Join us as a Staff Data Analyst – Growth to own how Qonto measures whether its marketing spend actually works. You'll take charge of our attribution models and incrementality tests — geo tests, conversion lift studies — turning marketing spend across channels into evidence-backed decisions, under the guidance of Clotilde Pety , our Lead Data Analyst. ➡️ What you'll do • Own attribution, end to end — maintain the attribution models and touchpoint definitions, and be the go-to when a stakeholder asks why the numbers moved. • Test where it matters, inside the ad platforms — design and run geo tests and conversion lift studies directly in Google Ads and Meta Ads. • Build the roadmap, not just answer tickets — pick up and drive the incrementality - testing roadmap within the first few months. • Referee, don't take sides — help channel teams and Finance agree on what the numbers actually say. • Use AI across the workflow, from making sense of a stakeholder's ask to shipping the dashboard that answers it. ➡️ What we're looking for • Has owned an attribution model, not just read one — can explain last-click vs first-click and has navigated a real team disagreement over it. • Has tested incrementality inside ad platforms — geo tests or conversion lift studies in Google Ads/Meta Ads. • Adapts the message to the room — explains technical results to non-technical stakeholders, knows what's their call to make. • Self-sufficient in SQL and a BI tool (Snowflake, Tableau, or equivalent). • Uses AI as part of the workflow. ➡️ What we can offer you • Real ownership from day one — no inherited playbook, you build the roadmap. • A stack that's already there — Snowflake, Tableau, AI-forward team. • Your own lane to grow into, distinct from the senior data scientists. • Stakes that matter — your calls influence real budget allocation. ➡️ Your future manager: Your manager will be Clotilde Pety , Lead Business Analytics Growth. • Her background?
