Embedded Systems Software Engineer (OS and Bare-Metal)

At Ubitium, we believe the best engineering happens when people with different perspectives tackle hard problems together. We welcome applicants from all backgrounds and experiences. What matters most is curiosity, skill, and the drive to build technology that improves the world. If that resonates with you, we’d love to hear from you. Our team members come from some of the best universities in the world and left some of the largest tech companies to build something truly remarkable. We are looking for an Embedded Systems Software Engineer to join our team developing software for our RISC-V SoC. You and your team will be responsible for the development of a bare-metal Hardware Abstraction Layer (HAL) for our RISC-V SoC. The HAL is used for testing and proof-of-concept applications. Porting and maintaining firmware (OpenSBI), (real-time) operating systems (Linux, Zephyr), and the bootloader will also be a part of your responsibilities. The development of a BSP (OpenEmbedded/Yocto) and porting applications for testing and benchmarking (SPEC CPU) is expected as well. Prospective team members require solid C skills and an interest in embedded / bare-metal and (RT)OS development; an understanding of CPU and memory systems (RISC-V a plus); exposure to bootloaders or RTOS (e.g. Zephyr, FreeRTOS) is welcome. Hardware debugging experience is a plus. Bachelor’s degree (or equivalent experience) and first relevant experience (internships, projects) is desired. Relocation required. Currently 4 days on-site, 1 day remote. Policy may change. Competitive salary plus stock options 30+ days of paid vacation Relocation support Full German social security and universal healthcare A modern office Free snacks, coffee, and drinks Work with people who actually know their stuff – computer architects, hardware nerds, and engineers who love tough problems. A culture where new ideas matter, but so does respect and collaboration. Space to grow: pick up new skills, dig into areas that interest you, and shape your own path. Get hands-on with real implementations of AI and signal processing – not just slides or buzzwords. An inclusive team where different perspectives are valued and everyone contributes. We are constantly looking for talent. We recruit through multiple channels – friends & colleagues, universities and professors we know, recruiters, conventions, e-mails and LinkedIn. Join us today.
