About the Role

Support strategic planning, investment decisions, and transformation initiatives through clear, accurate, and traceable architectural views. Enable effective use of the architecture repository by defining modelling patterns, guidance, and best practice for the wider architecture community. Contribute to architecture governance forums, providing expert guidance and influencing key stakeholders across the organisation.
