Electrical Engineer

Aurelius Systems•San Francisco, CA

2d•Hybrid

About The Position

Aurelius Systems is a VC-backed defense tech startup focused on developing autonomous, edge-deployed directed energy systems for counter-unmanned aerial systems (counter-UAS). The company builds laser weapons to neutralize drones. They are a small team comprising engineers, former US military operators, and subject matter experts dedicated to advancing America's directed energy capabilities. Their goal is to create the first cost-effective, reliable, and robust laser weapon system. The company operates with a philosophy of taking action, achieving high output with a small team, and avoiding excuses, inspired by figures like Marcus Aurelius and Henry Ford. Aurelius Systems has a lab in San Francisco, a manufacturing hub in Detroit, and conducts weekly field tests on a private 400-acre range.
