Job Details

Senior Embedded Linux Engineer (m/f/d)

The future of AI computing is light, not electrons. At Q.ANT, we are building photonic processing systems that compute with lightdelivering 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
