As our NASA (National Aeronautics and Astronautics Administration) Mission Operations Lead Engineer, you will be the lead technical authority for Millennium’s on-orbit NASA spacecraft.  Your work will encompass the entire spacecraft mission life cycle: proposal phase, concept of operations (CONOPS) development, spacecraft and mission design, space vehicle integration and test, launch and on-orbit flight operations.  You will be responsible for all facets of the mission design, including definition of operational concepts, on-orbit procedures development, and creating advanced innovative methods for flight operations unique to each of our NASA missions.  Mission Operations requires composure in high-pressure situations, in-depth knowledge the entire space mission, and an ability to respond to calmly resolve potential anomalous scenarios in real-time.  You will be directly responsible for Millennium’s NASA on-orbit assets. 


  • Support every aspect of the mission lifecycle, from proposal/mission modeling, design, integration and test, space vehicle shipment, launch and on-orbit operations, to decommissioning
  • Define ground and mission operations requirements, and flow mission requirements back to the space vehicle
    • Define mission concept of operation and design reference missions
  • Design the ground segment, including command and control, mission planning, mission data processing, and the associated infrastructure to support all activities
  • Provide mission operations input to space vehicle fault and autonomy, including fault detection and response, autonomous space vehicle behavior, and on-board command and control
  • Develop and implement methods of operational automation, to reduce day-to-day operator responsibilities
  • Create and execute space vehicle simulator tests to validate mission/fault/autonomy design
  • Create and execute in-factory flight vehicle tests to validate mission design compatibility with flight hardware
  • Conduct critical ground segment testing, including radio-frequency compatibility testing, remote ground facility interface testing, and acceptance testing of critical ground assets/locations
  • Design and validate the mission “sequence of events” for bus commissioning, payload checkout/calibration, and mission operations
    • Plan and lead formal Mission Rehearsal events to train the mission team and to validate the mission design
  • Lead a team of spacecraft and subsystem engineers during launch and early orbit activities to commission the space vehicle(s) for service
