Reliability Test Engineer

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. This is a highly hands-on role. 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. You’ll frequently run several campaigns at once, owning the equipment scheduling needed to keep them moving without compromising data quality.

Once tests are running, you’ll operate the equipment, monitor for and investigate failures, and reduce and document results in clear reports - including the plots and visualizations stakeholders rely on to make disposition and qualification decisions. You’ll work with cutting-edge deep-tech hardware, collaborate across disciplines, and directly influence product quality and long-term reliability over the vehicles’ lifecycles.

What You’ll Do

• Operate and continuously improve a world-class environmental test lab for electronics that includes HALT/HASS chambers, thermal-humidity chambers, vibration/shock equipment, and data acquisition equipment.
• Develop and implement lab procedures for use of environmental test equipment, test setup and tear down, data acquision, and test reporting.
• Perform reliability tests on electronic products, including thermal cycling, temperature-humidity soaks, HALT, HASS, vibration, and shock testing.
