FP&A Lead

ABOUT US Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE As FP&A Lead, you take ownership of group FP&A at a moment of rapid growth, with a remit that spans reporting, modelling, planning, systems and a team. You build the architecture of a finance function that is still being defined, rather than inheriting one. You are the reference point for numbers and analysis for the board, investors, lenders and ExCo, turning complex multi-entity data into clear decisions. You lead the FP&A team and set its roadmap, from quick wins to long-term objectives. RESPONSIBILITIES - Own group reporting to the board, investors and third parties, including the quarterly board pack and monthly investor update. - Build tailored models and figures for lenders, prospective investors and advisors. - Architect the financial model as one source with several scenarios, plus the runway and cash burn model with Treasury. - Orchestrate the end-to-end planning cycle: budget, reforecast, challenge, consolidation and the long-term business plan. - Provide management control across the group’s entities as one of the functional counterparts of regional finance managers. - Structure the finance data foundation: ERP data and processes, entity rollout, close and reporting automation, KPI framework and FP&A calendar. - Embed AI into FP&A workflows (analysis, reporting, forecasting and close automation), within the Group’s data security framework. - Model strategic scenarios such as new countries, M&A and cross-perimeter arbitrations. - Lead and develop the FP&A team, and build its roadmap in alignment with the wider finance roadmap. CANDIDATE REQUIREMENTS - 10+ years of experience in FP&A or finance leadership, including team management. - Track record of building and owning a board-grade financial model with several scenarios. - Experience running budget and reforecast cycles in a multi-entity, multi-currency environment. - Comfort with ERP-driven reporting and automation. - Hands-on use of AI in finance work (LLM-assisted analysis, modelling support, reporting automation), with the rigor to verify outputs and the ability to drive adoption across a team. - Credibility with investors and lenders, and the ability to turn numbers into a narrative for an ExCo. - Background in scale-ups or late-stage tech, or in industrial, aerospace or defense groups with contract-based economics. - Hands-on, structured and rigorous, at ease in a high-growth, ambiguous setting. - Strong quantitative or finance background (engineering school, business school or equivalent) preferred; track record weighs more than the diploma. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
