Areas of responsibility may include power semiconductor selection, switching topology development, gate‑drive circuitry, magnetics, control and feedback circuits, filtering, protection circuitry, and thermal management.
The Discrete Power Electronics Engineer will contribute to electrical designs throughout the product development lifecycle, including requirements review, circuit design, simulation, prototype development, design verification, troubleshooting, qualification, and transition into production.
This position works closely with senior engineering staff, Manufacturing, Quality, Program Management, and other cross‑functional teams to develop ruggedized power solutions for demanding defense, aerospace, industrial, and high-reliability applications.
This position is based in Murphy, NC. Relocation package offered
What You’ll Do:
Design and develop custom AC-DC, DC-DC, and/or DC-AC power conversion circuits utilizing discrete power components and custom circuitry.
Support the development of power converter architectures and selection of switching topologies based on input/output requirements, efficiency, power density, thermal constraints, reliability, and environmental requirements.
Design power stages using discrete semiconductor devices including MOSFETs, IGBTs, GaN devices, diodes, rectifiers, and other power switching components.
Design and analyze gate‑drive circuits, protection circuits, current and voltage sensing circuits, feedback networks, snubbers, clamps, filters, and supporting analog circuitry.
Design, specify, and evaluate magnetic components including transformers, inductors, and common‑mode and differential‑mode filtering components.
Perform circuit calculations, simulations, component stress analysis, tolerance analysis, worst‑case analysis, and component derating.
Analyze switching characteristics, losses, efficiency, transient response, stability, and control‑loop performance.
Select discrete electronic components based on electrical performance, switching characteristics, thermal performance, reliability, availability, lifecycle, and environmental requirements.
Develop accurate and production‑ready electrical schematics.
Work closely with PCB designers to optimize layouts for high‑current and high‑voltage paths, switching loops, grounding, signal integrity, thermal performance, EMI/EMC, creepage and clearance, and manufacturability.
