Manufacturing Engineer III

About the role

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

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

Qualifications

Bachelor’s degree in Mechanical, Manufacturing, Aerospace, or Electrical Engineering (or related field) with 7+ years of hands-on manufacturing engineering experience

Skills

• 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
