Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation.

Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.

Job Summary:

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.

This position’s internal job code is Systems Engineer. Our team is currently hiring for a Level 1-2.

Mission concept of operation and design reference missions
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
Implement methods of operational automation, to reduce day-to-day operator responsibilities
Assist in the creation and execution of space vehicle simulator tests to validate mission/fault/autonomy design
Assist in the creation and execution of 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
Support anomaly response team when off-nominal vehicle conditions arise
