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're a small team of engineers, former US military, 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 Principal Hardware Engineer to bring senior technical judgment across Archimedes hardware. You're a highly experienced builder who has taken systems the full way, from working prototype to hardware that ships and survives in the field, more than once. You know where systems break, where teams get stuck, and how to keep both moving.

You'll own hardware architecture across the whole system, lead its integration with electrical, power, embedded and optics, and partner with the engineering leadership on architecture and roadmap.

What You'll Own

Hardware architecture across the full system and its integration with electrical, power, embedded, and optics

Technical decisions on the hardest problems, from concept through production readiness

Release and production process for hardware, with our Detroit manufacturing hub

Pattern recognition and technical review: surfacing risk early and catching what others miss

Hands-on execution when the problem needs your specific experience to solve fast

Design and manufacturing trades across cost, mass, reliability, schedule, and field performance

The technical bar for design reviews, documentation, and release standards

Mentorship by example. Engineers learn from watching you work, not from being managed by you

What We're Looking For

10+ years designing and shipping complex hardware systems

Track record taking systems the full cycle from prototype through manufacturing and deployment, more than once

Senior IC or technical leadership background at hardware companies that actually shipped

Deep mechanical expertise plus real judgment in at least one of electrical, power electronics, or embedded

Systems that had to survive real-world conditions

Comfort being the technical anchor on a small team, not the manager of a large one

Where you probably come from: Defense hardware, aerospace, F1 and high-performance automotive, maritime, robotics hardware, or directed energy programs.

We want to talk if: You've been the person a hardware team leaned on to get a system from prototype to production, and you still like doing the hardest part yourself.

Not a fit if: You're a people manager without recent hands-on work, your experience is purely consumer, or you've spent your career on one narrow subcomponent.

Nice to Haves

Directed energy, laser or high-power systems

Defense or aerospace program experience with MIL-STD or equivalent qualification

Founder or founding engineer background at a hardware company

Manufacturing depth: you've stood up production lines or worked closely with the manufacturers who do

Active security clearance or ability to obtain one

Education

BS, MS or PhD in Mechanical, Aerospace or related field. What you've built matters more than where you went to school.

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.
