The Release Train Engineer (RTE) is a servant leader and coach for the Agile Release Train (ART), which is a group of Agile teams that work together to deliver value. The RTE facilitates the ART events and processes, and supports the teams in delivering value. They communicate with stakeholders, escalate impediments, help manage risk, and drive relentless improvement. The RTE also serves as the Scrum Master for the ART, which means they help the teams apply and improve the Scrum practices, such as planning, reviewing, and retrospecting. The RTE is not the technical leader, the content authority, or the program manager of the ART, but rather the facilitator and enabler of the ART’s success. References: Release Train Engineer - Scaled Agile Framework, Release Train Engineer (RTE): Responsibilities and Skills | Indeed.com
