Principal Hardware Engineer

WHO WE ARE

Aurelius is the autonomous directed energy company.

We are a group of engineers, operators, and company patriots building American-made, laser-based counter-UAS systems that neutralize aerial threats.

Archimedes, our autonomous laser turret, combines a high-power laser with radar and machine vision to find, track, and defeat small drones. We design in San Francisco, manufacture in Detroit, and test onsite, on our own cUAS range.

ABOUT THE TEAM

You'll own hardware architecture across Archimedes and take subsystems from working prototype to hardware that ships and survives in the field.

You've done the full cycle more than once, you know where systems break and where teams get stuck, and you still like doing the hardest part yourself. As a Principal Hardware Engineer you will set the system-level hardware architecture, close the hardest design and manufacturing trades, and stand up the release path with Manufacturing. You'll work daily with electrical, power, embedded, optics, and manufacturing, and stay close enough to the bench and the floor to catch what the model misses.

MUST-HAVES

- Track record taking complex hardware the full cycle from prototype through manufacturing and field deployment, more than once

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

- Comfort being the technical anchor on a small team, still hands-on, not the manager of a large org

- Evidence of systems that had to survive real-world shock, vibration, and environmental conditions

- U.S. citizenship (required for export control).

WHAT YOU'LL OWN

Priority deliverables in the first 6 months:

- A system-level hardware architecture and integration plan across mechanical, electrical, power, embedded, and optics

- The hardest open design trades closed, with documented decisions on cost, mass, reliability, and field performance

- A hardware release and production process with the Detroit manufacturing hub

- Design review and documentation standards the rest of the hardware team can run against

- Hands-on debug and characterization of the current system so field failures get fixed at the root, not patched

NICE TO HAVES

It would help if…

- Directed energy, laser, or high-power systems experience

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

- You've stood up a production line, or worked tightly with the manufacturers who did

- Active security clearance or ability to obtain one.

NOT A FIT IF

- You're a people manager without recent hands-on hardware work

- Your experience is simulation only, limited to one narrow subcomponent, or purely consumer products

- You need remote or hybrid work

HOW WE WORK

At Aurelius we work what we call, 5+X. Our core operating hours are 5 days a week, Monday to Friday, 9am to 6pm Pacific Time.

The X is the honest acknowledgment that hard work sometimes takes more. That can be late nights and weekends during sprints and ramp-up periods or conferences, deployments, and events when the mission calls for it.

This role is onsite 5 days a week in San Francisco.
