Role Overview 

The Portfolio Manager, Cross Platform Delivery (CPD) sits within GI Headquarters as part of a GI level Portfolio and Financial Center of Excellence (COE). The role partners with GI Finance, CPD, and GI senior leaders to strengthen enterprise portfolio governance, planning integrity, and investment decision making across GI. 

This is a high leverage GI HQ enablement role, not a product or domain portfolio owner. You will synthesize financial and delivery signals into forward looking insights, scenarios, and decision tradeoffs that help GI leadership allocate investment, manage constraints, and adjust course. The role connects strategy to execution through disciplined planning integration (LRP, annual, and in year), GI HQ reconciliation rhythms, a executive ready narratives that improve the speed and confidence of GI decisions. 

How will you make an impact in this role?

• Own the monthly GI HQ reconciliation cycle, reconciling plan vs. actuals/forecast, investment changes, and delivery signals; explaining drivers and variances; and producing a single, trusted GI narrative for leadership consumption. 
   
• Enable leadership decisions by translating complex portfolio data into executive ready insights: clear storylines, options, tradeoffs, and recommendations aligned to GI strategy. 
   
• Proactively structure GI Long Range Planning (LRP) and annual planning submissions—building the investment architecture, assumptions framework, and traceability required for GI leadership decisions (including support for enterprise efficiency/REE efforts as needed). 
   
• Build and maintain GI macrolevel scenario models (what if, sensitivities, constraints) to inform GI leadership tradeoffs across cost, capacity, and risk, quantifying second order impacts and defining decision guardrails (e.g., efficiency/REE scenarios). 
   
• Drive cross GI alignment of financial and portfolio inputs so GI plans are intern
