About the role

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.

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.
Support hardware bring-up, integration, and system-level validation activities.
Participate in design reviews (PDR, CDR, etc.) to ensure testability, reliability, and system robustness.
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.
We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)

5+ years of experience in test engineering, embedded systems, or systems-level development.
Experience designing and implementing hardware-in-the-loop (HIL/HITL) or system-level test environments.
Experience using lab instrumentation (oscilloscopes, logic analyzers, multimeters, etc.) for debugging and validation.
Ability to read schematics and debug issues at the electrical-software boundary.
Strong debugging mindset and ability to diagnose complex, cross-disciplinary issues.
Experience working in fast-paced, iterative development environments.

Experience with spacecraft, aerospace systems, robotics, or other high-reliability environments.
Familiarity with embedded Linux, RTOS, or firmware development workflows.
Experience with CI/CD pipelines and automated test infrastructure for hardware-integrated systems.
Experience with environmental testing (thermal, vibration, vacuum) and validation workflows.
Contributions to open-source testing frameworks or embedded systems projects.
Passion for astronomy, physics, and scientific exploration.
We encourage everyone to rest, recharge, and take care of themselves.
