Join us as a Product Manager to build the accounting products that will make Qonto the default finance workspace for SMEs across Germany and beyond. You'll own our accounting expansion in the German market end-to-end — shaping the product strategy, deepening our local offering, and defining what we build next — in one of the most fragmented and locally complex domains in fintech: German accounting, bookkeeping, and the DATEV ecosystem. You will report to Paul Mourot, Head of Product for Accounting. ➡️ What you'll do Own your product roadmap end-to-end: Define what we build, why, and in what order — working with engineers, designers, and domain experts to ship features that make a real difference for SMEs and their accountants in Germany. Go deep on German accounting workflows and develop a sharp understanding of how accounting actually works in Germany. Define and execute the German accounting strategy by understanding customer needs, evaluating what to build vs. partner on, and shaping an offer that's genuinely useful to German SMEs, not just a localized version of what works elsewhere. Ship faster with AI: Use AI tools (Dust, Notion AI, Claude) and leverage AI as a product lever, identifying where automation and intelligence can transform accounting from a chore into a competitive advantage. Challenge the status quo: Question assumptions, prototype fast, and push for the best possible product. Work with maximum squad autonomy: Your squad owns its roadmap, picks its approaches, and ships independently. No layers of approval, no waiting on committees. ➡️ What we're looking for Deep German accounting domain expertise as you've worked at or closely with a German accounting-tech company. 5+ years as a Product Manager: Concrete examples of products you took from 0 to 1 or significantly scaled. You think in outcomes, not features, and you're comfortable making hard trade-offs. AI-native workflow: You use AI to supercharge how you work — from research and analysis to sp
