At TYTAN , we aim to set a global standard in autonomous air defense with AI-driven, cost-efficient systems that counter unmanned aerial threats at scale. We protect people. We protect critical infrastructure. We protect European sovereignty. We are seeking an experienced and hands-on Senior Embedded Linux Engineer to join the Core team within our Platform Team. You build and scale the embedded Linux platform our products run on and make it the common foundation for every new product, from bring-up to the field. Your roadmap to make an impact One platform: Build a shared base distribution with clean per-product and per-board layers, so new hardware gets secure boot, identity, updates and observability by configuration, not by fork Product onboarding: Bring new hardware onto the platform together with the product teams: BSP integration, device tree, drivers and validation Platform contract: Define boot flow, partition layout, system services and versioned platform releases that product teams build on Chain of trust: Secure boot from ROM to userspace, verified root filesystems, measured boot and encrypted storage Device identity: Hardware-backed keys, provisioning in production and enrollment into a PKI Field updates: A/B or atomic image updates, signed and delta artifacts, automatic rollback, robust over intermittent links Node integration: Provide the platform hooks the node agent builds on: boot and update state, hardware identity, health sources and logs Supply chain: Reproducible builds, SBOM, CVE triage and a patch path that reaches the whole fleet Hardware CI: Automated flashing, boot and integration tests across all supported boards for every change D egree in Computer Science, Electrical Engineering, Computer Engineering or a related field, or equivalent experience 6+ years of embedded Linux in production, including ownership of a BSP from bring-up to series production Built and maintained a shared embedded Linux platform for several products or hardware families, consumed by other teams Shipped a connected device fleet with field updates and device provisioning, and supported it after launch Deep Yocto/OpenEmbedded including multi-machine and multi-product layer architectures (or equivalent depth in Buildroot or NixOS) Embedded Linux on ARM and/or x86: device tree or ACPI, driver development and debugging across I2C, SPI, PCIe, USB, Ethernet and CAN Boot stacks: U-Boot, UEFI, Arm Trusted Firmware, OP-TEE Secure boot on ARM SoCs or UEFI Secure Boot, dm-verity, LUKS or fscrypt, TPM 2.0 tooling Update frameworks such as RAUC, SWUpdate, Mender or OSTree Expert C, good C++, Python and shell; debugging with JTAG, ftrace and perf Reads schematics and datasheets, comfortable with oscilloscope and logic analyser Thinks in platforms: designs for reuse across products, names the trade-offs, makes build versus buy decisions and designs for the day a deployed unit fails in the field Fluent in English & Willingness to undergo a German security clearance Nice to haves Real-time Linux (PREEMPT_RT, CPU isolation) or AMP setups with Zephyr or FreeRTOS on companion cores Heterogeneous SoCs from vendors such as NXP, TI, Qualcomm or Intel Rugged COTS compute platforms Container runtimes on embedded devices Mainline kernel or U-Boot contributions Product security frameworks such as IEC 62443 or the EU Cyber Resilience Act Defense or aerospace products Why TYTAN?
