Embedded Linux Engineer (Yocto / BSP)

About CIMONCIMON is an industrial automation manufacturer founded in 1999. We design and build PLCs, HMIs, industrial PCs, and SCADA software deployed in plants, refineries, water utilities, and OEM equipment across the US and globally. The roleWe are hiring an Embedded Linux Engineer to own the Linux platform that runs on our industrial hardware. You will build and maintain the Yocto-based distributions, board support, and build infrastructure that everything else at CIMON sits on top of. If you like working at the boundary between hardware and software, and you want clear ownership of the platform layer instead of a slice of someone else's stack, this is that job.What you will doBuild, maintain, and evolve our Yocto/OpenEmbedded-based Linux distributions across multiple hardware targetsOwn BSP work: kernel configuration and patches, device tree, drivers, U-Boot, and boot reliabilityManage the build system: custom layers, recipe organization, machine configurations, and release packagingHarden the platform for industrial deployment: long-term support, security updates, field recovery, and OTA updatabilityBuild and maintain CI/CD pipelines for image builds, regression testing, and release managementPartner daily with our US engineering team and our R&D team in Korea.What we are looking for3+ years of embedded Linux experience on production hardwareStrong Yocto and OpenEmbedded experience: writing recipes, building custom layers, BitBake internals, image constructionWorking comfort in the Linux kernel: drivers, device tree, boot chain (U-Boot or similar)C and Python proficiencyComfort with ARM platforms, cross-compilation, and low-level debug (JTAG, serial, logic analyzer)Disciplined about reproducible builds, version control, and release engineeringBachelor's degree in Computer Engineering, Electrical Engineering, or a related technical field.Authorized to work in the US. Nice to haveReal-time Linux (PREEMPT_RT) and deterministic tuningSecure boot, signed updates, A/B partitioning, or OTA frameworks (RAUC, Mender, SWUpdate)Industrial communication stacks (OPC UA, Modbus, EtherNet/IP, EtherCAT, Profinet)Container or sandboxed runtime experience on embedded targetsUpstream contributions to Yocto, kernel, or related projectsWhy CIMONYou run the platform layer day to day. Direction is set with hardware engineering in Korea and product in the US, but the build, the BSP, the kernel work, and how it ships is yours to drive.Hardware that compounds. Industrial gear lives in the field for many years. Your work doesn't get thrown out in the next refactor.Short path to answers. US developers, US application engineers, and Korea R&D are all one conversation away. No ticket queue, no escalation chain.Stable, profitable parent company. Active global product roadmap and a 27+ year track record.
