About the job

About Us:

Aurelius Systems is an innovative, VC-backed defense technology startup focused on developing autonomous, edge-deployed robotics systems utilizing directed energy for counter-unmanned aerial systems (UAS).

Our mission is to create laser weapon systems capable of neutralizing drones effectively.

With a compact team of around ten engineers, ex-US military personnel, and subject matter experts, we are at the forefront of advancing America's capabilities in directed energy. Our aim is to deliver the first cost-effective, reliable, and robust laser weapon system.

Inspired by the principles of Marcus Aurelius, we embrace a culture of relentless effort, with a commitment to delivering exceptional results without excuses. We operate in a flexible environment, leveraging our San Francisco lab and office, alongside our Detroit manufacturing hub, and conduct weekly field tests on our expansive 400-acre private range.

If you're an engineer who prefers to witness your work in action rather than confined to a lab, we invite you to continue reading.

The Opportunity:

As the Power Electronics Engineer, you will lead the development of the power subsystem for our directed energy weapon systems.

Your role entails being the technical lead on all aspects ranging from battery pack architecture to laser diode integration. You will not merely implement existing designs; instead, you will define the architecture, make critical decisions, and take ownership of your system during range tests.

You will collaborate closely with the electrical engineer on the team, focusing on a depth of knowledge rather than breadth. Your responsibilities will include battery management system (BMS) architecture, high-voltage conversion, fault protection, and power delivery under various field conditions. When a power system issue arises during a range test, you will be the go-to expert, identifying the problem and implementing a solution promptly.

Your Responsibilities:

  • Design, develop, and validate battery management systems for high-voltage battery packs, ensuring safe charge/discharge cycles, cell balancing, thermal management, and fault protection.

  • Engineer high-voltage DC/DC converters, rectifiers, inverters, and diode driver electronics for optimal laser power delivery.

  • Create robust wire harnesses for high-power laser and motor systems, focusing on connector selection, routing, shielding, and environmental resilience.

  • Engage in hands-on prototyping, assembly, and testing on our expansive range.

  • Conduct rigorous electrical, environmental, vibration, shock, and robustness testing to ensure system reliability.

About Aurelius Systems

At Aurelius Systems, we are dedicated to pioneering advancements in defense technology, specifically in directed energy systems. Our mission is not only to innovate but also to empower our team to achieve unprecedented outcomes in the field of defense.
