Job Summary

Architect and lead the on-device Over-the-Air (OTA) update framework for a software-defined vehicle platform, using Uptane-based security to enable zero-downtime, compromise-resilient updates. Design embedded firmware that securely receives, orchestrates, and validates large-scale software bundles across distributed control units. Serve as the core technical bridge to cloud/infrastructure teams, co-designing edge-to-cloud interfaces, time-attestation, and vehicle version manifests.

Location: Sunnyvale, San Francisco

Workplace: Onsite

Employment Type: Full time

Job Function: Hardware, Embedded & Systems Engineering

Seniority: Mid level

Key Responsibilities

•Own the on-device design and implementation of an automotive-grade Uptane client framework.
•Establish distinct verification paths for Primary ECUs (security gateways) and resource-constrained Secondary ECUs.
•Implement and maintain Uptane multi-repository validation to secure the in-vehicle delivery pipeline against key compromise and mix-and-match attacks.
•Develop low-level firmware state machines to securely parse and validate Uptane cryptographic payloads and verify signature thresholds across Uptane roles (Root, Timestamp, Snapshot, Targets).
•Bridge embedded vehicle subsystems with the cloud infrastructure team by co-designing secure edge-to-cloud interfaces and update-related protocols/artifacts.

Pay and Benefits

Salary: USD 189,240 - 266,760

Key Requirements

•Oversee vehicle-level software “bundles,” synchronize dependency tracking, resolve compatibility matrices, and ensure atomic flashing-cycle execution.
•Lead on-device design and implementation of an automotive-grade Uptane client framework.
•Implement and maintain Uptane multi-repository validation systems, including cryptographic verification using backend (Director) and offline-keyed asset vault (Image) approaches.
•Develop firmware state machines to securely parse and validate Uptane-structured cryptographic payloads, verifying signatures and thresholds across Root, Timestamp, Snapshot, and Targets roles.
•Co-design edge-to-cloud interfaces, secure time-attestation protocols, vehicle version manifests, and Uptane transport layer profile (POUF) support.
