Job summary

Poseidon Aerospace in the San Francisco Bay Area seeks a Test and Validation Engineer to design and run hardware-in-the-loop benches, simulation environments, and automated validators that enable every flight software release and avionics hardware to pass before flight.

The role focuses on environmental and durability testing, fault injection, data pipelines, and supporting ground and flight tests, with travel to the flight test site as needed.

Qualifications

• B.S. in electrical, mechanical, aerospace, or computer engineering, or equivalent experience.
• 2+ years testing complex electromechanical or embedded systems.
• Proficiency in Python and working knowledge of C or C++.
• Experience building or operating hardware-in-the-loop, software-in-the-loop, or automated test systems.
• Hands‑on electrical debugging skills and familiarity with common vehicle data buses.

Responsibilities

• Bring up and maintain hardware-in-the-loop benches with flight computers, actuators, sensors, and power hardware.
• Maintain software-in-the-loop environment and the real-time simulation that drives the benches.
• Integrate vehicle, sensor, and actuator models from GNC and flight sciences into the simulation.
• Write validators: automated checks that evaluate simulation, bench, and flight data against requirements.
• Build automated regression testing that runs each flight software release through simulation and hardware-in-the-loop.
• Develop fault injection for sensor, actuator, data bus, and power failures.
• Build data pipelines and analysis tooling for test and flight data.
• Design and run environmental and durability tests on aircraft hardware, including vibration, thermal, and ingress.
• Integrate instrumentation and data acquisition on test rigs.
• Write test plans and procedures from requirements and failure mode analyses, and report results.
• Investigate anomalies found in test and drive root cause with the owning team.
• Support aircraft ground test and flight test with validators and data analysis, including travel to our flight test site.
