Working with design and reliability stakeholders, you'll define test plans - stress profiles, sample sizes, and pass/fail criteria - then bring them to the bench: designing and modeling test fixtures in CAD, instrumenting hardware with thermocouples, accelerometers, strain gauges, and humidity sensors, configuring data acquisition, and programming and loading chambers. As a Reliability Test Engineer at Shield AI, you'll prepare, execute, and manage environmental tests on electronic flight hardware across the VBAT and XBAT aircraft, ensuring it meets performance requirements through rigorous thermal, vibration, shock, humidity, and altitude testing.
