Member of Technical Staff - R&D Engineering

We’re looking for an R&D Engineer who’s just as comfortable designing high power circuits as they are cranking out CAD for mechanical assemblies. If you love building real things and want to own the entire process of designing, prototyping, testing, and helping us scale from early builds to functional systems, you’ll fit right in. This role touches every corner of engineering: electrical, mechanical, thermal, systems, manufacturing, and software. Fusion is inherently multidisciplinary, and so is this job.

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.
