## About the role

The Expert Engineer on the OTA Services team is the technical anchor for how NodeZero updates itself across thousands of customer deployments — without customer intervention, without downtime, and without introducing new vulnerabilities in the process. NodeZero runs as a container inside customer infrastructure. When a new image is ready, the OTA system has to find every deployed instance, negotiate the update, deliver it safely, validate it, and roll back gracefully if something goes wrong. Found on 1752vc Careers, the job board for startup and VC roles.
