Senior Investment Manager

The Group Investment Management (GIM) team is hiring a Senior Investment Manager to play a critical role in how the Group allocates, reports on, and optimises its ongoing investment allocations. This role requires strong financial acumen, the ability to work with complex data sets, and the confidence to propose capital allocation decisions to senior executives. This role will lead key elements of monthly reporting, forecasting improvements, capital redeployment, and cross‑functional alignment with divisions, Finance, Strategy and Procurement. You will also work closely with our Tooling & Dashboard teams to ensure the delivery community has the tools and processes needed to manage the change portfolio effectively.

WHAT YOU'LL BE DOING

• Capex Reporting & Financial Governance
  • Own Group reporting across budgets, forecasts, growth tracking, and acceleration updates.
  • Drive adoption and consistent use of the Group PPM tooling across divisions.
  • Run monthly data sessions with Divisions, issuing actions to resolve variances or data issues.
  • Monitor the phasing of investments, drawing insights on delivery pace, risk, and opportunities to reclaim capital.
  • Scrutinise spend feasibility and proactively recoup capital for reinvestment where appropriate.
  • Ensure adherence to financial controls including Clarity usage, change control, resourcing adoption, and detailed third‑party spend forecasting.
• Capital Redeployment & Growth Opportunities
  • Maintain a pipeline of investment opportunities that can be funded if capital becomes available.
  • Work with divisions and Procurement to identify opportunities for acceleration and cost optimisation.
  • Support Growth Fund assessment by providing high‑quality analysis and spend feasibility inputs.
• Forecasting, Tooling & Process Improvement
  • Mature the Group’s forecasting capabilities and improve budget tracking processes.
  • Partner with the Dashboard/PPM Tooling teams to enhance forecasting, budgeting and cost tooling — improving ease of use and MI quality.
  • Work with divisional stakeholders to embed improved processes and data standards across the portfolio.
• Investment Planning
  • Support the annual Investment Planning cycle with data‑driven analysis.
  • Champion the continued full adoption of the PPM tooling solution (Clarity) for cost, benefits, outcomes, OKRs and investment baselines.
  • Collaborate with senior stakeholders to gather feedback, refine processes, and support Group‑level decision‑making.
  • Ensure alignment across PPM tooling, PowerBI dashboards, and the Group’s investment approach.

WHAT YOU'LL BRING

• Experience in a Group or Enterprise‑level role owning central processes and tools.
• Proven background in capital planning, portfolio management or financial governance.
• Strong analytical capability, including advanced Excel and the ability to interpret large data sets.
• Ability to influence and drive action through data‑led insight (without direct authority).
• Excellent relationship management and communication skills, able to persuade senior stakeholders.
• Experience working with enterprise tooling such as Clarity, Planview, or similar PPM/portfolio systems.
• Experience balancing competing priorities in a fast‑paced environment.
• Demonstrated ability to design and operationalise processes at scale.

NICE TO HAVE

• Familiarity with Oracle ERP, Workday or equivalent financial systems.
• Experience working with or alongside programme delivery teams (though this is not a delivery role).
• Understanding of investment letters, baseline management, and centralised financial controls.
• Experience with PowerBI or similar analytics tooling.
