- Hands-on with A/B update schemes and at least one framework such as RAUC, SWUpdate, Mender, OSTree/greenboot or Android A/B.
- Strong C and Python; shell scripting; comfort with build systems (Yocto) and image composition.
- Bootloader and partition-level knowledge - slot selection, boot counters, rollback protection.
- Signed-artefact workflows and integration with PKI/signing services.
- Fleet-scale thinking - bandwidth, staged rollout, failure rate monitoring, recovery paths.
- CI/CD pipeline experience for embedded artefact build, sign and publish.
Other Requirements
- Cloud IoT device management platforms (AWS IoT, Azure IoT Hub or equivalent).
- Container-based edge deployment (Docker, Podman, balena-style workflows).
