What do you mean by RTE & STE?
The Train Release Engineer (RTE) is the manager and trainer of the Agile Release Train (ART). The main task of RTE is to facilitate ART events and processes and support the team in creating value.
RTE communicates with stakeholders, raises barriers, helps risk management, and leads to continuous improvement. Solution Train (STE) Engineers are Solution Train leaders and trainers and facilitate and guide the work of all ART and suppliers in Flow Value.

Although Agile Release Trains (ART) and Solution Trains consist of self-organizing and managing teams, trains do not run or run on autopilot. That responsibility rests with the RTE, which acts most effectively as a servant leader.
You have a good understanding of the scaling of Lean and Agile practices, and understand the unique opportunities and challenges associated with nurturing and continuously aligning large development programs.
RTE and STE facilitate ART and solution training processes and implementation. They raise barriers, manage risk, add value, and contribute to tireless improvement.
Many of them are also involved in lean-agile transformation, training managers, teams, and Scrum Masters in new processes and settings. They help configure SAFe according to the needs of the organization, to standardize and document practices.
