## Role Overview
As our Senior Embedded Linux Engineer, you own the Linux platform on our radar sensor nodes: hardware bring-up on custom PCBs, production firmware, secure OTA updates, and long-term maintenance. You work with the hardware, radar signal processing, AI, and cloud engineers, and you set the embedded software architecture as the sensor platform scales.
## Key Responsibilities
- Lead embedded Linux bring-up on custom ARM-based hardware platforms
- Develop and maintain Yocto-based Linux distributions and BSPs including bootloaders, kernel configuration, device trees, and peripheral drivers
- Design and implement secure device platforms, including secure boot, firmware signing, and robust OTA update mechanisms with rollback support
- Design debugging, logging, and remote diagnostics infrastructure
- Work with the team to design reproducible build environments and CI/CD pipelines for embedded software development
- Define embedded software architecture and provide technical leadership, driving best practices and mentoring engineers as the team grows
## Required Qualifications
- 7+ years of hands-on embedded Linux development experience (a degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field is welcome, though equivalent practical experience counts just as much)
- Strong expertise with the Yocto Project and Linux BSP development on ARM Cortex-A based systems
- Solid C skills, plus working proficiency in at least one of Python, C++, or Rust
- Knowledge of embedded Linux security: secure boot, firmware signing, and system hardening
- Experience with Git, CI/CD, and reproducible software builds
- Ability to debug hardware/software interactions using laboratory equipment
## Nice to Have
- Experience with radar systems, RF engineering, DSP, or signal processing
- Experience with heterogeneous SoCs combining Linux and RTOS environments
- Familiarity with FreeRTOS, Zephyr, or similar RTOS
- Contributions to open-source projects (Linux Kernel, Yocto, U-Boot, RAUC, SWUpdate, Mender)
- Experience mentoring engineers and growing technical teams
- German language skills are beneficial but not required
