About The Position

Aurelius Systems is a directed energy company developing edge-deployed laser systems for counter-unmanned aerial systems (cUAS). We are seeking an inventive Power Electronics Engineer to drive the design, development, and validation of robust battery and high-voltage power systems for rugged, edge-deployed laser defense systems. You will lead battery management systems, diode driving electronics, high-voltage wire harnesses, and field-ready prototype validation. This role spans conceptualization through production, emphasizing a strong bias toward hands-on testing and iterative electronics prototyping in demanding defense environments.

Requirements

3-8 years in power electronics or electrical engineering roles (defense, aerospace, robotics).
Proficient in electrical design tools (SPICE, MATLAB/Simulink, Altium Designer).
Strong background in battery management, high-voltage electronics, and diode driving circuits.
Hands-on experience with wire harness design and rugged electronic system assembly and integration.
Familiarity with thermal management, EMI/EMC considerations, and defense-grade specifications.
BS/MS in Electrical Engineering, Power Electronics, or a related field.
Extreme bias for action, rigorous testing mindset, and strong problem-solving abilities.
Excellent communication, collaboration, and adaptability in a fast-paced development environment.

Nice To Haves

Experience with long-duration system deployment in harsh environments.
Familiarity with MIL-STD standards and ITAR compliance.
Background in EMI/EMC design and shielding.
Security clearance or ability to obtain one.

Responsibilities

Develop and validate battery packs and management electronics, ensuring effective thermal and power management
Conduct thermal and electrical performance analyses and testing for rugged battery systems.
Architect battery systems for rapid power delivery.
Design high-voltage DC/DC converters, rectifiers, inverters, diode drivers, power distribution units, and related control circuits
Perform electrical simulations (SPICE, MATLAB/Simulink) to optimize performance, efficiency, and reliability.
Create ruggedized wiring harnesses suitable for high-power laser diodes and motors
Select and specify connectors, cables, and components adhering to electrical, environmental, and mechanical standards.
Drive hands-on prototyping, assembly, and rigorous field testing of power electronic systems
Execute electrical, environmental, vibration, shock, and robustness tests to validate system reliability.
Conduct DFM reviews to optimize electronics designs for efficient, reliable, and cost-effective production
Collaborate closely with suppliers and fabricators to ensure manufacturability and quality standards.
Partner with mechanical, optical, and robotics teams to integrate electronics into laser platforms
Provide technical guidance during system assembly, integration, and field deployment.
Generate detailed schematics, BOMs, wiring diagrams, and assembly instructions.
Ensure compliance with relevant safety standards, MIL-STD, and ITAR requirements.
