Senior EGSE System Engineer

The role

Own the end‑to‑end EGSE system to support spacecraft and payload AIT, ensuring it truthfully represents flight hardware, interfaces, and operational behavior. Translate system‑level and subsystem requirements into executable EGSE architectures, covering electrical, data, timing, software, and operational layers. Design, implement, and maintain robust EGSE hardware and software, including power interfaces, data buses, simulators, emulators, and automated test frameworks. Enable discovery of real flight‑relevant failure modes on the ground, including interface mismatches, timing issues, power sequencing faults, and operational edge cases. Support AIT execution and anomaly resolution, taking direct ownership of debugging, root‑cause analysis, and corrective actions across teams (payload, avionics, FSW, AIT, ground).

What we expect

• 10+ years of hands‑on experience with spacecraft EGSE, system‑level test, or AIT, with direct responsibility for EGSE design and execution.
• Direct involvement in at least one spacecraft mission that reached orbit, where the candidate personally owned or built EGSE used for flight hardware validation.
• Proven experience designing EGSE that interfaces with real flight hardware, not simulations only.
• Strong practical experience with spacecraft electrical and data interfaces (e.g. power, discretes, SpaceWire, Ethernet, CAN, UART, RS‑422 or equivalent).
• Software proficiency for test systems (e.g. Python, C/C++, or similar), including test automation, logging, and reproducibility.
• Experience with payload EGSE, high‑rate data paths, or RF communications subsystem testing.
• Familiarity with ground segment or mission control interfaces used during EGSE‑based testing.
• Experience defining or improving AIT processes, regression testing, or test infrastructure scalability. Prior work in small or fast‑moving space organizations, where ambiguity and rapid iteration are normal.
• Exposure to fault injection, stress testing, and margin testing at system level.
