• The role anticipates and manages critical drivers of scale/performance of the platforms (e.g. Account/Contact data remediation, the enterprise AI control plane spanning Azure, licensing and storage optimisation) for optimal outcomes and supports squads in adhering to WNZL’s architecture and engineering governance.
• Owns and operates the enterprise AI control plane for D365 & Power Platform - governing Copilot, agents, AI Builder, and automation capabilities across environments, with safe orchestration, identity boundaries, and risk controls.
• Engaging stakeholders - the CIO, programme sponsors, and business owners across the platform’s consuming programmes - and keeping them informed about the D365 & Power Platform technology delivery roadmap is crucial.
• The role collaborates with stakeholders across Westpac Group, Technology, business, Microsoft (as strategic vendor), and customers. It owns and manages the Microsoft D365 vendor relationship centrally - licensing, roadmap alignment, escalations, and co-innovation opportunities - and develops pathways that make interacting with the D365 & Power Platform ecosystem easy for all stakeholders, prioritising continuous improvement and feedback.
• The role actively supports squads in adhering to WNZL’s governance processes, including the Architecture Review Board and platform steering forums.
