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
Pinecone
- Exceptional colleagues — warm, welcoming, and technically among the best in the industry
- Fully remote with strong company culture, autonomy, and genuine growth opportunities
- Significant layoffs in 2024 (30% of staff) eroded trust and reduced headcount
- Below-market base salary even with equity compensation

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.
