The opportunity

Our client is a profitable, well-established business who require an experienced financial modeller who has strong FP &A experience, to build a long-term planning model.

This is a hands-on build, done side by side with the Head of FP&A and with regular interaction with the FD. You'll work together day to day, and you'll be trusted to challenge assumptions and help shape the design as you go.

The role

You'll build a clean, straightforward, fully working planning model in Excel, following an agreed design and set of drivers, and adopting the team's preferred build approach. The aim is a simple, well-structured tool that the FP&A team can pick up and run independently once complete.

The first working version is needed within the first 4-6 weeks, with the remaining time spent stress-testing, refining and handing over.

What you'll be delivering

• A fully integrated group planning model in Excel, linking the P&L, balance sheet and cash flow
• A revenue forecast built from underlying customer activity, flexible by segment
• A cost base tied to operational drivers, from headcount and contractors through to software and variable spend
• A workforce planning tool for modelling salaries and hiring plans
• A scenario, sensitivity and version control framework so the team can compare cases with confidence
• Clear, board-ready outputs, including EBITDA bridges and KPI dashboards

How you'll work

• Build the model in close partnership with the Head of FP&A, with very regular design and progress reviews
• Test the logic as you go, and call out anything unclear or likely to fail under different scenarios
• Keep the model as simple as it can be while still doing the job
• Escalate problems early rather than quietly working around them
• Stress-test the model to show which assumptions its results depend on most
• Leave the FP&A team fully equipped, with clear documentation and a hands-on training session

About you

• An expert Finance Excel modeller who builds clean, well-structured models to best-practice standards
• A strong FP&A background, with experience of integrated three-statement planning
• A collaborative style: you're comfortable working closely with the client, following a set approach, and challenging constructively when something doesn't add up
• Proven experience of stress-testing models and pinpointing the drivers that matter most
• Experience forecasting revenue from customer volumes and activity data would be an advantage
• Someone who delivers at pace and stays rigorous when the picture is unclear
