Job Description
Job Description
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.
We are seeking highly motivated applicants to join our world-class team and help create the future of affordable, reliable space systems. We are looking for candidates who have demonstrated practical problem-solving and technical experience in their previous roles. Your work will be vital in transitioning a design to a real-life, mission-capable constellation of fully assembled satellites.
The Assembly, Test, and Launch Operations (ATLO) Team plans and executes all space vehicle-level integration and test activities at Millennium. ATLO creates the detailed flow of activities throughout the buildup of the space vehicle, writes and executes all test and assembly procedures used in these activities, conducts system-level through environmental testing, and performs integration to launch vehicle.
The Senior ATLO Engineer will collaborate with many teams such as Programs, Engineering, Manufacturing, Facilities, and Security to shape the direction of satellite production and help the company meet delivery targets, while maintaining a high standard of technical excellence in the assembly and test of satellites.
The Senior ATLO Engineer is invited to improve the efficiency of current processes and play a critical role in developing satellites for manufacturability and large-scale constellations. A Senior ATLO Engineer will report functionally to an ATLO Team Lead and serve under or as an ATLO program lead.
The ideal candidate is highly collaborative and a proactive problem-solver with experience in spacecraft integration, hardware-software integration, test systems, or production automation.
