About Thea Energy:
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.
Position Overview:
Thea Energy is seeking an experienced, highly motivated manufacturing engineer to join its rapidly growing team. The Manufacturing Engineering role will develop and implement processes, tooling, and equipment necessary to manufacture and test high temperature superconducting ("HTS") magnets. This role will also help establish the foundations of Process Engineering and Quality Engineering at Thea Energy as we build and commission a magnet manufacturing and test facility. HTS magnets are foundational components of Thea Energy's planar coil stellarator, making compact, simpler, and lower-cost fusion systems possible. As part of a rapidly growing team, you'll be part of the organizational build-up of a leading fusion energy company. The Thea Energy team is comprised of self-motivated, creative, and fun individuals with an excitement for solving complex problems.
Key Responsibility Areas:
- Generate documentation for the manufacture of HTS magnets, including processes and procedures, work instructions, and quality criteria
- Design, build, and commission magnet manufacturing tooling and equipment
- Work iteratively with magnet engineers to incorporate design for manufacture and lessons learned
- Develop and implement virtual and physical inventory management and manufacturing BOMs
- Generate specifications for and collaborate with vendors to procure hardware that meets quality specifications
- Define roles for and coordinate onboarding of manufacturing technicians
- Track and report results and progress against program goals and milestones
- Communicate and collaborate with internal and external stakeholders
Required Experience & Skillsets:
- 5+ years of manufacturing engineering experience with a related degree
- Experience with first encounters of complex electrical and mechanical hardware assemblies, as well as process development including tooling, fixtures, machines, and automation
- Experience with metal fusion processes, including soldering, brazing, and welding
- Experience scaling from first-of-a-kind to continuous production
- Experience generating and interpreting manufacturing drawings, particularly GD&T
- Experience with planning and execution software including PLM, MRP, and inventory management
- Ability to work through and solve highly multidisciplinary engineering problems
- Ability to take initiative, work independently and as part of a team
- Exceptional work ethic, with clear communication and collaboration skills
- Experience with magnetic confinement fusion, aerospace, medical devices, or other advanced manufacturing processes
- Ability to occasionally lift objects up to 50 lbs
Company Benefits:
- Compensation: $105,000 - $130,000
- Comprehensive health benefits (e.g. medical/dental/vision)
- Employee equity stock options
- 20 days PTO
Requirements:
- Ability to occasionally lift up to 50 lbs.
- Ability to perform activities such as typing, standing, or sitting for extended periods of time.
- Willingness to occasionally travel or work required nights/weekends/on-call.
- Ability to work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, high voltage, high current, pressure systems, and cryogenics.
It’s not necessary to meet all of the skillsets outlined above. Please feel free to send us a note and tell us why you would still be a great fit for this role or Thea Energy.
