Spacecraft Software Engineer (Associate or Mid-Level)- 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.

Millennium Space Systems (MSS) has an exciting opportunity for a Spacecraft Software Engineer (Level 2 or Level 3) to join our team in El Segundo, CA!

Job Summary:

As a Spacecraft Software Engineer (Associate or Mid-Level) at Millennium Space Systems, you'll create the software that makes our satellites function in orbit. Your code will run on our custom avionics, process signals from sensors like our star trackers, and command actuators like the propulsion system. Your software may also interface with custom payloads and perform high-level autonomy functions to ensure our spacecraft accomplish their missions. We are looking for software engineers that can lead a small team developing the for a satellite, work with other teams to determine what the software needs to do, and then write (and test!) robust embedded C/C++ to meet those requirements. And when that code is running in space, you'll continue to support mission operations with software updates and enhancements. This position's internal job code is Software Engineer - Embedded.
