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
What We’re Looking For Bachelor’s degree in Engineering (Mechanical, Electrical, Mechatronics, Robotics, or similar) or equivalent experience
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.
