With competitive compensation and superior employee benefits, as well as a commitment to fostering individual career growth, Airbus U.S. is the place where top talent wants to work Position Summary: 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. Position Responsibilities: The Systems Engineer (SEIT/SWIL) will serve as the primary internal owner of Airbus U.S.'s satellite digital twin, supporting software-, subsystem-, and system-level verification and validation. The engineer will operate, maintain, and enhance the digital twin environment and coordinate with the subcontractor for updates, fixes, and capability improvements. They will also develop TCL-based tests to exercise and validate system behaviors within existing SWIL workflows. This role ensures the digital twin is effectively integrated into SWIL test activities and that simulation results remain aligned with system performance and verification needs. The engineer will execute moderate to complex assignments with increasing autonomy under the Systems Engineering Manager and senior technical leadership.
