Senior Embedded Software Engineer

About the job

You work 80-100% in Zug or partially remote

• You are responsible for the setup, maintenance, and further development of our Yocto‑build environment including layers, recipes, images, and SDKs
• The integration and maintenance of Board Support Packages (BSPs), Linux‑kernel, device trees, and U‑Boot are central tasks for you
• You take over system integration with a focus on systemd, network infrastructure, security hardening, logging, time synchronization, and storage solutions
• You develop drivers and firmware in C/C++ for our ARM platforms (STM32, TI am335x, etc.)
• You analyze and solve complex problems in boot, kernel, or userspace using SWD/JTAG, trace tools, crash dumps, logs, as well as hardware measurement tools like oscilloscopes and logic analyzers
• You create and optimize build scripts in CMake/Make as well as use modern package managers like Conan or Linux-based systems (e.g., rpm)
• You develop production and test functions (self-tests, factory mode) and ensure code quality through reviews, tests, and clean documentation (state machines, boot concepts)
• In close collaboration with the firmware and hardware teams, you define interfaces and support the optimization of our production setups

• You have several years of experience with embedded Linux, especially Yocto, ideally complemented by knowledge in the RTOS world such as ThreadX
• Confident handling of embedded C and C++ is part of your daily routine, as is working with STM32 microcontrollers – whether via HAL/LL or directly at the register level
• You bring a solid understanding of ARM Cortex-M startups and linker files as well as routine in reading circuit diagrams and datasheets, plus experience in analyzing signal issues (EMI) and hardware faults
• You are familiar with topics like secure boot, signatures, SBOM, and CVE handling and have ideally already used A/B update strategies and tools like RAUC or SW update
• You have solid knowledge in implementing stacks like CANopen and in connecting BLE co-processors or TCP/IP modules
• You are proficient with Git, automation using Python or Bash, and experienced in agile working methods (Scrum or SAFe)
• You approach debugging challenges such as hard faults, race conditions, or stack/heap problems in a structured and routine manner
• You hold a degree in electrical engineering, computer science, or a comparable qualification and have confident communication skills in German and English
