Chevron Pilot Jobs in California (NOW HIRING)

Ammobia is pioneering the first fundamental breakthrough in ammonia production since 1909. Our modular Haber-Bosch 2.0 technology operates at low pressures and high single-pass conversions, delivering 2x lower capital costs; making ammonia affordable from any hydrogen source, across scale for any use case.

Backed by strategic investors including Shell Ventures, Air Liquide, Chevron, MOL, and by the US Department of Energy, we are building the essential infrastructure for fuel, fertilizer and the future of energy.

Ammobia is hiring an R&D Engineer to advance our materials and reaction platforms across lab, bench, and pilot scales. You will design, source, and synthesize new catalysts and sorbents; design and test reactor systems; and scale your innovations through to TRL 6 pilot systems.

You will be at the heart of Ammobia’s R&D program, developing our next generation of reaction processes and proving them at commercially relevant scales and timeframes. You are comfortable wearing many hats, moving fast, and getting your hands dirty building and running systems.
