Mechanical Engineer - Equipment Engineering

The role

You will design and build machines, fixtures, and tooling used to manufacture HTS magnet coils. You will develop manufacturing processes and work hands-on with technicians to build, debug, and commission equipment on the shop floor.

What you will do

• Design new manufacturing equipment and fixtures for magnet manufacturing.
• Perform proof-of-concept calculations, benchtop testing, and tolerance stack-up analysis.
• Own subsystem designs, BOMs, specifications, and drawings.
• Develop, coordinate and document assembly procedures, commissioning and operation.
• Support technicians during equipment build, assembly, and commissioning.
• Support the production team troubleshooting issues and iterating on design or process.
• Drive non-conformances to root cause and turn findings into improvements.
• Provide DFM/DFA input to magnet design engineers.
• Select and manage external vendors and machine shops.
• Recommend equipment, tooling, or facility improvements to scale manufacturing capacity.

Required qualifications

• 4–6 years of experience in mechanical design or manufacturing engineering.
• Strong CAD skills including GD&T and drawing creation.
• Experience designing parts and equipment across machining, sheet metal, welding, and fabricated assemblies.
• Hands-on experience building, assembling, and debugging equipment or prototype.
• Solid technical writing skills for work instructions, assembly procedures, and design documentation.
• Comfort with ambiguity and rapidly changing requirements in a fast-paced startup environment.
• Bachelor's or Master's degree in Mechanical Engineering or a related field, or equivalent experience.

Nice to have

• Exposure to automation systems, control cabinets, PLCs, or industrial sensors.
• Experience with FEA tools (SolidWorks Simulation, Ansys) for structural or thermal analysis.
• Familiarity with cryogenics, vacuum systems, or superconducting/high-precision electromechanical hardware.
• Experience with PLM/MES tools for BOM and change management.
• Rapid prototyping skills: 3D printing, mill, lathe, or hand tools.

Before you apply

• Recruiter Interview
• Technical Screening
• Technical Panel
• CEO call
