — building the best-in-class PM tool teams genuinely love
- Deep work culture with no standups and minimal meetings — actually practiced
- Very small team = limited roles available at any given time
- High hiring bar means slow growth — patience required
