FP&A Business Partner (Commercial) - 12m FTC

JMAN Group is a fast-growing data engineering & data science consultancy. We work primarily with Private Equity Funds and their Portfolio Companies to create commercial value using Data & Artificial Intelligence. In addition, we also work with growth businesses, large corporates, multinationals, and charities. We are headquartered in London with offices in New York, London and Chennai. Our team of over 600 people is a unique blend of individuals with skills across commercial consulting, data science and software engineering.

Purpose of the role: This is a 12-month fixed term contract, deliberately structured to bring experienced commercial finance capability into JMAN Group at a critical point in its growth. The purpose of this role is twofold:

• To establish a best-in-class commercial business partnering model (developing on what is already in place) across all five commercial business units from day one.
• To leave behind the frameworks, ways of working, and institutional knowledge that will make the permanent structure, whatever form it takes, immediately effective.

What this role is – and isn’t: This role is the Finance voice in commercial conversations across all five business units. The FP&A Manager – Revenue, Compliance & Systems (FP&A Manager-RCS), owns the integrity of the underlying data, systems, and revenue analysis that powers those conversations. Both roles report to the Head of FP&A and are essential and complementary. You will not own revenue recognition, ERP configuration, or audit relationships — those sit with the FP&A Manager-RCS, who provides the analytical foundation your business unit conversations are built on. Your role is to be the Finance voice in those conversations — prepared, credible, and commercially sharp — and to own the Finance relationship and all Finance follow-up with each business unit. Your focus is on being genuinely embedded across all five business units: helping business unit leads understand their performance, forecast with confidence, and make smarter commercial decisions. When data quality issues arise, you elevate to the FP&A Manager-RCS rather than resolve them yourself.

We’re looking for someone who has done this before — an experienced commercial finance professional who can hit the ground running, build trusted relationships with business unit leads quickly, and bring the confidence and credibility that comes from having operated at this level in a comparable business. You will work closely with the Head of FP&A and the FP&A Manager-RCS, and your experience will actively shape how this function develops. This role reports to the Head of FP&A and works in close support of the Commercial Partner.

Your key responsibilities:

• Dedicated business unit business partnering: Act as the assigned Finance partner for specific business units, developing deep familiarity with their clients, project types, resource profiles, and commercial drivers. Attend key business unit meetings to understand the operational context behind financial performance — not just to report on it. Build trusted relationships with business unit leads so that Finance is consulted early on in commercial decisions, not informed after the fact.
• Commercial driver analysis: Go beyond P&L reporting to understand the commercial drivers behind each business unit’s performance: client mix, utilisation, rate realisation, project margin, revenue model, and pipeline conversion. Identify and articulate the two or three key commercial levers for each business unit and track them consistently. Model the financial impact of resourcing, pricing, and delivery decisions to support business unit leads in evaluating options. Support the Head of FP&A and CFO with commercial questions on contracting and scoping — including margin analysis on new engagements, rate and pricing assumptions, and financial evaluation of contract terms.
• Forecasting, budgeting, and reforecast cycle: Partner with business unit leads and project managers to produce accurate, rolling forecasts at project and business unit level. Monitor project financial health proactively, flagging risks to margin or revenue recognition early enough for the business to act. Provide clean, timely forecast inputs and narrative commentary to support the monthly close cycle. Own the annual budget cycle end-to-end: coordinating inputs from business unit leads and Operations, consolidating assumptions, challenging submissions for commercial rigour, and delivering a final budget pack to the Head of FP&A and Commercial Partner on schedule. Lead the reforecast cycle, producing updated full-year projections at agreed intervals throughout the year.
• Business unit P&L reporting: Own the ongoing production and continuous improvement of business unit P&L reporting for monthly management packs. Present performance with clear narrative: what happened, why it happened, and what it means going forward. Work with the FP&A Manager‑RCS to ensure the underlying data feeding business unit reports is accurate and consistently defined.
• Timesheet and operational compliance: Drive timesheet compliance within assigned business units through proactive engagement with leads and project managers. Produce and distribute weekly Timesheet Compliance & Accuracy Reports, escalating persistent issues through the appropriate channel. Connect compliance data to margin reporting so that business unit leads can see the direct financial impact of late or inaccurate timesheets.
• Senior finance support: Support the Head of FP&A and CFO with business unit-level input for board and investor reporting and commercial reviews. Flag emerging commercial risks or opportunities from business unit activity that warrant Head of FP&A or CFO attention. Contribute to cross‑business unit analysis and benchmarking when requested by Finance leadership.

Requirements: Current right to work in the UK. c. 8+ years relevant experience in commercial finance, FP&A, or business partnering, with a meaningful portion in a lead role. Ideally from consulting, professional services, or a PE-backed business and within a fast‑paced and high‑growth environment. Preferred qualifications: CIMA, ACCA or ACA. Natural relationship‑builder who earns trust quickly with non‑finance stakeholders. Strong commercial instinct: able to identify what matters in a set of numbers and explain it clearly. Comfortable operating with autonomy within assigned business units while staying closely aligned with Finance leadership. Excellent communication skills — confident presenting to business unit leads and contributing to senior leadership discussions. Strong Excel skills essential. Power Query and BI tools highly desirable. Proactive and solutions‑oriented that brings answers, not just questions, and is willing to share experience openly to build capability in the team around them. Able to handle a broad range of tasks and prioritise effectively. Proactive and sees challenges as opportunities. Displays a high level of self‑awareness and takes ownership for personal development.
