• Extensive experience building complex electro-mechanical assemblies and introducing first-of-a-kind hardware processes into full-scale production.
• Proven background in advanced joining and metal fusion processes, including high-precision soldering, brazing, electron beam, or TIG welding.
• Demonstrated success scaling low-volume development projects into continuous production environments utilizing PLM, MRP, and ERP software platforms.
• Deep expertise in drafting and interpreting engineering drawings with comprehensive Geometric Dimensioning and Tolerancing (GD&T) per ASME Y14.5.
• Experience in magnetic confinement fusion, aerospace, medical devices, defense, or high-reliability advanced manufacturing sectors.
• Strong analytical capabilities, proactive leadership, and excellent communication skills.
• Ability to occasionally lift objects up to 50 lbs.

Responsibilities

• Lead the development and standardization of manufacturing documentation for HTS magnets, including complex assembly procedures, work instructions, and rigorous quality inspection criteria.
• Own the end-to-end design, procurement, build, and commissioning of custom magnet manufacturing tooling, fixtures, and automated assembly equipment.
• Serve as the primary manufacturing liaison to the Magnet Engineering team, driving design for manufacturability, process FMEAs, and iterative design improvements from prototype to production.
• Architect and manage manufacturing BOMs, routings, and inventory workflows within PLM and MRP systems to ensure seamless execution.
• Author technical specifications, evaluate supplier capabilities, and partner with key vendors to procure high-precision hardware and capital equipment.
• Define technician roles, establish training programs, and mentor junior engineers and technical staff.
• Track, report, and take ownership of manufacturing milestones, schedule adherence, and budget constraints across primary magnet initiatives.
