Base pay range $105,000.00/yr - $165,000.00/yr
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. Our proprietary swing reactor system runs at 10x lower pressures and 4x higher conversions than the state of the art, enabling economical production at any plant scale or energy source. 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 and recognized by leading climate tech organizations including Starlight Ventures, the US Department of Energy, Collaborative Fund, Third Derivative, Forbes 30u30, and more.
Job Description Ammobia is seeking a motivated and creative Reaction Engineer to develop and optimize our ammonia production process. You will be a key member of our reaction engineering team, developing and scaling our catalytic reaction process at the bench and pilot scales. Your primary focus will be the reactor – process parameters, active materials, and architectures; you will interface directly with equipment, materials, and process engineers and contribute to technical development across the company. There is significant opportunity to grow your role alongside the company.
Responsibilities
Conduct bench and pilot scale catalytic reaction process development, directly performing experimental and/or model/simulation‑based development
Design and optimize processes and reactor systems at increasing scales, alongside process and equipment engineers
Design, analyze, and optimize thermocatalytic experiments and processes
Operate, modify, and maintain state‑of‑the‑art custom reactor systems
Transfer test results and reaction processes to process engineering and scale up
Characterize, specify, and select active materials for ammonia synthesis and separation
Qualifications
3+ years’ experience in a relevant industrial setting (5 preferred)
Demonstrated expertise and deep knowledge of reaction engineering, heterogeneous catalysis, thermodynamics, kinetics, heat and mass transport
Demonstrated expertise in process development, experimental design, and optimization
Demonstrated expertise in data analysis, especially for time‑series data from dynamic processes, e.g. with Python, MATLAB, or similar
Hands‑on experience operating bench‑scale reactor equipment, working knowledge of bench‑scale gas handling/sensing instrumentation (mass flow controllers, pressure regulators, temperature sensors, pressure sensors)
Excellent written and verbal communication skills
Experience and enthusiasm to mentor junior engineers
Self‑motivated, proactive, and able to work both independently and collaboratively
Passion for sustainability and excitement about working at an early‑stage start‑up
PhD or equivalent experience in chemical, mechanical, or materials engineering
Nice‑to‑have
Hands‑on experience designing and building bench‑to‑pilot scale reactor equipment, especially developing PFDs, P&IDs
Demonstrated expertise in modeling of reaction processes (including kinetics, heat and mass transport) and validation with experimental data, e.g. with Aspen, gPROMS, ChemKin, Python, MATLAB, or similar
Experience synthesizing, manufacturing, and/or procuring catalysts
Experience in adsorbent separations, PSA, TSA or similar
Experience in pilot‑scale chemical processing
Experience in start‑up environments
Experience in ammonia synthesis, cracking, or separations
Benefits
Competitive equity grants
100% of premiums paid for healthcare, dental, vision, life insurance
401(k)
Gym benefit
Regular team social events
Paid time off, including closure between Christmas and New Years
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
