Typical projects may include functional test stands, end-of-line testers, electrical harness testers, sensor and actuator test systems, calibration stations, data acquisition systems, automated fixtures, and production test software. You will work closely with Manufacturing Engineering, Electrical Engineering, Software, Quality, Technicians, and Operations to create test systems that are reliable, fast, easy to use, and capable of scaling to high-volume production. You will own projects from requirements definition through architecture, electrical design, fixture design, software development, vendor build, debug, validation, production release, and ongoing improvement. What You’ll Do Own production test equipment for aircraft, dock, delivery pod, and subassembly builds, from concept through production sustainment. Design and deploy electrical testers, functional testers, automated test equipment, calibration stations, and end-of-line test systems. Develop tester requirements, test coverage, pass/fail limits, instrumentation strategies, and validation plans in partnership with design and quality teams. Build or specify test hardware, including electrical interfaces, harnessing, DAQ systems, sensors, actuators, power supplies, safety circuits, and mechanical fixtures. Develop production test software and automation scripts for reliable, repeatable, and high-throughput testing. Integrate
