ATLO; Assembly, Test Launch Operations Engineer - Millennium Space Systems

Overview

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

As a Systems Engineer on the ATLO (Assembly, Test, and Launch Operations) team, you will build and test complex spacecraft for various missions, focusing on manufacturability and large‑scale constellations. You will report directly to an Engineering Team Lead and be part of the production organization.

• Conduct electrical verification of spacecraft subsystems using standard test equipment.
• Work with other teams to mechanically integrate satellite components into complex assemblies in a continuously evolving production environment.
• Generate and maintain version‑controlled test scripts for automated spacecraft testing.
• Author test procedures and plans across common satellite subsystems from engineering drawings, schematics, and ICDs.
• Validate requirements through a stringent V&V process on prototypes and flight builds.
• Interface with technicians, quality inspectors, and engineers in a cleanroom.
• Contribute to environmental testing campaigns (EMI/C, Dynamics, TVAC) as a test conductor.
• Document, analyze, and provide resolution for non‑conformances and implement corrective actions.

First Shift: 0600 – 1530. The shift lasts 9.5 hours, including a 0.5‑hour lunch break. The position is located in El Segundo, California.
