Pros & Cons
Celonis
- Strong learning and development opportunities with excellent internal mobility
- Great team culture with supportive colleagues and mentorship from leadership
- Below-market compensation compared to other tech companies of similar size
- Frequent organizational changes and restructuring with poor communication from leadership
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
Celonis
Process mining market leader with decent equity and a learning culture, but at 3,800+ people expect real corporate layers — best for those who want large-enterprise scale over startup agility.
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.
