Principal ATLO (Assembly, Test, & Launch Operations) Engineer - Millennium Space Systems

Company:
Millennium Space Systems

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.

Your Team

The Assembly, Test, and Launch Operations (ATLO) Team plans and executes all space vehicle-level integration and test activities O 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 the launch vehicle.

Job Description

The Principal ATLO Engineer will lead efforts across new satellite programs and established portfolios to shape production and will be a key player in meeting and exceeding our delivery targets, all while demanding a high standard of technical excellence in the assembly and test of satellites.

The Principal ATLO Engineer is expected to shape our current and future processes, and plays a critical role in linking our business strategy to the ongoing definition and development of large-scale satellite constellations. The candidate is expected to contribute to a wide variety of program inputs including proposals, standard operating procedures, and resource management systems. They will oversee the integration of new design and manufacturing techniques into testbed and flight systems, with a strong awareness towards safety, affordability, security, testability, and mission capability.

A Principal ATLO Engineer will report to and serve under the ATLO Director.

The ideal candidate is highly collaborative and a proactive problem-solver with experience in spacecraft integration, mission architecture, and production automation. The ideal candidate can work equally well in a singular supervisory role or with multitalented teams on the production floor. A Principal ATLO Engineer has experience in these fields: design for manufacturability, process mapping, spacecraft avionics, cost analysis and earned-value management, complex mechanical integration, environmental testing, launch integration, proposal writing, or high-rate manufacturing.

The ideal candidate has an active DoD security clearance (preferred)
