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. ## WHAT YOU'LL DO - 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. ## WHAT YOU'LL BRING - 5+ years of experience in test engineering, embedded systems, or systems-level development. - Strong programming skills in C/C++, Python, or similar languages used for test automation and system integration. - Experience designing and implementing hardware-in-the-loop (HIL/HITL) or system-level test environments. - Solid understanding of embedded systems, hardware interfaces (I2C, SPI, UART, CAN, Ethernet), and real-time systems. - 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. - Strong communication and collaboration skills across engineering disciplines. ## PREFERRED QUALIFICATIONS - Experience with spacecraft, aerospace systems, robotics, or other high-reliability environments. - Familiarity with embedded Linux, RTOS, or firmware development workflows. - Experience building simulation environments or digital twins for system validation. - Knowledge of communication protocols and telemetry systems used in distributed or remote systems. - Experience with CI/CD pipelines and automated test infrastructure for hardware-integrated systems. - Background in vision systems, sensors, or control 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. ## WHAT WE OFFER Competitive Compensation – A salary package aligned with industry standards and your experience. Equity Opportunities – Take part in our success with stock options. Flexible Work Environment – Enjoy working from our office or in a hybrid work setup with the flexibility to work remotely part of the week.
