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.
**What You Bring**
* **A well-rounded electromechanical engineering skillset** spanning CAD/FEA (SolidWorks, CATIA, Ansys, COMSOL), PCB design (Altium, KiCad), 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 work** involved with early stage startups: assembling the office furniture, setting up software licenses, and forming strong external industry relationships.
