Mechanical Engineer (Magnet Production & Test)

Spinor Energy Inc. • Mountain View, CA

11d • $125,000 - $250,000

About The Position

Spinor Energy's mission is to accelerate the global transition to renewable energy with breakthrough technology. We’re building the real-life flux capacitor: Superconducting Magnetic Energy Storage (SMES), a battery that stores electricity in the magnetic field of a superconducting coil. Our engineering spans four disciplines at once: superconducting materials, megawatt-scale power electronics, cryogenics, and vacuum systems. At Spinor, you'll get your hands on all of them. You will own consequential hardware architecture and first schematic 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, with proven success integrating precision DAQ systems, instrumentation (sensors, load cells), and active hardware controls (load simulators, power supplies, motors/actuators, process heaters, safety interlocks)
• Strong fundamentals in setting up early-stage assembly cells, designing specialized fixtures and tooling, and experience managing technicians to build and verify complex development hardware safely

Nice To Haves

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

Responsibilities

• Lead development of high-value manufacturing and test processes, including but not limited to thermal interface deposition, high-power electrical joint development, voltage tap/fiber optic management, and reel-to-reel verification of superconductor material properties
• Design, build, and operate Spinor’s magnet acceptance test assets for both individual pancakes and full magnetic systems, including fixturing, vacuum and cryogenic environments, electrical/thermal systems, and the data-logging backbone
• Design the processes and tools used to integrate superconductor magnets, and own the production build cell: layout, material flow, assembly/process controls and verification, part sequencing/inventory, and technician management
