What You’ll Be Doing

• Provide programme-level leadership and delivery oversight for a reputable utilities company.
• Act as the central integration point across multiple Agile and DevOps squads, Product Owners and Delivery Leads.
• Maintain a clear view of delivery progress, milestones, risks, dependencies and performance across the portfolio.
• Lead annual planning cycles and quarterly OKR and prioritisation exercises, ensuring delivery remains aligned with wider business objectives.

Main Skills Needed

• Strong Senior Project or Programme Management experience, ideally within a complex product-led or technology environment.
• Experience overseeing multiple delivery teams, Agile squads and Product Owners rather than managing a single project.
• Proven experience managing significant budgets, ideally in the region of £5m.
• Strong financial and commercial management skills, including forecasting, business cases and benefits tracking.
• Experience managing third-party suppliers, contracts, Statements of Work and commercial performance.
• Confident leading annual and quarterly planning cycles, portfolio prioritisation and resource planning.

• Experience in the Utilities industry is preferred, not essential.

• The opportunity to shape how multiple product teams plan, prioritise and deliver.
• Exposure to senior business stakeholders and strategic decision-making.
• A varied role combining programme leadership, commercial management and portfolio-wide planning.
