Embedded Linux Developer

About the role

You'll help build and maintain SKIDATA's custom embedded Linux distribution (Yocto-based) running on our hardware CPU modules — NXP i.MX6, i.MX8M Plus and NVIDIA Tegra ARM SoCs. These modules power SKIDATA's access-control devices used in Mountains, Sports & Entertainment and Parking & Mobility division.

These are the first two hires of this team at the Kraków site. You'll work autonomously on site while collaborating closely with the wider team in Austria. No prior access-control or POS domain knowledge is required — a willingness to learn the domain is what matters.

Must-have skills

• Deep Yocto Project expertise — layers, recipes, BSP customization, BitBake internals, SDK generation, devtool workflows, and layer maintenance across releases
• Strong embedded Linux knowledge — bootloaders, systemd, kernel configuration, device trees
• Kernel driver development — writing/porting Linux kernel drivers and adapting BSPs for specific SoCs
• Boot chain knowledge — U-Boot customization, secure/verified boot, flashing and provisioning workflows for NXP and NVIDIA targets
• Cross-compilation & toolchains — ARM cross-toolchains, sysroots, multi-arch builds
• Solid C knowledge (Rust an advantage)
• Linux debugging proficiency — gdb, strace, perf, etc.
• Hardware bring-up — debugging via UART, JTAG, GPIO/I2C/SPI peripherals
• Good documentation, code quality and collaboration practices — Git workflows (PR/Gerrit-based review), handling vendor BSP forks and rebasing, code reviews

Security & quality

• Security-conscious development — secure boot, OTA update mechanisms (SWUpdate / Mender / RAUC), signed images
• CVE tracking and patching of the Yocto stack

Strong nice-to-haves

• Multimedia experience — GStreamer, Libcamera, SIP, WebRTC
• CI/CD for building images and automated testing
• Robot Framework and keyword-driven test automation
• Mainline / upstream Linux development
• Real-time Linux (PREEMPT_RT), if latency-sensitive modules apply
• Networking stack experience (complements the SIP/WebRTC work)
• Containers on embedded (Docker, Podman, balena)
• Power management / thermal tuning for ARM SoCs
