Present architecture roadmaps, trade‐offs, and impact assessments to executive stakeholders. Represent MBNL in external forums, vendor strategy sessions, and industry groups, influencing direction and sharing insight.
• Leadership & Culture Act as a role model for the MBNL Behaviours—questioning the status quo, building trust, and driving continuous improvement. Coach and support managers and leaders, embedding architectural thinking and constructive feedback into everyday ways of working. Develop people to shine—raising architectural maturity across the organisation.

Who we're looking for: Significant experience (typically 10+ years) as an Enterprise Architect, ideally in telecommunications or similarly complex environments.
