To meet U.S. export control compliance requirements, a "U.S. Person" as defined by 22 C.F.R. §120.62 is required. "U.S. Person" includes U.S. Citizen, U.S. National, lawful permanent resident, refugee, or asylee., Bachelor's Degree or Equivalent Required, This position requires the ability to obtain a U.S. Security Clearance for which the U.S. Government requires U.S. Citizenship. An interim and/or final U.S. Secret Clearance Post-Start is required. ## Description As a Mission Operations Engineer, you will be the lead technical authority for Millennium's on-orbit spacecraft. Your work will encompass the entire spacecraft mission life cycle, from the proposal phase to spacecraft and mission design, through space vehicle integration and test, and culminating with launch and on-orbit operations. You will be responsible for all facets of the mission design, including definition of operational concepts, development of on-orbit procedures, and innovation of advanced methods of spacecraft operation unique to each space mission. Mission Operations requires composure in high-pressure situations, in-depth knowledge of both the space vehicles and ground segment, and an ability to respond to anomalous scenarios in real-time. You will be directly responsible for Millennium's critical on-orbit assets., * Lead a team of spacecraft and subsystem engineers during launch and early orbit activities to commission the space vehicle(s) for service * Perform duties of lead technical authority during mission operations for both the space and ground segments * 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 team + Define mission concept of operation and design reference missions + Improve future vehicle designs by cataloguing lessons learned from on-orbit exercises * Support the ground segment design, including command and control, mission planning, mission data processing, and the associated infrastructure to support all activities * Implement and test 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 * Forms and leads anomaly response team when off-nominal vehicle conditions arise * Contribute to customer briefings/debriefings for orbital events * Design and validate the mission "sequence of events" for bus commissioning, payload checkout/calibration, and mission operations * Contribute to Mission Rehearsal events to train the mission team and to validate the mission design This position is expected to be 100% onsite. The selected candidate will be required to work onsite at one of the listed location options. This position requires the ability to obtain a US Security Clearance for which the US Government requires US Citizenship.
