About the role

  • Staff Firmware Engineer, you will architect the next-generation, on-device Over-the-Air (OTA) update framework for our Software-Defined Vehicle (SDV) platform.
  • This is a pure firmware role focusing on high availability, extreme durability, and uncompromising backend-to-device cryptographic security natively built on the Uptane standard.

Responsibilities

  • Uptane Architecture Ownership: Lead the on-device design and implementation of an automotive-grade Uptane client framework.
  • Compromise-Resilient Security: Implement and maintain Uptane's multi-repository validation systems.
  • Metadata Role Verification: Develop low-level firmware state machines to securely parse and validate Uptane-structured cryptographic payloads, verifying signatures and thresholds across separate organizational roles (Root, Timestamp, Snapshot, and Targets).
  • Implement and maintain Uptane's multi-repository validation systems.
  • Develop low-level firmware state machines to securely parse and validate Uptane-structured cryptographic payloads, verifying signatures and thresholds across separate organizational roles (Root, Timestamp, Snapshot, and Targets).
  • Implement advanced on-device patching algorithms and delta-compression engines to maximize internal flash lifespan (eMMC, UFS, QSPI) and minimize bus bandwidth.
  • You will design the client-side embedded software responsible for safely receiving, orchestrating, and validating large-scale software updates across a distributed network of control units.

Requirements

  • All documents must be submitted in PDF format and under 30MB in size.
  • End-to-End Update Orchestration: Oversee complex vehicle-level software "bundles." Synchronize dependency tracking, resolve software compatibility matrices across multiple internal networks, and ensure atomic execution during the flashing cycle.
  • On-Device & Cloud Integration: Act as the core technical bridge to the Cloud/Infrastructure team.
  • Co-design optimal edge-to-cloud interfaces, secure time-attestation protocols, vehicle version manifests, and custom Uptane transport layer profiles (POUFs).

Nice to have

  • Deterministic Firmware Development: Write high-performance, safety-critical code using C for bare-metal systems, custom bootloaders, and RTOS kernels.
  • Utilize Python exclusively for host-side tooling, secure payload wrapping.

Compensation

  • $189,240 - $266,760
