OUR MISSION AND CUSTOMERS] We are creating the freedom for SMEs to succeed by delivering Europe's leading finance workspace with banking at its core, augmented by financial tools. Founded in 2016 and launched in 2017 by Alexandre and Steve, Qonto has grown to 1,700 Qontoers serving over 750,000 customers across 8 European countries. With 80+ nationalities, 45% women, of which 56% of women in our leadership team, diversity isn't a program; It's who we are.

We want people who experiment without waiting for permission, push AI beyond the obvious, know when to trust it, and when to question it. 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.

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. Use AI across the workflow, from making sense of a stakeholder's ask to shipping the dashboard that answers it.

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. Self-sufficient in SQL and a BI tool (Snowflake, Tableau, or equivalent).

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.

Clotilde started her career across some of the top data consultancies in France — fifty-five, Artefact, and Ekimetrics — working on data science and analytics challenges across industries. She then built and grew the Customer Insights team at Galeries Lafayette: though embedded in Marketing, the team forged strong working relationships across Strategy & Finance, Merchandising & Buying, and Operations — directions that had never partnered with an analytics team before. She joined Qonto as Lead Business Analytics Growth, partnering with Growth, Customer Lifecycle Product, and Operations Onboarding.

Clotilde leads with a relentless focus on the "why" — before any analytics request moves forward, she insists on a live conversation to nail down the context and the decision it's meant to inform (she rebuilt her team's own ticket templates around exactly this). DATA RETENTION By applying, you agree that Qonto processes your personal data to assess your application. Your data is kept for up to 2 years in our candidate pool.
