ABOUT OBSERVABLE SPACE At Observable Space, we're redefining how humanity observes and connects with the universe. We're a vertically integrated, high-growth, space technology company building industry-leading precision optics platforms for Earth and in space. Our systems are trusted by NASA, JPL, SpaceX, Boeing, Raytheon, and the US DoD, among others, and power the work of leading research institutions. We combine precision opto-mechanical hardware, embedded computing, cloud orchestration, and developer-friendly APIs into world class products. From advanced ground stations, on orbit sensor suites, free space optical lasercom, to distributed compute platforms, we deliver the foundational systems enabling continuous, real-time navigation, observation, and communication in space. Observable Space is backed by top-tier institutional investors including Lux, Upfront Ventures, RTX Ventures, Detroit Venture Partners and Embedded Ventures.   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. 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. KEY RESPONSIBILITIES - 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. BASIC QUALIFICATIONS - 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 digi
