• Lead solution design and architecture for Workday and connected HR technologies, ensuring secure, scalable, and compliant end-to-end processes and data flows.
• Guide major transformation initiatives (e.g., job architecture, colleague AI, people analytics, payroll simplification) and ensure Workday effectively enables these programs.
• Align the Workday roadmap and releases: evaluate new functionality, lead impact assessments, prioritize improvements, and ensure smooth deployment and change management.
