DescriptionLocation: This role is fully onsite at our office in Houston, TX.
Job SummaryWe are looking for a highly technical Principal Mechanical Engineer with deep subject matter expertise in high-temperature mechanical system design using metal-alloy components, to execute product development engineering tasks from concept, through detailed engineering and testing, into series production. 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.
This is an individual contributor role that requires hands-on experience independently setting up, executing, troubleshooting, and interpreting FEA models for complex structural and thermo-mechanical systems.
Key Responsibilities- Serve as a hands-on individual contributor responsible for independently building, running, troubleshooting, and interpreting structural and thermo-mechanical FEA models.
- Lead structural and thermo-mechanical analysis strategy for mechanical structures and assemblies used in ammonia cracking and separation systems, guiding design optimization through FEA-led decision making.
- Guide mechanical design maturity from concept through launch by defining analysis plans, evaluating design margins, supporting material selection, informing DFM/DFA tradeoffs, and verifying detailed engineering designs through structural and thermal FEA.
- Partner with mechanical design, CFD, manufacturing, process, and testing teams to translate operating conditions, loads, boundary conditions, and test data into validated structural and thermal analysis models.
- Establish and maintain best practices for structural and thermal FEA, including modeling assumptions, meshing standards, material models, load-case definition, design allowables, documentation, and peer review process.
- Define and maintain structural integrity requirements for high-temperature devices, including allowable stresses, deformation limits, fatigue life, creep performance, pressure-boundary requirements, and thermal cycling durability.
- Present analysis findings and recommendations to peers and management, translating FEA results into clear technical guidance for design and program decisions.
Preferred Qualifications- MS or PhD in Mechanical Engineering, Aerospace Engineering, Applied Mechanics, or a related field, with advanced technical depth in structural mechanics, heat transfer, high-temperature materials, pressure equipment, or coupled thermo-mechanical analysis.
- 5+ years of experience serving as a technical lead or analysis authority for complex structural or thermo-mechanical analysis programs, including developing technical approaches, mentoring engineers, and driving implementation of design solutions.
- Experience analyzing or designing hardware exposed to ammonia, hydrogen, syngas, combustion products, or other reactive/high-temperature environments, including consideration of material compatibility, thermal cycling, pressure containment, and degradation mechanisms.
- Familiarity with coupled CFD-to-FEA or multiphysics workflows used to translate flow, pressure, and thermal results into structural and thermo-mechanical analysis inputs.
- Experience developing analysis standards, templates, review processes, automation tools, or reusable workflows that improve consistency, quality, and execution speed across different programs.
