Qualifications

• Tenure: 15+ years of firmware engineering; expert-level C for bare-metal and RTOS targets.
• Bootloader Authorship: Have personally written and shipped a bootloader on a Cortex-M or automotive MCU (S32K, AURIX/TriCore, RH850, STM32-class): the flash drivers, linker scripts, startup code and memory map were yours, not a vendor's. Linux/U-Boot-only experience does not meet this bar.
• Verified Boot & A/B: Have integrated cryptographic verification into a boot or update path — signature verification through an HSM/secure element or a crypto library, key handling, anti-rollback — and implemented A/B or dual-bank activation with a recovery path.
• On-Target Update Agent: Have built or substantially owned a software-update agent for constrained embedded devices (vehicle strongly preferred): flash management, resumable transfer, verify-before-activate, rollback. Cloud or campaign-tooling-only experience does not meet this bar.
• Certification Evidence: ISO 26262 (or DO-178C / IEC 61508) work products as an author: MISRA C compliance, static analysis to zero deviations, requirements-based testing with structural coverage (MC/DC at the highest levels), and traceability tooling.
• Bench Fluency: JTAG/SWD, logic analyzer, oscilloscope; reads schematics; works from the reference manual at register level.

Preferred Qualifications

• Silicon: NXP S32K3 with HSE_B (key catalogs, secure boot, A/B swap); FS26-class safety SBC integration.
• Open-Source Fingerprints: Uptane / TUF / aktualizr / MCUboot / SUIT — contributor rather than user.
• Delta Technology: bsdiff-class delta tooling and compression-aware flash budgeting on MCUs.
• Toolchain: Safety-certified RTOS (PX5, SafeRTOS or similar) and hermetic build systems (Bazel).
• Diagnostics: UDS (ISO 14229) security access and reprogramming services ($27/$29, $34/$36/$37).
• Networking & Middleware: Embedded pub/sub middleware (Zenoh / zenoh-pico, DDS) and automotive Ethernet (100BASE-T1, 10BASE-T1S).
• Hardening: Fault-injection or side-channel countermeasure experience in a boot path.
• Assessor Exposure: Direct interaction with certification bodies (TÜV, exida, UL) during assessment.
• Education: MS or PhD in Computer Engineering, Electrical Engineering or a related field.
