About The Position

Spinor Energy is hiring a Mechanical Engineer to develop and own its magnet production and acceptance-testing capability, with the goal of building a high-rate superconductor magnet fabrication operation. The role spans developing manufacturing and test processes, designing and operating magnet test assets, and establishing the production build cell.

The engineer will develop processes such as thermal interface deposition, high-power electrical joint development, voltage tap and fiber-optic management, and reel-to-reel verification of superconductor material properties. They will design and operate acceptance-test assets for individual magnet pancakes and complete magnetic systems, including fixturing, vacuum and cryogenic environments, electrical and thermal systems, and data logging.

The role also owns the processes and tools for integrating superconductor magnets and the production build cell, including its layout, material flow, assembly and process controls, verification, part sequencing and inventory, and technician management. Spinor Energy works across superconducting materials, megawatt-scale power electronics, cryogenics, and vacuum systems, and describes work extending from hardware architecture through bring-up, validation, and field deployment.

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Manufacturing, Robotics, Physics, Aerospace Engineering, another relevant discipline, or equivalent practical experience.
• Experience designing, building, and operating automated test benches.
• Proven success integrating precision data acquisition systems, instrumentation such as sensors and load cells, and active hardware controls such as load simulators, power supplies, motors or actuators, process heaters, and safety interlocks.
• Strong fundamentals in establishing early-stage assembly cells and designing specialized fixtures and tooling.
• Experience managing technicians to build and verify complex development hardware safely.

Nice To Haves

• Experience driving end-to-end product success across a hardware lifecycle, from initial problem statement through design, build-out, and high-rate manufacturing.
• Ability to iterate quickly and de-risk high-impact requirements early in a development cycle.
• Experience developing, qualifying, or automating high-integrity joining processes such as precision soldering, micro-welding, or adhesive bonding.
• Experience deploying non-destructive testing methodologies.
• Hands-on experience fabricating, winding, or testing superconducting magnets, HTS tape structures, or high-performance electrical machines.
• Practical familiarity with precision wire-handling, insulation application, vacuum resin potting, or cryogenic testing.
• Relevant experience in stored energy systems, aerospace manufacturing, battery pack manufacturing, or other technologies.

Responsibilities

• Develop high-value manufacturing and test processes, including thermal interface deposition, high-power electrical joint development, voltage tap and fiber-optic management, and reel-to-reel verification of superconductor material properties.
• Design, build, and operate magnet acceptance-test assets for individual pancakes and full magnetic systems.
• Develop test assets incorporating fixturing, vacuum and cryogenic environments, electrical and thermal systems, and data-logging systems.
• Design the processes and tools used to integrate superconductor magnets.
• Own the production build cell, including layout, material flow, assembly and process controls, verification, part sequencing and inventory, and technician management.
• Manage technicians building and verifying complex development hardware safely.
