Airbus U.S. is looking for an enthusiastic and creative Satellite System Integration and Test (SEIT) Engineer to develop solutions for satellite integration and test. We're looking for candidates who can bring exceptional engineering skills and strong experience in aerospace programs to the team.

The Systems Engineer will support the development and verification of Airbus U.S. satellite systems, contributing to software-, subsystem-, and system-level verification and validation activities. The engineer will develop verification strategies, test plans, procedures, and automated test scripts, and will execute and analyze tests across a range of satellite functions.

This role requires sufficient familiarity with GNC concepts to perform functional testing, evaluate expected behavior, and collaborate effectively with GNC and flight software teams. The engineer will support verification of GNC‑related behaviors such as mode logic, control responses, and state transitions as part of broader SEIT responsibilities.

The Systems Engineer will execute moderate to complex assignments with increasing autonomy under the Systems Engineering Manager and senior Systems Engineers.

• Support verification of the Guidance, Navigation, and Control (GNC) subsystem, including mode transitions, control responses, state behavior, and command sequencing.
• Develop and execute test procedures and automated test scripts focused on evaluating MCL functional behavior.
• Assess expected vs. observed control law performance and identify deviations or unexpected system responses.
• Collaborate with GNC, flight software, and simulation teams to understand expected subsystem behavior and resolve discrepancies.
• Analyze test data, identify anomalies specific to GNC behavior, and contribute to root‑cause investigations.
• Document test results, verification evidence, and findings related to MCL/GNC functional testing.

• Develop verification plans, test procedures, and test approaches across software-, subsystem-, and system-level functions.
• Execute broad functional validation activities outside GNC, supporting the verification of multiple satellite subsystems.
• Perform data analysis, document results, and generate required verification artifacts.
• Support cross‑functional troubleshooting during integration and test events.
• Participate in planning and review sessions to align test coverage with program requirements.

• Support system architecture trade studies and requirements updates as needed.
• Assist in refining functional specifications to align with evolving mission and customer needs.
• Contribute to system-level artifacts such as CONOPS updates, interface descriptions, and subsystem behavior documentation when required to support V&V and integration activities.

• Bachelor's degree in STEM (Science, Technical, Engineering, Math) or related scientific areas.
• Preferred:
  Master's in STEM (Science, Technical, Engineering, Math) or related scientific areas.

• A minimum of 3 years of relevant engineering experience with a Bachelor's degree, or 1 year with a Master's degree.
• Experience supporting verification and validation activities for software-,…
