CesiumAstro is a developer and pioneer 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.

We are seeking an experienced Embedded Software Engineer II with a strong background in embedded Linux development and the Yocto build system. This role is ideal for engineers with hands‑on experience in embedded systems, including device drivers, kernel customization, bootloaders, and board bring‑up, with a preference for experience on the Xilinx platform (experience with other platforms is also valued).

As a member of our software team, you will contribute to the full software development lifecycle, from product concept through production, participating in architecture design, implementation, testing, qualification, and in‑orbit support. This role involves working closely with hardware, systems, and FPGA engineers, and provides opportunities for technical leadership and cross‑disciplinary collaboration.

This position will support Skylark , an advanced active phased array antenna system designed to unlock satellite communications that has traditionally relied on mechanically steered systems. It is designed for compatibility with a wide range of current and next‑generation satellite constellations and can be scaled to meet mission‑specific performance requirements. Skylark also offers multi‑beam capability, unlocking simultaneous communications with satellites in different orbits.

JOB DUTIES AND RESPONSIBILITIES

• Develop and port embedded Linux applications, device drivers, and libraries.
• Configure, customize, and integrate the Linux kernel and embedded bootloaders (e.g., U‑Boot).
• Maintain and evolve the Yocto‑based Linux build system within a CI / CD pipeline.
• Package and deploy software images for diverse embedded hardware platforms.
• Create tailored Linux distributions for specific embedded applications.
• Collaborate across disciplines (firmware, hardware, systems) to ensure seamless system integration and performance.
• Participate in design reviews and contribute to customer‑facing technical documentation and proposals.
