Job description

About Ammobia

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.

About the role

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.

What you will do

  • Conduct and manage tests on advanced reactor systems and materials characterization systems, including specifying/building custom reactor equipment

  • Transfer lab and bench scale R&D learnings and achievements to pilot demonstration, including developing operating procedures, designing test campaigns, leading lab- and pilot-scale system turnarounds, and analyzing data

  • Design and optimize active catalysts, gas sorbents, and formed composite materials, including via both internal development and external research programs

  • Develop analytical and computational models of gas-solid reaction processes, set target specifications, link ex-situ measurements to in-reactor performance, transfer reaction engineering knowledge to plant process engineering team

  • Work with a small team of scientists, engineers, and technicians

  • Develop intellectual property across materials, process, and reactor development

  • Perform all work in a safe manner and help promote lab safety culture

Requirements

  • Deep quantitative understanding of thermodynamics, kinetics, and heat/mass transport

  • Deep expertise in heterogeneous catalysis, gas sorption, and/or reaction engineering

  • Demonstrated expertise transferring R&D designs and learnings to pilot scales

  • Demonstrated expertise developing and owning test plans and data outputs reactor and chemical process systems

  • Hands on experience specifying, designing, and building custom research and pilot scale chemical equipment, including working knowledge of automation and control systems

  • Experience working with technicians and operators to execute test plans
