Job Summary
As a senior spacecraft software engineer at Millennium Space Systems, you’ll take responsibility for creating the software that makes our satellites function in orbit. You will be involved in the design and architecture of the software for a spacecraft and leading a team to develop that software. 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 take ownership of the software for a spacecraft, determine requirements for what it needs to do, and then lead development of the software while also contributing to the software development. And when that code is running in space, you’ll continue to support mission operations with software updates and enhancements.
