Senior Discrete Power Electronics Engineer

Why Join Aegis Power Systems, Inc.?

Aegis Power Systems, Inc. is a leading designer and manufacturer of ruggedized power electronics supporting defense, aerospace, and industrial applications. Our products power mission-critical systems where reliability, security, and compliance are non-negotiable.

As part of our continued growth, we are strengthening our quality systems, engineering collaboration, and manufacturing capabilities to ensure our products consistently meet customer, regulatory, and internal standards. You’ll join a stable, hands‑on environment where engineering directly impacts real mission outcomes.

The Senior Discrete Power Electronics Engineer is responsible for the design, development, analysis, and testing of high-reliability power conversion products utilizing discrete power electronic components and custom circuit designs.

This position requires deep understanding of power electronics related to power conversion and power factor correction. The position also requires hands‑on expertise in designing power converters at the circuit and component level, including power semiconductor selection, switching topology development, gate-drive circuitry, magnetics, control and feedback circuits, filtering, protection circuitry, and thermal management.

The Senior Discrete Power Electronics Engineer will lead electrical designs from initial requirements and architecture through detailed circuit design, simulation, prototype development, design verification, qualification, troubleshooting, and transition into production. The position will work closely with Engineering, Manufacturing, Quality, Program Management, and customers to develop ruggedized power solutions for demanding defense, aerospace, and high-reliability applications.

• Lead the detailed electrical design and development of custom AC-DC, DC-DC, and DC-AC power conversion products utilizing discrete power components and custom circuitry.
• Develop power converter architectures and select appropriate 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, diodes, rectifiers, and other power switching devices.
• 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/differential-mode filtering components.
• Perform detailed circuit calculations, simulations, worst-case analysis, component stress analysis, tolerance 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 readable, accurate, and production-ready electrical schematics.
• Work closely with PCB designers to optimize board layouts for high-current and high-voltage paths, switching loops, grounding, signal integrity, thermal performance, EMI/EMC, creepage and clearance, and manufacturability.
• Develop and maintain complete Bills of Material (BOMs) within the company’s ERP/DBA system.
• Develop thermal-management solutions for discrete power devices, magnetics, and other heat-generating components.
• Perform power-loss and thermal calculations and support the selection of heat sinks, thermal interface materials, airflow requirements, and other cooling…
