Senior Embedded Software Engineer

At Cesium Astro
, we develop and pioneer out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. Our dynamic, cross‑functional environment encourages learning, development, and engagement across the organization. If you want hands‑on, interactive, and autonomous work, Cesium Astro is the place for you. We are actively seeking passionate, collaborative, energetic and forward‑thinking individuals to join our team.

In this position you will work on low‑level and high‑level software across all phases of the development process, with key projects including Linux‑based single‑board computers and high‑reliability microcontroller systems. Your responsibility will encompass software design from concept through production, including product roadmaps, block diagrams, detailed design, coding, analysis, test, qualification, and in‑orbit support. Ideal candidates possess development experience at nearly every level of the software stack—microcontrollers, low‑level drivers, board‑support packages, end‑use applications, and user interfaces—as well as experience in software testing, high‑reliability qualification, engineering and project‑management practices.

You will present engineering‑design‑review materials to customers and the executive team, and participate in proposal‑writing efforts. Excellent written and verbal communication skills are required.
