Full-Time
On-site
$130,000 – $165,000 per year

TLDR

Architect reel-to-reel systems for superconducting tape, integrating tension control, automated inspection, and complex machine controls.

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:

We are looking for a Senior Electromechanical Engineer specializing in Web Handling in Reel-to-Reel (R2R) processes to lead the development of our core manufacturing infrastructure. This is a high-impact role where you will be responsible for the architectural design of the automated systems that process our proprietary superconducting magnets. You will act as the technical authority for web-handling and tension-control systems, guiding the transition from R&D prototypes to high-reliability industrial production lines.

Key Responsibility Areas

  • Design the hardware and controls for bespoke reel to reel process machines, ensuring seamless integration between high-precision mechanical assemblies and complex control software.
  • Serve as the Subject Matter Expert (SME) for machine design enabling roll to roll tension control, web handling and steering, winding dynamics, and in-line process modules, providing technical guidance to the manufacturing and design teams.
  • Scope and design electromechanical equipment to handle fragile high temperature superconducting tape with zero-defect tolerance.
  • Manage external vendors and integrators for the fabrication of large-scale equipment, ensuring adherence to Thea Energy’s rigorous performance and safety standards.
  • Design and implement advanced in-line inspection systems (e.g., computer vision, laser interferometry) to capture high-fidelity process data during continuous manufacturing.
  • Develop long-term strategies for manufacturing throughput, identifying bottlenecks in the R2R process and implementing automated solutions to increase yield and reliability.

    • Ideal Experience & Skillsets

  • BS, MS, or PhD in Mechatronics, Mechanical Engineering, Electrical Engineering, or related fields.
  • 8+ years of experience in the electromechanical design and commissioning of complex reel-to-reel equipment, preferably in delicate material applications (e.g., semiconductor, battery electrode, or specialized aerospace).
  • Expertise with Beckhoff/TwinCAT 3, EtherCAT, and structured text programming. Experience with "Taper Tension" and specialized winding algorithms is highly desired.
  • Expertise in 3D CAD (NX preferred) and the use of FEA or multibody dynamics simulation to validate machine designs.
  • Ability to solve "first-of-a-kind" engineering challenges where no off-the-shelf solution exists.

    • #LI-RD1

    Company Benefits

  • Salary Range $130,000- $165,000
  • Comprehensive health benefits (e.g. medical/dental/vision)
  • Employee equity stock options
  • 20 days PTO

    • 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.
