Senior Manager GTM Effectiveness Strategic Portfolio Management

The GTM Effectiveness Portfolio Manager supports the operational governance, planning, and executive visibility of the GTM Effectiveness transformation portfolio. The role enables disciplined demand intake, business case validation, prioritisation, quarterly planning, capacity planning, and portfolio health management to ensure the right work is assessed, sequenced, funded, and delivered against strategic GTM priorities.

The role does not manage individual project governance forums, which remain the responsibility of Project Managers and delivery leads. Instead, it provides portfolio-level oversight across GTM Effectiveness to ensure demand is proactively managed, dependencies and capacity impacts are visible, funding requirements are understood, business cases are validated, and portfolio decisions are supported by clear, consistent data.

The role requires strong organisational discipline, attention to detail, confidence to challenge priorities and governance standards where required, and the ability to provide concise executive portfolio reporting to senior stakeholders. It plays a critical role in creating transparency, improving decision quality, and enabling GTM Effectiveness to deliver transformation outcomes with pace, accountability, and operational rigour.
