Embedded Validation & Tools Engineer - OTA
- Design, implement and execute comprehensive OTA validation plans across device families and release types (full OS images, firmware, bootloader, A/B updates, delta/patch updates).
- Build, manage and scale automated testbeds and harnesses (hardware-in-the-loop, virtualized devices, emulators) to run regression, integration, and stress tests for OTA flows.
- Implement automation for end-to-end OTA pipelines (from build artifact signing and staging to rollout and post-update verification) using Python, shell, and CI tools.
- Validate update mechanisms and components: bootloader, update agent, package formats, rollbacks, A/B partitions, and recovery modes.
- Test update resilience under adverse conditions: intermittent networks (cellular/Wi-Fi), high latency/packet loss, power interruptions, low-battery scenarios, storage constraints, and corrupted images.
- Validate security properties: signing/verification, secure transport (TLS), secure boot, key management, and vulnerability surface introduced by update components.
- Define metrics and KPIs (success rate, rollback rate, mean time to recover, time-to-update), instrument devices and cloud backends to measure rollout health, and produce reports for release readiness.
- Perform root cause analysis on failed updates, reproduce field issues, and drive remediation with firmware and backend engineering teams.
- Maintain device lab hardware (JTAG, serial consoles, network emulators, power controllers, logic analyzers) and tooling stacks (Wireshark, serial monitors, provisioning fixtures).
- Contribute to OTA process improvements: staging strategies, canary rollouts, rollback thresholds, risk assessment templates, and runbook documentation.
- Bachelor’s degree in Electrical Engineering, Computer Science, or related field (or equivalent experience).
- 5+ years of hands-on experience validating embedded devices and firmware updates (OTA or similar).
- Strong programming/scripting ability in Python and familiarity with C/C++ for embedded debugging.
- Deep understanding of embedded platforms (embedded Linux and/or RTOS), bootloaders (e.g., U-Boot), partition schemes, and A/B update models.
- Practical experience with building automated test harnesses and integrating tests into CI pipelines (Jenkins, GitLab CI, CircleCI, etc.).
- Experience with hardware debugging tools and workflows: serial/UART, JTAG/SWD, logic analyzers, oscilloscopes, power cycling rigs.
- Familiarity with networking protocols used for OTA ( MQTT, CoAP) and wireless technologies (Wi-Fi, Ethernet, cellular, BLE).
- Experience analyzing logs, packet captures, and device telemetry to diagnose update failures.
- Strong debugging skills and methodical problem solving; able to reproduce complex failure modes and propose design fixes.
- Excellent communication skills — able to write clear test plans, runbooks, and postmortems.
- Experience with cloud OTA platforms and services: AWS IoT Device Management, Mender, Azure IoT, Google Cloud IoT, or custom fleet management systems.
- Knowledge of secure update practices: code signing, public key infrastructure (PKI), TPM/secure element integration, secure boot implementations.
- Experience with CAN/LIN, automotive-grade validation, or industrial protocols for fleeted devices.
- Familiarity with containerization/virtualization for test environments (Docker, QEMU).
- Experience with large-scale rollout strategies (canary/capacity ramping, staged rollouts, feature flags).
- Firmware build systems and OS build frameworks (Yocto/OpenEmbedded, Buildroot).
- Prior experience with telemetry frameworks and analytics (Prometheus, Grafana, ELK).
- Robust health coverage. Excellent health, dental and vision insurance covered up to 100% by ALSO with FSA & HSA options.
- One Medical membership and dedicated insurance advocates.
- Rich fertility and family building benefits with Progyny.
- Flexible time off.
- 401(k) match.
