Full description

We’re looking for an R&D Technician who loves building real hardware, getting their hands dirty, and making experiments actually work. If your happy place is a lab or shop, turning wrenches, wiring up sensors, fixing that one flaky connector, and helping bring bleeding-edge hardware to life; you’ll fit right in. What You’ll Be Doing • Building and assembling hardware and test setups: assembling magnet test stands, power racks, cryogenic plumbing, vacuum systems, and custom fixtures using mechanical drawings and wiring diagrams. • Hands-on wiring, soldering, and instrumentation: terminating cables and connectors, building harnesses, routing and labeling wiring, soldering boards and connectors, and installing sensors (voltage taps, thermocouples, strain gauges, Hall probes, etc.). • Running experiments and collecting data: setting up and operating DAQs, power supplies, oscilloscopes, DMMs, and other lab gear; executing test procedures; logging results; and flagging anomalies for the engineering team. • Supporting cryogenic and vacuum operations: helping assemble and maintain cryostats, handling LN₂, operating vacuum pumps and gauges, leak-checking systems, and keeping an eye on “is everything actually sealed and cold?” • Standing up and organizing the R&D lab: helping bring the lab online: setting up benches, mounting equipment, organizing tools and parts, labeling everything, and keeping the lab safe, tidy, and functional. • Debugging hardware on the bench: tracking down loose connections, miswired harnesses, flaky sensors, and mechanical fit-up issues; working side-by-side with engineers to get systems from “it kinda works” to “it works every time.” • Doing whatever it takes in an early-stage startup: from uncrating equipment and assembling racks/furniture to runs to the hardware store; you will be a core part of making the lab and company actually function. What You Bring • Hands-on build and test experience: 2+ years as a technician, mechanic, lab tech, or similar role in hardware R&D, manufacturing, automotive/EV, aerospace, electronics, or a related field. (Exceptional hobbyist/maker experience also counts.) • Comfort with tools and instrumentation: confident using hand tools, basic machine/shop tools, soldering irons, crimpers, multimeters, power supplies, oscilloscopes, and basic DAQ software. • Ability to read and follow technical documentation: comfortable working from mechanical drawings, simple CAD prints, wiring diagrams, and written procedures, and giving feedback when something does not match reality. • High ownership and reliability: you take pride in clean builds, good cable management, accurate measurements, and leaving the lab better than you found it. Bonus points for any of the following • Experience with vacuum systems, cryogenics, or high-current / high-voltage equipment • Experience with REBCO/HTS, magnets, or power electronics • Basic familiarity with Python, LabVIEW, PLCs, or test automation • Machine shop experience (CNC, manual mill/lathe, drill press, basic fabrication) • Startup-ready mindset: willingness to get the often overlooked but critical work: assembling office furniture, unpacking crates, organizing inventory, and helping build a world-class lab from the ground up.
