Every board has a lifecycle: it’s manufactured, provisioned, updated repeatedly in the field, and eventually retired, and it needs to remain trustworthy at every stage. The Security & Lifecycle team owns the platform’s ability to manage that lifecycle end to end. This starts at manufacturing, provisioning cryptographic keys and building the images and tooling used to bring devices into service. It continues through the vehicle’s life, safely updating software in the field, rotating and revoking keys as needed, and verifying that any code loaded onto the platform is authentic. Underneath all of this, the team owns the nonvolatile memory and storage infrastructure that makes persistence possible, including low-level storage drivers and the memory map that allocates space across every storage unit on the platform. The team collaborates closely with platform, safety, and manufacturing engineering teams, as well as with external silicon and tooling partners.
