Senior FP&A Manager
Isio is expanding its commercial finance capability, building out the Finance Business Partnering and FP&A teams that support the Group. The Senior FP&A Manager role is a senior appointment within FP&A and the analytical engine of the Group, owning the planning architecture: the budget and three-year plan, the models behind them, the consolidation and challenge of business unit submissions, and the financial content that reaches the Executive Committee, the Board, our lenders and our private equity shareholder.
Where our Finance Business Partners work with the business units, this role holds the centre. It sets the definitions, owns the calendar, quality-controls what comes in, and deputises for the Director of Financial Performance at Executive level. It suits someone who has built this discipline before, ideally in a private equity backed environment, and who wants the scope to shape how a growing group plans and reports on itself.
What does the role entail?
Group Planning & the Three-Year Plan
Own the Group budgeting process end to end: calendar, templates, assumptions, consolidation and sign-off pack.
Build and maintain a robust three year plan, including the integrated cashflow model, and keep it genuinely driver-based rather than extrapolated.
Own the financial figures underpinning the Value Creation Plan, and the tracking of delivery against it.
Consolidate, review and constructively challenge business unit budgets and forecasts before they reach the Executive.
Lead scenario modelling, sensitivity analysis and capacity planning across the plan period.
Board, Executive, Lender & Shareholder Reporting
Own the financial content within Board, Executive Committee, lender and shareholder reporting: exhibits, narrative, quality and timetable.
Build and maintain the standard analytical set: EBITDA and variance bridges, contribution and margin analysis, LTM and run-rate views, cash and covenant metrics.
Translate a complex multi-business-unit performance picture into a clear, decision-ready story for a senior external audience.
Support the Director of Financial Performance as a point of contact for shareholder queries on financial performance.
Standards, Definitions & Assurance
Act as the arbiter of financial definitions and methodology across the Group, so that numbers reconcile wherever they surface.
Quality-control business unit submissions and commentary, providing consistency and challenge before publication.
Resolve the root causes of recurring inconsistency rather than reconciling the same differences each month.
Proactively manage the finance calendar, particularly the strategy, target and budget cycle.
Data, Analytics & Management Information
Own the Group KPI and MI reporting suite in Power BI, including the underlying data logic and its integrity.
Work with the wider finance team to develop the Kimble professional services automation platform and realise more of its value.
Support the commercial development of the Group data warehouse, shaping it toward genuine decision-making use cases.
Drive automation and simplification so the team spends materially more time on analysis and less on assembly.
Leadership
Deputise for the Director of Financial Performance, including at Executive and shareholder level.
Manage, develop and stretch the FP&A Analyst.
Set the analytical standard for the wider Business Partnering and FP&A team, and coach to it.
What we’re looking for?
Required Experience
Fully qualified accountant (ACA / ACCA / CIMA or equivalent) with significant post-qualified experience in FP&A or commercial finance.
Demonstrable ownership of a full budget and forecast cycle in a multi-business-unit organisation.
Track record of producing Board or investor-grade reporting, with the judgement to know what a senior audience needs and what it does not.
Strong financial modelling capability, including integrated P&L, balance sheet and cashflow.
Experience in a private equity backed business is strongly preferred: shareholder reporting, value creation plan tracking, lender or covenant reporting, or supporting a quality of earnings exercise.
Professional services or consulting economics (utilisation, rate realisation, recovery, WIP and lock-up) is an advantage.
Line management experience, or clear readiness for it.
Skills & Competencies
Fluent in building and defending an EBITDA bridge.
Advanced Excel; strong working knowledge of Power BI and the discipline of a well-structured data model.
Credibility and confidence to challenge senior stakeholders constructively, including peers closer to the business than you are.
Comfortable operating at pace with imperfect data and firm deadlines.
An enquiring mind, seeking to improve processes and automate reporting.
Evidence of having raised the standard of an existing team or process, not simply operated one.
