Pros & Cons
Doctolib
- Mission-driven colleagues who genuinely care about improving healthcare access
- Strong growth opportunities with flexible remote policy and decent benefits
- Management can be heavy-handed — uses company principles as weapons against feedback
- French-centric culture makes it harder for non-French speakers to advance
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
Bottom Line
Doctolib
Genuine social mission (digitizing healthcare access for millions) with a fast-shipping culture, but at 3,500 people reviews cite organizational change fatigue and management inconsistency.
Fireworks AI
Choose Fireworks AI if you want to work with ex-Meta AI infrastructure engineers on cutting-edge LLM inference — but expect early-stage startup intensity and limited structure.
