• Architect and bring up hardware-in-the-loop benches
• Own the simulation infrastructure including software-in-the-loop and real-time simulation
• Define the validator framework and release criteria
• Design fault injection and rapid fault-finding campaigns
• Work with flight software to define test-mode features
• Turn mission profiles into qualification and life-test plans
• Develop ways to reproduce flight loads and correlate test conditions to flight data
• Develop health monitoring and anomaly detection from vehicle telemetry
• Lead environmental and durability test campaigns
