Equipment Engineer (Senior and above)

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. Until now, ammonia production has been a highly polluting, steady-state, high inertia process. We are developing new regimes of physics and plant design that require dynamic processes, especially for ammonia production from intermittent renewable energy sources. 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, Collaborative Fund, Third Derivative, Forbes 30u30, and more.

Job Description

You will be Ammobia’s primary R&D equipment and design engineer and lead projects to scale our processes from the bench to pilot scale. You will design, build, and optimize reactors, skids, and test stands across scales. You are comfortable getting your hands dirty, building from scratch, and identifying where to bring in outside vendors/engineers. You will play a key role on our growing team of scientists and engineers and work closely with the full technical team to identify and address key technical risks as we scale up.

You enjoy fast-paced, hands-on work, and are comfortable addressing unknowns. There will be significant opportunity to grow your role with the company. Responsibilities may include:

• Lead and own the design and build of reactor systems and process skids at the lab, benchtop, and pilot scales
• Design, specify, and integrate into process skids:

• Flow and pressure controllers, process tubing/piping, and mechanical framing
• Pressurized reactor systems, heat exchangers, compressors
• Instrumentation and industrial control systems, with an emphasis on automation and data acquisition (alongside controls engineer)

Work hands on building systems, as well as supervise and mentor junior engineers and interns

Develop and maintain a robust document management system for test equipment that includes revision control (P&ID, bill of materials, and SOP’s)

Work with external vendors to specify and/or design and procure custom equipment for reactors and test stands

Troubleshoot and resolve software, fluid handling, electronic, and mechanical equipment issues on test equipment

Support team in developing and executing test protocols for reactor various chemical and materials testing apparatuses systems

Who you are:

You are a do-it-all mechanical engineer with a bias towards action and rapid design cycles. You have industrial experience in chemicals, energy systems, aerospace, or other dynamic fluid systems. You think from first principles and move quickly to implement and test ideas. You are comfortable and experienced in leading projects, identifying needs at the project, team, and company level, and discovering and eliminating technical risks.

• 5+ years hands-on experience in relevant industrial setting
• Background in mechanical engineering, chemical engineering, electrical engineering, or similar
• Demonstrated expertise designing and building reactors, test stands, process skids, or similar from scratch (especially including Swagelok-style gas delivery systems, pressure vessels, heaters, and similar)
• Proficiency in basic mechanical design and prototyping, including 2D/3D CAD (OnShape, SolidWorks, Autodesk, or similar) and implementation through rapid prototyping
• Working knowledge of industrial instrumentation and control systems (e.g. PLC, Labview, or similar
• Ability to apply engineering principles, including heat and mass transport and thermodynamics, to design equipment, analyze experimental data, and solve problems
• Self-motivated, hands-on attitude, with a willingness to contribute at all levels
• Prior experience working with industrial design practices, codes, and standards for working with high pressure systems

Nice-to-have

• Experience in start-up environments
• Experience with hydrogen, ammonia, or other flammables/corrosives
• Experience in heterogeneous catalysis, reaction engineering, and/or separations
• Expertise in thermal equipment design, especially gas-liquid heat exchangers
• Proficiency in electrical or controls design

Who we are:

We are a small and passionate team of scientists and engineers. We value teamwork, accountability, open communication, and rapid iteration. We emphasize career growth, mutual feedback, and a fun and exciting working environment. Check out ammobia.co/careers for our full values statement and ammobia.co/team to learn more about us.
