Mechanical Design Engineer - Pressure Boundary Hardware & Skid Integration

• Own detailed mechanical design of the machine and supporting systems, including the turbomachinery test section, pressure boundary components, skid structure, and piping.
• Produce released drawings with disciplined GD&T and drafting practice.
• Work with vendors to bring designs from drawing to assembled hardware.
• Manage interfaces and tolerance stacks across the machine so parts fit together cleanly.
• Apply DFMA so designs work for early prototypes and for future production.
• Partner with analysis teammates to verify the structural and thermal performance of your designs.
• Assemble, build, and test the hardware you design.

• BS or higher in mechanical engineering, aerospace engineering, or a related field.
• Proven experience taking complex mechanical hardware from concept through released drawings, test, and validation.
• Strong CAD skills (SolidWorks, NX, Onshape, CREO, or comparable) and GD&T per ASME Y14.5.
• Practical knowledge of machining, fabrication, and assembly, and how design decisions affect manufacturability.
• Sound judgment on how designs interact with structural, thermal, and sealing requirements.
• Strong communicator who is eager to learn and to teach.

Preferred Experience

• FEA, bolted joint analysis, and thermal growth assessment of mechanical hardware.
• Elastic-plastic stress analysis, and creep or creep-fatigue assessment of high-temperature alloys.
• Mechanical design for high-pressure, high-temperature systems.
• Packaging machinery, piping, and balance-of-plant equipment onto skids or frames in a compact, buildable, serviceable layout.
• Design of rotating machinery or turbomachinery hardware.
• Startup or early-stage company experience.

• Own hardware at the center of the company’s first megawatt-class system.
• Go from CAD to assembled, tested hardware on short cycles, with your hands on the build.
• Broad scope across nearly every component of the machine, with room to grow as the team scales.
• Meaningful equity ownership.
• Medical, dental, and vision coverage.
• 401(k) plan, paid holidays, and PTO.
• Fully stocked kitchen with snacks, coffee, and lunch.
