The ideal candidate combines a strong software-engineering foundation with advanced Linux, scripting, cloud, container, CI/CD, and configuration-management experience. This role requires broad technical judgment, ownership of integration approaches within the assigned environment, and the ability to guide teams through complex problems affecting program readiness, stability, and delivery.
