Your mission is to turn our financial and operational data into a reliable single source of truth — and into decisions. Concretely, you steer the Group's profitability, sharpen resource allocation and equip our leaders to make data-driven calls across a fast-scaling, multi-entity and international AdTech group. You don't just report the numbers: you own a scope, challenge the assumptions behind them, and act on what they reveal. Responsibilities: Closing, Reporting & Data Reliability Co-drive the monthly and annual closing hand-in-hand with the accounting team; own the FP&A side of the timeline and its quality. Produce the monthly management reporting — Group and product-line P&L, KPI tracking, margin and cash bridges — clear, structured and synthetic. Guarantee the reliability of the numbers: reconcile finance vs. operational sources, build the single source of truth, and always trace data to its exact source before it is shared. Budgeting & Forecasting Drive the annual budget and the reforecast cycles in direct collaboration with department and division heads. Build, own and continuously improve the financial model and the rolling forecast (revenue, opex, headcount, cash). Turn business assumptions into figures and challenge them — no black boxes. Profitability & Performance Analysis Run profitability analysis by product line, entity, project and business line — including publisher rev-share economics and SaaS / CMP recurring revenue. Track and challenge operating costs; identify and size optimisation levers (Pareto: the 20% of costs or initiatives driving 80% of the impact). Build and maintain the performance dashboards leaders actually use to steer. Business Partnering & Decision Support Partner with operational managers: help them monitor their budgets, read their performance and act on it. Deliver ad-hoc studies and business cases for the CFO and top management (pricing, investment / capex, hiring ROI, new-market or new-product cases). Make finance actionable: translate analysis into a clear recommendation and a decision, up and down. Tools, Process & Continuous Improvement Proactively improve the FP&A tooling and processes (PDCA) — standardise, document and automate recurring reporting without creating legacy. Contribute actively to the implementation of new tools (BI, ERP): requirements, testing and adoption. Set the analytical standards a growing finance team can scale on; act as FP&A reference and mentor for more junior profiles. Your profile for this job Candidate prerequisites Must have Master's (Bac+5) in Finance, Management Control or Audit (Business School / University). 4–6 years' successful experience in FP&A / management control — corporate environment or audit firm (Big 4 a plus). Advanced Google Sheets / Excel: modelling, pivot tables, advanced functions. Solid general and cost accounting. Professional English, written and spoken. Rigour, analytical mindset, ability to synthesise, autonomy and proactivity. Should have Hands-on ERP experience (SAP, Oracle, MS Dynamics, NetSuite…). BI tool experience (Power BI, Tableau, Looker). Demonstrated business-partnering track record with non-finance stakeholders. Your mind set to share our adventure 🚀 You want to make an impact and move things forward collectively. Does hearing phrases like "Yes, but we've been doing it this way for years..." make your hair stand on end? We feel the same way: progress is made by questioning what already exists. 🧠 You solve problems pragmatically and analytically. 🏃‍♂️ You're looking for a fast-moving environment where your agility will be an asset. The 80-20 (Pareto) principle holds no secrets for you. 🎧 Your ability to listen encourages you to challenge and improve yourself on an ongoing basis. Benefits & Work Environment 🌍 Dynamic Remote Culture: At Sparteo, we embrace a flexible work environment that adapts to your lifestyle, allowing you to contribute from wherever you feel most productive, be it from home or our urban offices in Paris, Lille, or London. 👥 Close-knit Team: Be part of our dynamic and united team, where collaboration, innovation, and mutual support drive our collective success and create a thriving work environment. 🎉 Vibrant Social Events: Engage in regular social gatherings and company events that foster community and celebrate our milestones. 🚀 Rapid Growth: Experience the excitement of working with a company in rapid expansion mode, impacting the advertising technology landscape across Europe and beyond. 📈 Tailored Support: We provide robust career development support, including training programs, career check-ins with HR, opportunities for internal mobility, and performance feedback sessions conducted quarterly or semi-annually, depending on your role. 🌴 RTT Days: We support work-life balance with additional rest days (RTT), provided based on position and tenure, empowering you to recharge and enjoy life outside of work. 🩺 Comprehensive Health and pension plans: We provide a robust health benefits plan, ensuring you and your family are covered and cared for. 💼 Additional Perks: 🍽️ Benefit from the Swile card for meals. 🚆 Partial reimbursement of public transit passes.
