Job Description

Who We Are

Aurelius Systems is a VC backed defense tech startup building autonomous, edge deployed directed energy systems for counter-UAS. We build laser weapons to shoot down drones. We are a small team of ~10 engineers, former US military operators, and subject matter experts scaling America's directed energy dominance. The first cost effective, reliable and robust laser weapon system. Our namesake isn't an accident. Marcus Aurelius wrote about doing the work in front of you, every day, without excuses. Henry Ford didn't wait for permission to reinvent manufacturing. That's how we operate — small team, unreasonable output, no hiding behind the unachievable. In addition to our San Francisco lab, we opened our Detroit manufacturing hub and field test weekly on our own 400-acre private range.

The Role And Your Impact

We need a tenured Hardware Engineer to bring senior technical judgment across Archimedes hardware. You are a highly experienced builder who has seen systems go the full way. From a working prototype to hardware that ships and survives in the field. You've done it more than once. You know where systems break, where teams get stuck, and how to keep both moving. Your role is to raise the level of the hardware org through experience, architectural judgment, and hands‑on execution. You lead by example, you unblock hard problems, and you set the technical bar for how hardware gets designed and shipped at Aurelius. You'll partner with the founders and the Director of Engineering on architecture and roadmap. You'll work directly alongside mechanical, electrical, power, embedded, and optics engineers on the hardest problems the team is facing.

What You'll Own
  • Architectural direction across the hardware stack from mechanical, electrical, power, to embedded integration
  • Technical decisions on the hardest problems, from concept through production readiness
  • Pattern recognition and technical review like surfacing risk early, and catching what junior engineers miss
  • Handson execution when the problem needs your specific experience to solve fast
  • Design and manufacturing trades across cost, mass, reliability, schedule, and field performance
  • Cross-team judgment when hardware, controls, optics, and software collide
  • Setting the technical bar for design reviews, documentation quality, and release standards
  • Mentorship by example. Engineers should learn from watching you work, not from being managed by you
What We're Looking For
  • Deep experience designing and shipping complex hardware systems
  • Track record taking systems the full development cycle from prototype through manufacturing and deployment
  • Senior IC or technical leadership background at hardware companies that actually shipped
  • Deep technical judgment across at least two of: mechanical, electrical, power electronics, embedded systems
  • Pattern recognition from having built real systems before, especially systems that had to survive real-world conditions
  • Comfort operating as the technical anchor on a small team, not the manager of a large one
Nice To Haves
  • Directed energy, laser, or high‑power systems experience
  • Defense or aerospace program experience with MIL-STD or equivalent qualification
  • Founder or founding engineer background at a hardware company
  • Manufacturing depth as‑in you've stood up production lines or worked closely with the manufacturers who do
  • Active security clearance or ability to obtain one
How You Operate
  • Extreme bias for action. You'd rather build a prototype tomorrow than model it for a month
  • You characterize your own systems before the field does
  • Comfortable with ambiguity and fast iteration in a startup environment
  • You debug from first principles, not intuition alone
  • Clear communicator across mechanical, electrical, optical, and software teams
  • Self directed. You identify what needs to happen next and do it without being told
Why Join Aurelius Systems
  • Build more in 1 month than most engineers build in 1 year. We field test weekly. Your work goes downrange, not into a filing cabinet.
  • Career velocity is real. At ~10 engineers, there are no layers between you and impact.
  • Work on a problem that actually matters. Small cheap drones are changing warfare. Our laser systems are the asymmetric answer — infinite magazine, near zero cost per shot, scalable to every base, border, facility, and truck.
  • Join the densest defense startup ecosystem in the country. California is where the next generation of defense companies are being built.
How We Work

Core hours are Monday through Friday, 9 to 6. When we're sprinting toward a demo or field test, the team ramps up — nights, weekends, whatever it takes to ship. When the sprint lands, we ramp down. We don't manufacture intensity for show.

Benefits
  • Competitive salary and equity
  • United Health Care medical, dental, and vision coverage
  • Flexible 18 days PTO plus 5 sick days
  • Travel to field test events and range days
  • Covered daily lunches and office snacks and drinks
  • E-bike and scooter stipend up to $500
  • Direct access to leadership and real ownership over your work
