  • Managing the planning, governance and administration of BT Investment Board meetings and maintaining associated documentation and processes.
  • Building robust end-to-end financial and commercial analysis to support executive decision-making.
  • Leading pan-BT business cases where investment decisions impact multiple business units.
  • Acting as a trusted adviser to the Group CFO and wider leadership team, responding to strategic and commercial questions as they arise.
Apply
  • Providing expert guidance to stakeholders across BT on business case development, investment appraisal methodologies and governance requirements.
  • Driving consistency and continuous improvement in business case standards, templates and investment governance processes.
  • Essential Skills / Experience

    • Qualified accountant (ACA, ACCA or CIMA).
    • Experience in a commercial finance, business partnering or investment evaluation role.
    • Strong financial modelling and analytical skills, with advanced Excel capability.
    • Ability to distil complex analysis into clear insights, recommendations and senior-level communications.

    Desirable Skills / Experience

    • Excellent communication and presentation skills, with the ability to influence senior stakeholders.
    • Experience working with senior finance and non-finance stakeholders.
    • Strong commercial acumen and the ability to assess opportunities from a broader business perspective.
    • Experience operating in a complex, fast-paced and matrixed organisation.
    • Understanding of investment appraisal, business case development and governance processes.
    • Industry experience within a large, complex organisation.
