About Ammobia
Ammobia is on a mission to revolutionize the ammonia industry. We are a seed-stage startup developing Haber Bosch 2.0 – a next-generation ammonia synthesis process enabling cost-effective, clean ammonia production. Clean ammonia will support ammonia’s growing role in our decarbonized world, tackling some of the most difficult to abate sectors including chemicals, fertilizers, and heavy-duty transportation. We are supported by leading climate tech organizations including Starlight Ventures, the Department of Energy, Collaborative Fund, Third Derivative, and more.

5. Excellent data analysis skills and proficiency in Python
6. Excellent written and verbal communication skills
7. Self-motivated, proactive, and able to work both independently and collaboratively
8. Passion for sustainability and excitement about working at an early-stage start-up (prior startup experience strongly preferred)

Nice-to-have

1. BS (MS preferred) in chemical engineering, materials engineering or similar
2. Hands on experience installing and modifying manufacturing equipment
3. Demonstrated expertise and deep knowledge of heterogeneous catalysis, gas separations, heat and mass transport
4. Demonstrated team leadership experience in relevant area
