Senior Embedded Linux Engineer (m/f/d)

Your mission The future of AI computing is light, not electrons. At  Q.ANT , we are building photonic processing systems that compute with light—delivering a scalable, energy-efficient alternative to transistor-based architectures for next-generation AI and high-performance computing. As  Senior Embedded Linux Engineer (m/f/d) , you take technical ownership of our embedded Linux stack: from custom Linux images and kernel/device drivers to production-ready field deployments. You'll work with technologies such as Yocto, PetaLinux, and Zephyr RTOS, actively shaping the interface between photonic hardware and software. Your Impact & Responsibilities Define and own the in-house embedded Linux stack and embedded software for our photonic AI accelerators Develop and maintain custom Linux images (Yocto/PetaLinux) as well as kernel and device drivers Interface on-chip and off-chip components via MMIO, AXI, PCIe, SPI, I2C, and UART under real-time requirements Define and develop host-Linux-based components, including Reliability, Availability, and Serviceability (RAS) tasks in the Linux host system Establish best practices, tools, and methods for building custom Linux and embedded software solutions Coach and develop junior and mid-level engineers Collaborate closely with R&D software engineers, processor architects, and digital design engineers Ensure successful bring-ups and field deployments Your profile M.Sc./M.Eng. in Computer Science, Computer Engineering, or a related field; equivalent industry experience also considered 3+ years of hands-on experience building custom Linux images and device drivers 3+ years of experience in low-level software development and RTOS Deep understanding of the Linux build system Hands-on experience interfacing on-chip and off-chip components via MMIO, AXI, PCIe, SPI, I2C, UART Understanding of services design in a Linux environment Solid command of C/C++ and Python; experience with Yocto and/or PetaLinux Experience with CI/CD pipelines and agile development methodology. Why us? Work on the leading edge: Photonic AI acceleration technologies that will define the next decade of computing - already validated in production HPC environments Make impact at scale: Help solve one of computing's biggest challenges—making growing demand in compute and sustainability go hand in hand Own your work from day one: Broad autonomy and decision authority with direct impact on product success and the future of AI infrastructure Fast-track your growth: Work on challenges with few industry precedents—every problem you solve becomes new institutional knowledge and potentially industry-defining IP World-class team: Collaborate alongside a passionate, international, cross-functional team of experts in photonics, processor design, and AI systems Direct access to leadership: Work closely with the company’s founders, including CEO Dr. Michael Förtsch, and the Q.ANT senior leadership team  Collaborative culture: Innovative…
