Pros & Cons
Brex
- Innovation-driven culture with incredibly smart, passionate, and supportive colleagues
- Remote-first with strong benefits — time off actively encouraged with flexible scheduling
- Culture of overworking — many departments understaffed relative to workload expectations
- Multiple rounds of layoffs in recent years have created uncertainty and morale challenges
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
