About the role
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 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’ve opened a Detroit manufacturing hub and we field test weekly on our own 400-acre private range.
The Role and Your Impact:
We need an Embedded Systems Engineer to own the layer between hardware and the application stack — board bring-up, BSP, drivers, and real-time control across Archimedes' subsystems. You'll work directly with EE, mechanical, and our robotics software team to make sure the system actually talks to itself under field conditions.
What You'll Own:
Board bring-up and BSP development on custom hardware
Linux kernel and driver work including device drivers, DMA, interrupts, and userspace interfaces
Real-time control loops for motion, power, and sensor subsystems
Hardware and software co-design alongside EEs and mechanical engineers
Debug at the metal using oscilloscope, logic analyzer, JTAG, and bus traces
Boot, flash, and update infrastructure for embedded targets including A/B partitions and OTA
What We're Looking For:
3 to 8+ years building embedded systems on real hardware
Multi-layer PCB design and IC selection
Strong C and C++ on Linux, plus comfort with Python for tooling
Hands on Linux kernel, driver, and BSP experience on at least one custom board
Real-time systems experience including PREEMPT_RT, Xenomai, or RTOS
Comfortable debugging at the hardware level with scope and logic analyzer
Where you probably come from: Defense companies, robotics, drones, automotive embedded, aerospace, or hardware startups doing real-time embedded work.
We want to talk if: You've shipped embedded code on hardware that has to work outside a lab. You've debugged a problem with a scope at 2am and won.
Not a fit if: You're a pure firmware or FPGA engineer (we have a separate role for that), you're a pure application developer with no hardware debug, or you treat the board as a black box.
Nice to Haves:
Yocto or Buildroot
ROS2 integration
Safety-critical or hard real-time experience
CAN, EtherCAT, or industrial bus experience
Education:
BS or MS in EE, CE, CS, or equivalent hands-on experience.
How You Operate:
Extreme bias for action. You ship working code on real hardware, not slideware
You debug from first principles, not intuition alone
Comfortable with ambiguity and fast iteration in a startup environment
Clear communicator across electrical, mechanical, 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 + equity
United Health Care medical, dental, and vision coverage
Flexible 18 days PTO + 5 sick days
Travel to field test events and range days
Covered daily lunches and office snacks + drinks
E-bike / scooter stipend ( Up to $500)
Direct access to leadership and real ownership over your work
