Millennium Space SystemsMillennium 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.
