As a Senior Test Engineer, HITL, you will work across our full product line, from robotic ground-based telescope systems to future on-orbit platforms. You will design, build, and operate hardware-in-the-loop (HITL) test systems that validate the performance, reliability, and integration of our hardware and software systems.

This role is deeply hands-on: you will interface directly with real hardware, develop automated test frameworks, simulate real-world and space environments, and debug complex issues across electrical, mechanical, and software boundaries. You will report to the Systems or Embedded Engineering Lead.

Architect, implement, and maintain hardware-in-the-loop (HITL) test systems for validating spacecraft and telescope subsystems.

Design test infrastructure that integrates real hardware with simulated environments (sensors, actuators, communication links, and control systems).

Develop automated test frameworks and tooling to enable scalable, repeatable validation across the product lifecycle.

Build and maintain simulation environments for system-level testing, including fault injection and edge case validation.

Collaborate closely with embedded, electrical, mechanical, and software teams to ensure comprehensive system verification.

Debug complex system-level issues across hardware and software boundaries, including real-time and edge-case failures.

Define and execute test plans, validation procedures, and performance benchmarks for integrated systems.

Support hardware bring-up, integration, and system-level validation activities.

Contribute to CI/CD pipelines by integrating automated test suites and ensuring test coverage across releases.

Participate in design reviews (PDR, CDR, etc.) to ensure testability, reliability, and system robustness.
