Power Systems Engineer (High Voltage)

STEM Boomerang•Paradise Hills, NM

22d•Onsite

About The Position

Stellios Technologies is building advanced high power microwave and energy systems for defense, aerospace, and energy. We are hiring an exceptional Power Systems Engineer to develop the high voltage modulators and power supplies that drive our klystrons, gyrotrons, and other high power systems. You will own real power hardware, not just requirements or vendor management. The work spans pulsed and CW systems, energy storage, switching, magnetics, protection, controls, diagnostics, and the transition from prototype hardware to reliable deployed systems.

Requirements

A PhD in electrical engineering, power electronics, pulsed power, applied physics, or a directly relevant field, OR a BS or MS in a relevant technical field plus at least 5 years of directly relevant professional experience
Must have personally designed, built, tested, or commissioned meaningful high voltage power hardware. Experience that exists only at the requirements, simulation, project management, or vendor management level is not enough.
Strong fundamentals in power electronics, switching, magnetics, insulation, protection, controls, parasitics, grounding, and high voltage measurement.
Comfortable working around high voltage, vacuum systems, RF diagnostics, precision microwave hardware, and multidisciplinary engineering teams.
Requires access to U.S. export controlled information. Candidates 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.
Must be willing to work on site in New Mexico, Southern California, or Austin.

Responsibilities

High voltage pulse modulators for high power microwave sources
High voltage DC power supplies for CW and long pulse RF systems
Pulse forming networks, Marx type architectures, pulse transformers, resonant charging, capacitor banks, and related pulsed power architectures
Solid state switching using IGBTs, SiC devices, thyristors, or other appropriate technologies
High voltage magnetics, insulation systems, creepage and clearance, parasitic control, and field management
Fast arc detection, crowbar and protection systems, fault energy limitation, interlocks, and personnel safety
Pulse fidelity, rise and fall time, droop, overshoot, jitter, regulation, and repeatability
High voltage measurement, current measurement, RF synchronized diagnostics, controls, and automated test
Grounding, EMI and EMC, facility power interfaces, and integration with RF sources, magnets, cooling, and vacuum systems
Component selection, supplier development, prototype fabrication, commissioning, failure analysis, and production readiness
