Test Engineer - R&D Aurelius Systems is a directed energy company developing edge-deployed laser systems for counter-unmanned aerial systems (cUAS). Our flagship product, the Archimedes laser sentinel, uses laser technology to shoot down drones. We are located in San?Francisco, Bay?Area, in-person only. This full-time role requires a citizen or permanent resident who can work six days a week in the downtown office. 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. 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, and prevent regressions with hardware and software teams • 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 • Comfortable working directly with oscilloscopes, multimeters, power supplies, DAQs, motors, sensors, actuators, and embedded systems • Experience testing systems that combine hardware and 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.
