Job description

What You’ll Be Doing Building and testing HTS (high-temperature superconducting) hardware: including REBCO conductors/cables, high-current power supplies, energy storage systems, cryogenic cooling systems, and integrated test fixtures. Standing up our R&D lab: benches, instrumentation, vacuum hardware, DAQs, software licenses, and everything in between.

Owning your designs end-to-end: generating CAD and drawings, running FEA, sourcing components, working with vendors, and leading mechanical/electrical assembly. Hands-on prototyping: CNC machining and fabrication, soldering, wiring, assembling cryostats, working with LN₂, using DMMs/oscilloscopes, characterizing sensors and circuits.

Developing and debugging electronics: from sensing circuits and high-current drivers to embedded control and data acquisition. Defining requirements and translating tokamak-level system attributes: into subsystem performance metrics. Solving genuinely hard problems: across physics, engineering, and manufacturing under real-world constraints.

Collaborating closely with a small, multidisciplinary team of physicists, engineers, and technicians: sharing results quickly, making design tradeoffs explicit, and helping shape our technical roadmap. What You Bring A well-rounded electromechanical engineering skillset spanning CAD/FEA (Solid. Works, CATIA, Ansys, COMSOL), PCB design (Altium, Ki.

Cad), power electronics, embedded systems, and mechanical design/fabrication. Hands-on hardware experience across mechanical builds, electronics bring-up, test setups, and system integration. Comfort with lab tools and instrumentation: CNC machines, machine shop tools, soldering equipment, oscilloscopes, DMMs, high-current supplies, vacuum pumps, and cryogenic hardware.

Familiarity with power electronics and measurement/sensing circuits. Software proficiency: data acquisition, PLCs, Python scripting, test automation, and control systems. Bonus experience: working with REBCO tape, high vacuum, high voltage, high current, cryogenic systems, or industrial test infrastructure. Willingness to do the dirty work involved with early stage startups: assembling the office furniture, setting up software licenses, and forming strong external industry relationships.

Compensation

120k-200k base + 0.1-1% equity Salary $120,000 - $200,000 per year
