About the Role

You'll own the precision motion stack, full stop. This is a senior IC role on the controls side, responsible for the architecture and tuning of precision pointing and tracking control loops, state estimation, and closed-loop integration with the tracker.

Responsibilities

  • Architecture and tuning of the precision pointing and tracking control loops
  • Closed loop tracking from sensor input through actuator command at hundreds of Hz
  • State estimation across IMU, encoder, and vision based feedback (Kalman filters, complementary filters, sensor fusion)
  • System identification and modeling of the gimbal, mount, and actuator dynamics
  • Actuator tuning, gain scheduling, and compensation for nonlinearities (backlash, friction, saturation)
  • Resonance characterization, notch filtering, and structural compensation
  • Simulation infrastructure for controls development
  • Hardware-in-the-loop test infrastructure for controls validation
  • Field characterization of the system against real targets at the range
  • Author controls documentation and tuning standards

Requirements

  • 4+ years of experience in robotics
  • Strong knowledge of fundamentals: classical controls, state space, LQR, MPC
  • Proven simulation experience and a track record of managing the sim-to-real gap on actual hardware
  • Modern C++ for real time control implementation
  • Python or MATLAB/Simulink for modeling, system ID, and analysis
  • State estimation in practice (Kalman, EKF, UKF, complementary filters)
  • System identification and frequency domain tuning
  • Direct experience with motion control hardware — servo drives, brushless motors, encoders, IMUs
  • Comfortable working at the seam between mechanical, electrical, and software
  • Understanding of latency, jitter, and how they kill control loop performance
  • Experience tuning hardware that fought back
  • This role requires access to export-controlled information or items that require "U.S. Person" status.

About the Company

  • 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.
  • 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.
