About The Position

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 engineers, former US military operators, and subject matter experts scaling America's directed energy dominance. We are building 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.

Requirements

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
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.
BS or MS in EE, CE, CS, or equivalent hands-on experience.

Nice To Haves

Yocto or Buildroot
ROS2 integration
Safety-critical or hard real-time experience
CAN, EtherCAT, or industrial bus experience

Responsibilities
