About The Position

Stellios Technologies is building advanced high power microwave and energy systems for defense, aerospace, and energy. We are hiring a High Voltage Technician to build, wire, insulate, and operate the electrical systems that power everything we make. This is a hands-on build role. You will have tools in your hands and energized hardware in front of you, on real systems that run up to a million volts.

Requirements

Real, hands-on high voltage experience
Experience from national labs and accelerator facilities such as SLAC, and their contractors
Experience from power supply and power electronics manufacturers such as TDK-Lambda
Experience from pulsed power, directed energy, and defense primes and neo-primes
Experience from electric vehicle and automotive high voltage manufacturing such as Tesla
Experience from industrial and medical X-ray, semiconductor equipment, and utility or substation work
Ability to work from wiring diagrams, schematics, cable and harness drawings, and assembly instructions without an engineer standing over you
Safety discipline including lockout tagout, grounding sticks, interlocks, and the habit of never trusting a system you have not personally grounded
Must qualify as a U.S. person under applicable export control laws, including U.S. citizens, U.S. nationals, lawful permanent residents, refugees, and asylees, due to access to U.S. export controlled information.

Responsibilities

Wiring harness fabrication, routing, dressing, labeling, and strain relief across the whole machine
High voltage cable termination, potting, splicing, and standoff and bushing installation
Epoxy encapsulation, potting, insulation systems, and the surface prep and cure discipline that makes them hold
Assembly of high voltage power supplies, modulators, and pulsed power hardware up to one million volts
Capacitor banks, energy storage assemblies, charging systems, and the safety hardware around them
Transformer, magnetics, and inductor assembly and installation
Grounding, bonding, shielding, and corona control on hardware that does not tolerate sloppy work
Setting up and operating energized systems for test — safely, repeatably, and with the interlocks and grounding discipline the job requires
Hipot, megger, partial discharge, and continuity testing, and keeping honest records of what you measured
Troubleshooting when a system arcs, tracks, flashes over, or simply will not come up to voltage
Working directly with the engineers who designed the hardware, and telling them when a design cannot be built the way it was drawn
