Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Develop and port embedded Linux applications, custom device drivers, and libraries for space and airborne platforms. Manage the full software lifecycle from concept and design through production, qualification, and in-orbit support.
Requires a BS or MS in Computer Science or Engineering with at least 6 years of industry experience in software development. Proficiency in C/C++ and hands-on experience with embedded systems and hardware troubleshooting are essential.
Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.
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.
We are seeking an experienced Senior Embedded Software Engineer II with a strong background in developing embedded applications using Linux and Yocto. The ideal candidate will have hands-on expertise in embedded systems, device drivers, kernel modifications, and boot loaders, with a preference for experience on the Xilinx platform (though experience on other microcontrollers is also acceptable).
As a Cesium 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), and user interfaces with an emphasis on applications and data management. 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.
\nJOB DUTIES AND RESPONSIBILITIESCesiumAstro considers several factors when extending an offer, including but not limited to, the role and associated responsibilities, a candidate’s work experience, education/training, and key skills. Full-time employment offers include company stock options and a generous benefits package including health, dental, vision, HSA, FSA, life, disability and retirement plans.
CesiumAstro is an Equal Opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, disability, protected Veteran Status, or any other characteristic protected by applicable federal, state, or local law.
