Own Your Future.

Modern Technology Solutions, Inc. (MTSI) is seeking Satellite Flight Software SME to fill a SETA (Scientific, Engineering, and Technical Assistance) position with the Space Development Agency (SDA). SDA is breaking the norms of the DoD acquisition cycle, delivering a new tranche of hundreds of satellites every two years. SDA is a fast-paced organization and is changing the way that the Department of Defense acquires space systems by building the Proliferated Warfighter Space Architecture (PWSA). The PWSA is composed of satellites produced by multiple satellite vendors, each of which is responsible for creating their own ground system to command and control their vehicles. The Satellite Flight Software SME will be responsible for overseeing the design, development, integration, and test of the flight software systems of the individual spacecraft vendors, including the software for the bus and payloads. The SME will work side-by-side with the spacecraft vendors, as required, to aid in their development processes and resolve flight software concerns. This position is part of an MTSI team supporting SDA in Chantilly, VA, although remote and/or hybrid arrangements may be possible, with a preference for locations in Chantilly, VA, or near one of the spacecraft vendor facilities in Denver, CO, or Los Angeles, CA.
