Job Title: Test Engineer - R&D
Location: In-person, San Francisco
About Aurelius Systems: Aurelius Systems is a directed energy company developing edge-deployed laser systems for counter-unmanned aerial systems (cUAS)—we shoot down drones with laser guns. In an era where threats are increasingly small, numerous, and easily manufactured, our mission is to provide scalable, advanced, and cost-effective defense solutions for the US and our allies. Fresh from our initial funding round, we're building our team to launch our flagship product: the Archimedes laser sentinel. Join us in delivering cutting-edge technologies to protect our servicemen, servicewomen, and domestic security forces.
Location: [San Francisco Bay Area / Hybrid Field Work]
Type: Full-time
Team: Engineering Role Overview We are looking for a Test Engineer to own the verification, validation, and real-world performance testing of complex electromechanical and software-driven systems. This role spans lab testing, environmental testing, and frequent field deployments, working directly with hardware, software, and systems engineers to ensure what we build actually works under real operating conditions. You will be the connective tissue between design intent and operational reality. What You’ll Do Design, execute, and continuously improve test plans covering hardware, firmware, and software systems
Perform hands-on lab testing of electromechanical assemblies, sensors, power systems, optics, and embedded controllers
Lead field testing and deployments, including setup, operation, data collection, teardown, and post-test analysis
Build and maintain test fixtures, harnesses, and instrumentation setups
Develop automated and semi-automated test procedures where appropriate
Capture, analyze, and clearly communicate test results, failures, and root causes
Reproduce bugs
Validate fixes
Prevent regressions
Enforce safety procedures during high-power, high-voltage, or otherwise hazardous testing
Help define acceptance criteria and readiness gates for prototypes and production units
What We’re Looking For Bachelor’s degree in Engineering (Mechanical, Electrical, Mechatronics, Robotics, or similar) or equivalent experience
Oscilloscopes, multimeters, power supplies, DAQs
Motors, sensors, actuators, embedded systems
Experience testing systems that combine hardware + software
Strong debugging instincts and structured failure analysis skills
Willingness to travel locally and occasionally nationally for field tests
Clear written and verbal communication—especially around failures
Nice to Have Experience with robotics, autonomy, defense, aerospace, or industrial systems
Familiarity with Python, MATLAB, or scripting for test automation
Environmental, vibration, thermal, or shock testing experience
Safety-critical or mission-critical system testing background
Why This Role Matters This role determines whether the system actually works outside of CAD, simulation, and bench demos. You’ll directly influence reliability, safety, and customer trust.
