Hyderabad, Telangana
Job Summary
Own the software update and device lifecycle stack for connected edge products — robust A/B and image-based update mechanisms, rollback safety, fleet-scale rollout, and long-lifecycle maintenance across multiple product variants.
Key Responsibilities
Design and implement robust OTA update mechanisms — A/B (dual-slot) updates, image-based updates (OSTree class), delta updates and container/application-level updates.
Guarantee power-fail-safe, atomic updates with verified rollback and health-check driven commit logic.
Integrate update flows with secure boot and signing infrastructure so only authenticated artefacts are installed.
Build and maintain update agents, update servers/backends integration, and campaign/rollout tooling including staged and canary rollouts.
Manage partition layouts, bootloader slot switching, filesystem strategy and storage wear considerations.
Define device lifecycle management flows — enrolment, identity, configuration management, telemetry, remote diagnostics and decommissioning.
Support long-lifecycle maintenance: LTS branching, CVE monitoring and security patch delivery across fielded variants.
Build failure-injection and update regression testing including interrupted-update and downgrade scenarios.
Skill Requirements
8–10 years in embedded systems with strong ownership of update/lifecycle infrastructure.
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).
Filesystem expertise — ext4, F2FS, UBIFS, SquashFS, dm-verity.
Regulatory-driven update obligations (EU CRA, IEC 62443 patch management).
Telemetry and observability pipelines for fielded devices.
