Description

Amogy is an innovative cleantech startup on a mission to unlock ammonia's potential as a clean energy source. Driven by a vision of a more sustainable future, we've developed carbon-free energy solutions that leverage ammonia as an alternative fuel to decarbonize hard-to-abate sectors, including maritime shipping and stationary power generation. Join our dynamic team as we accelerate the commercialization of our technology and revolutionize the future of energy.

Job Summary
We are looking for a hands-on Staff Mechanical Engineer with strong mechanical design experience for complex metal components and assemblies exposed to thermal, pressure, structural, and manufacturing constraints to execute research and development projects from concept to scale-up. In this role, you will work closely with cross-functional engineering teams to design, analyze, integrate, and test reactor and separation technologies for Amogy’s next‑generation power solutions.

Key Responsibilities

• Lead the development and optimization of mechanical structures and assemblies for ammonia cracking and separation systems.
• Own assigned designs from concept through release, including 3D modeling, material selection, structural/thermal analysis, design for manufacturing and assembly, equipment selection, and detailed engineering drawing generation.
• Coordinate with cross functional teams, including FEA/CFD analysis and modeling, manufacturing, process, and testing teams, to complete project objectives.
• Own/track schedules for assigned workstreams and supplier deliverables.
• Contribute to, improve, and maintain mechanical engineering design practices, frameworks, and best-practices.
• Define and maintain mechanical requirements for temperature, pressure, load cycles, leak tightness, manufacturability, inspection, and test acceptance for assigned elevated-temperature devices.
• Provide technical mentorship and training for mechanical engineers, technologists, and technicians.

Requirements

Minimum Requirements:

• BS/MS in Mechanical Engineering with 6+ years of professional experience or PhD in Mechanical Engineering with 4+ years of professional experience in energy, aerospace, automotive, or related field.
• 2+ years of prior experience in leading projects or technical teams.
• Strong understanding of structural and thermal analysis principles, engineering fundamentals, parametric modeling, manufacturing methods, and the product development process.
• Prior experience designing and testing mechanical hardware for severe or regulated service, such as elevated-temperature metal hardware, pressure-boundary equipment, heat-transfer equipment, high-temperature piping, reactors, engines, turbomachinery, process skids, tooling/GSE, or similar energy, aerospace, or industrial hardware.
• Ability to perform, interpret, or critically review structural and thermal analysis, including hand calculations and/or finite element analysis (FEA), and translate results into design, material, manufacturing, and test decisions.
• Experience in applying standards and code to designs (e.g. ASME/BPVC Sections II-D, III, V, VIII Div 1 and 2; NFPA 86; ASTM, AWS). Proficiency/experience in all codes is not required.
• Proficiency in Geometric Dimensioning and Tolerancing (GD&T per ASME Y14.5-2018)
• Previously taken one or more hardware products, subsystems, or production/test tools from concept through prototype, validation, production release, field deployment, or commercialization.
• Excellent organizational skills and proactivity in finding solutions to complex problems.
• Ability to work in a fast-paced environment with excellent written and verbal communication skills and communicate timely updates to internal stakeholders.
• No travel restrictions with ability to travel as needed

Preferred Qualifications:

• MS in Mechanical Engineering with 8+ years of professional experience or PhD in Mechanical Engineering with 6+ years of professional experience in energy, aerospace, automotive, or related field.
• Expertise in use of ABAQUS, SIMULIA, or ANSYS.
• 4+ years of prior experience in leading projects or technical teams.
• Experience optimizing metal hardware subject to creep, fatigue, thermal cycling, thermal expansion, and pressure loading.
• Working knowledge of combustion principles and catalytic process technology.
• Direct design or test experience with ammonia, hydrogen, catalytic reactors, combustion systems, turbines, or other high-temperature chemical/energy systems is a plus.
• Experience supporting new product introduction (NPI), supplier qualification, manufacturing ramp, nonconformance disposition, root-cause analysis, or field failure resolution.
