What is the role of the System Architect/Engineer?

The role of the System Architect/Engineer in SAFe is to guide the teams and support the Architectural Runway, which is the existing code, components, and technical infrastructure needed to implement near-term features without excessive redesign and delay. The System Architect/Engineer defines and communicates the technical and architectural vision for the solutions developed by an Agile Release Train (ART), ensuring that they fit the intended purpose and align with the enterprise and solution architecture. The System Architect/Engineer also collaborates with various roles, teams, and stakeholders within and outside the ART to ensure that the system architecture supports the evolving business needs and enables fast and reliable implementation. References: System Architect/Engineering - Scaled Agile Framework, Architectural Runway - Scaled Agile Framework
