FP&A Manager

proSapient
London

Every day, somewhere in the world, important decisions are made. Whether it is a private equity company deciding to invest millions into a business or a large corporation implementing a new strategic direction, these decisions impact employees, customers, and other stakeholders. 

Consulting and private equity firms come to proSapient when they need to discover knowledge to help them make great decisions and succeed in their goals. It is our mission to support them in their discovery of knowledge. 

We help our clients find industry experts who can provide their knowledge via interview or survey: we curate this knowledge in a market-leading software platform; and we help clients surface knowledge they already have through expansive knowledge management.

We’re hiring our first FP&A Manager, reporting directly to our Finance Director. As we continue to grow, so do our forecasting, budgeting, and commercial business partnering needs. This is a rare opportunity to own and drive a financial model from the ground up, underpinning short term and multi-year planning and giving leadership and the board real confidence in where we’re headed. 

The role will play a key part in the company’s overall success - providing insight and control over the company’s financial plans and performance and building new financial capabilities and analysis to support management and commercial decision-making. You’ll work closely with the Finance Director, CFO and other business leaders to help shape the future of the business. 

 

Key duties in this role will include: 

Budgeting, Forecasting and Planning 

  • Take full ownership of the current forecast model, ensuring that it remains fit for purpose as the business scales, and modifying or upgrading as appropriate 
  • Build and monitor the company’s financial forecast (P&L and cash flow) – both in-year and multi-year 
  • Design and manage the annual budgeting process across the business 
  • Introduce and manage budget allocation frameworks to empower teams and drive accountability 
  • Lead scenario analysis and support strategic projects with robust financial modelling 

Headcount Planning & Resource Optimisation 

  • Partner with the business to enhance workforce planning and monitoring across the company, especially within client services, our largest function. 
  • Work with operational leaders to ensure headcount scales efficiently with demand.

Commercial Insight & Business Partnering 

  • Provide financial input into commercial strategy and investment decisions, including pricing, sales targeting, technology investment allocation and market opportunities. 
  • Provide effective business partnering and analysis, ensuring finance is a trusted voice in operational decisions 

Performance Management 

  • Partner with Business Operations and other functions to ensure that financial plans are supported by relevant KPIs which are tracked and managed
  • Preparation of materials for the Board pack 
  • Deliver regular management reporting for the ELT and variance analysis with actionable insights 

 

Requirements

  • ACA/ACCA/CIMA qualification or equivalent 
  • Strong, relevant experience in FP&A roles 
  • Expertise in building and maintaining highly robust financial models (particularly integrated P&L, balance sheet, and cash flow) 
  • Highly proficient in MS Excel and Powerpoint. Previous Tableau experience would be an advantage.
  • Experience with workforce planning and headcount forecasting, particularly in people-heavy operating models 
  • A strategic thinker who enjoys getting into the detail 
  • Commercial curiosity and ability to translate operational drivers into financial plans 
  • Able to interpret and explain complex information to non-finance leaders and teams, and to influence decisions 
  • Comfortable operating without direct reports but confident in driving cross-functional processes 
  • Ability to manage multiple priorities and work in a fast-paced, dynamic environment 

Benefits

What we can offer you: 

  • Tenure Gifts - Vouchers, extra holiday and sabbaticals for each year of employment. 
  • Enjoy the flexibility of working remotely for up to 20 days each year, allowing you to tailor your work environment to your needs and embrace a change of scenery. 
  • Employee Assistance Programme - Access to a health and wellbeing service that offers personalised advice and support from specialist teams. 
  • Enhanced Maternity & Paternity pay. 
  • Annual Leave - 25 days + bank holidays which includes a week's closure over the Christmas period to fully reset.
