Power Electronics Engineer

About this role

Aurelius Systems, a VC-backed defense tech startup, seeks a Power Electronics Engineer to architect and own the complete power subsystem for autonomous directed energy weapons. You'll drive battery management, high-voltage conversion, and power delivery systems from design through field deployment on a 400-acre private range.

What you'll do

• Design and validate battery management systems including charge/discharge, cell balancing, thermal management, and fault protection for high-voltage packs
• Architect high-voltage DC/DC converters, rectifiers, inverters, and laser diode driver electronics
• Design ruggedized wire harnesses and conduct hands-on prototyping, assembly, and field testing
• Execute electrical, environmental, vibration, and shock testing to validate system reliability
• Perform SPICE and MATLAB/Simulink simulations to optimize designs before manufacturing
• Generate schematics, BOMs, wiring diagrams, and documentation to MIL-STD and ITAR standards

What they're looking for

• Battery management system (BMS) architecture and high-voltage integration
• Power electronics design (48V+ conversion and regulation systems)
• Altium Designer schematic capture and PCB layout
• SPICE and MATLAB/Simulink simulation
• Thermal management and EMI/EMC design
• Wire harness design and fabrication for deployed systems
• Ruggedized system design for field environments
• MIL-STD standards and ITAR compliance familiarity
