The Sr. HR Business Process Optimization Specialist serves as an internal process consultant to HR functions across the organization. This is not an operational execution role - it is an advisory and enablement role.

• Surface systemic themes and patterns across HR functions to inform HUB prioritization and strategic planning.

• Strong facilitation skills; ability to guide cross-functional stakeholders through ambiguity and drive to clear, actionable outcomes.
• Experience designing process governance frameworks and controls in a way that is practical and adoptable by operational teams.
