Systems Delivery Lead; Mechanical Process Engineer

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.

Ammobia is seeking a build-anything engineer to lead our Systems Delivery function. You will be responsible for the design and development of hardware systems to test and demonstrate Ammobia’s proprietary reaction and separation processes. You and your team will deliver custom equipment to Ammobia’s R&D and Process teams and therefore work with the full technical team of chemical, process, and materials engineers.

You are a hands on, build-focused, engineer with deep industrial expertise designing and delivering complex gas processing systems. You come from aerospace, chemicals, or energy, and you build systems beginning with first-principles understanding. You enjoy working closely with scientists and engineers across the company to develop and deliver on functional requirements. You enjoy fast paced, creative, and collaborative work; you work with a bias towards action and over communication;

and you thrive with high levels of autonomy and ownership.
There is significant opportunity to grow your role alongside the company. Responsibilities may include:

Successful applicants will have most of the following qualifications.

• Own hardware design and delivery for Ammobia’s pilot reactor and process systems
• Lead a team of 1-5 engineers and technicians
• Work closely with R&D and process teams to generate hardware system requirements and success criteria
• Work with external fabricators and suppliers to design and procure custom equipment including pressure vessels, structural supports, flow and pressure controllers
• Build, integrate, shakedown, commission, and handoff process systems to R&D and process teams
• After successful pilot, translate designs to larger-scale system deployments with system fabricators and EPCs
• Maintain high uptime and safe operations across systems
• Build and maintain P&IDs, BOMs, 3D models, and similar
• Continuously upgrade, maintain, and build new bench scale systems to support R&D
• Train technicians and engineers to operate the systems you design

• 5 years industrial experience in gas processing for chemical, energy, aerospace, or similar field
• Hands on experience designing building research and pilot scale gas processing equipment, including ownership of and blank-sheet design of P&IDs, models, BOMs
• Experience leading design and build activities on small teams
• Hands on experience commissioning and troubleshooting complex hardware systems
• Experience leading system safety reviews for gas handling equipment, including HAZOP, PHA, or similar
• Demonstrated experience working with fabricators and vendors firms to design and procure custom hardware
• Working knowledge of electrical and control system design (PLC programming experience big plus)
• Working knowledge of Python and/or MATLAB, especially for time series data analysis
• Demonstrated experience designing tests/experiments on pilot scale chemical process systems
• Deep expertise in thermodynamics, fluid mechanics, and heat transfer
• Hands on experience building gas handling hardware, such as with swagelok tubing, mass flow controllers, heaters, pressure vessels, etc
• BS (MS preferred) in mechanical engineering or similar
• Prior startup experience

• Expertise in catalysis and reaction engineering, gas separations
• Expertise in unit operation modeling or similar
• Expertise in PLC programming expertise
• Demonstrated expertise in data analysis of time series processes
