• Deliver high-impact modelling and analysis using Excel and Anaplan, including scenario modelling, sensitivities, pricing and margin analysis, and investment business cases.
• Act as a trusted senior partner to the Lending Product team - challenging assumptions, translating financial complexity into commercial language, and supporting trade-off decisions.
• Provide Executive and Board-level insight, with concise narratives that link financial outcomes to underlying business drivers.
