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 actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

The Skylark product line is focused on the rapid design, build, and test of cutting-edge active phased array antennas (AESA) for terrestrial and airborne applications. Current programs span high-power, large-scale ground terminals for missile defense to commercial airline and helicopter connectivity solutions.

In this position, you will be responsible for low-level and high-level software in CesiumAstro’s products through all phases of the development process. Key projects will include Linux-based single-board computers and high-reliability microcontroller systems. Cesium’s goal is to create an out-of-the-box hardware and software experience which enhances our customers’ ability to rapidly integrate our products into their systems.

As a CesiumAstro software team member, you will be responsible for software designs from concept through production, including product roadmaps, block diagrams, detailed design and coding, analysis, test, qualification, and in-orbit support. The ideal candidate will have development experience at nearly every level of the software stack, including microcontrollers, low-level drivers, board support packages (BSP), end-use applications, and user interfaces. Additionally, the ideal candidate will have experience in software testing and high-reliability qualification, as well as software engineering and software project management practices.

The successful candidate will present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
