Mechanical Engineer - Equipment Engineering

In this role you design and build manufacturing equipment and processes for HTS magnet coils, enabling scalable production of a world-class fusion magnet system. You work closely with technicians and cross-functional teams to take concepts from idea to production-ready tooling and processes. You will influence design for manufacturability and continuously improve manufacturing capability in a fast-moving startup. This is a hands-on, impact-focused role in Proxima Fusion’s TechOps at the frontier of advanced manufacturing.

• Design new manufacturing equipment and fixtures for magnet manufacturing from concept to production-ready life cycle
• Conduct proof-of-concept work, benchtop testing, and tolerance analysis to validate designs
• Own subsystem designs, BOMs, specifications, and drawings; manage design changes
• Develop, document, and coordinate assembly procedures, commissioning, and operation
• Support technicians during build, assembly, and commissioning
• Troubleshoot production issues and iterate on design/process
• Provide DFM/DFA input to magnet design engineers to ensure manufacturability
• Select and manage external vendors and machine shops for components and subassemblies

• 4–6 years in mechanical design or manufacturing engineering building complex electromechanical systems or automated equipment
• Strong CAD skills (SolidWorks preferred) with GD&T and drawing creation
• Experience with multiple manufacturing processes: machining, sheet metal, welding, fabrications
• Hands-on experience building, assembling, and debugging equipment or prototypes
• Solid technical writing for work instructions and design documentation
• Comfort with ambiguity in a fast-paced startup
• Bachelor's or Master's in Mechanical Engineering or related field, or equivalent experience
• Nice to have: automation systems, PLCs, industrial sensors; FEA tools; cryogenics/vacuum/high-precision hardware; PLM/MES tools; rapid prototyping

• problem solving under uncertainty
• clear technical communication
• cross-functional collaboration
• SolidWorks CAD with GD&T
• Drawing creation for fabrication and inspection
• FEA tools (SolidWorks Simulation, Ansys)
