What is one primary responsibility of a Release Train Engineer?

The Release Train Engineer (RTE) is a servant leader and coach for the Agile Release Train (ART). One of the primary responsibilities of an RTE is to manage and optimize the flow of value through the ART1. This involves facilitating ART events and processes, assisting teams in delivering value, communicating with stakeholders, escalating impediments, helping manage risk, and driving relentless improvement1. The RTE uses various tools, such as the Program Kanban and other information radiators, to manage and optimize this flow. They also establish and communicate the annual calendars for Iterations and Program Increments (PIs), facilitate PI Planning readiness, and assist in tracking the execution of features and capabilities1.
