Position Overview:

Thea Energy is seeking a seasoned Manufacturing Engineer III to join our rapidly growing team. In this role, you will lead the development, validation, and scale-up of advanced manufacturing processes, complex tooling, and specialized equipment required to build and test high-temperature superconducting ("HTS") magnets. As a senior technical contributor, you will play a key role in establishing the frameworks for manufacturing development as we develop and prototype our stellarator systems.

Key Responsibility Areas:

  • 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.


Ideal Experience & Skillsets:

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


$115,000 - $140,000 a year
