At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you.

We are looking to add a Senior Flight Software Engineer I to our Internal Missions team. If you enjoy working in a startup environment and are passionate about developing software for leading-edge communications satellites, we would like to hear from you.
In this position, you will be responsible for the CesiumAstro satellite flight software and software-in-the-loop testing through all stages of the development process. Your work will include developing software to monitor, test, and control spacecraft subsystems such as attitude, command and data handling, navigation, thermal, and power. The ideal candidate will be an experienced spacecraft software engineer, motivated to develop every aspect of space mission software from Linux-based satellite operating systems to low-level embedded products. You will work and learn from a cohort of senior and principal software engineers. You will use your experience to direct, mentor, and grow a team of motivated spacecraft engineers in the development of a new satellite system.
As a CesiumAstro team member, you will work on a small team to develop satellites and put them in orbit. You will be responsible for software design to include initial architecture and block diagrams, requirements definition, implementation, code review, and validation and verification.
