Job Description

At Criteo, we are not just serving ads; we are defining the future of commerce media. With 20 offices worldwide and 5 billion daily impressions, our data-scale provides a unique playground for advanced analytics.

As a Senior Data Analyst in the AXSI team, you will be the bridge between complex statistical methodologies and commercial success. While this is a hands-on technical role, it requires a strategic mindset. You won’t just run tests; you will champion the truth of performance, enabling our clients to move beyond simple attribution toward true Incrementality.

Measurement & Causal Inference

  • Go beyond basic A/B testing to design, validate, and execute sophisticated incrementality tests.
  • Help clients distinguish between correlation and causation to quantify the true value of their Criteo investment.
  • Navigate complex measurement landscapes, advising on how Criteo fits within broader measurement models (e.g., Marketing Mix Modeling (MMM) or Multi-Touch Attribution (MTA)).

Incrementality Consulting

  • Partner with commercial teams to navigate the Measurement topic in our client relationships. You will translate complex experimental data into clear, compelling narratives that drive decision-making.
  • Act as a trusted advisor to clients and commercial stakeholders, moving the conversation from what happened? to what should we do next?

Innovation & Scalability

  • Leverage our data-stack (Hadoop, Vertica, Python, SQL) to build automated, scalable solutions for measurement problems.
  • Collaborate with Product and R&D teams to ensure our measurement roadmap aligns with the reality of client needs and market evolution.

Who You Are:

The Experience: You have 2+ years of experience in analytics, with some experience with measurement, experimentation, or ad-tech would be desirable.

Tech Stack: You have experience with SQL & Python, comfortable working with large datasets and automating your workflows.

Statistics: An understanding of statistical inference, you have experience with A/B testing, hypothesis testing and causal impact.

Storytelling: You have strong communication skills. You can distill complex analysis into impactful insights for non-technical business audiences.

Team Player: You are a problem-solver who thrives in a collaborative, inclusive environment and are eager to share knowledge with peers.

Diverse experiences enrich our team. Even if you don't tick every box, we want to hear from you!

We acknowledge that many candidates may not meet every single role requirement listed above. If your experience looks a little different from our requirements but you believe that you can still bring value to the role, we’d love to see your application!​

Who We Are:

Criteo is a leader in commerce media, helping brands, agencies, and publishers create meaningful consumer connections through AI-powered advertising solutions. We’re shaping a more open and sustainable digital future for advertising.

At Criteo, our culture is as unique as it is diverse. From our offices across the globe or from the comfort of home, our 3,600 Criteos collaborate together to build an open, impactful, and forward-thinking environment.

We foster a workplace where everyone is valued, and employment decisions are based solely on skills, qualifications, and business needs—never on non-job-related factors or legally protected characteristics.

What We Offer:

🏢 Ways of working – Our hybrid model blends home with in-office experiences, making space for both.
📈 Grow with us – Learning, mentorship & career development programs.
💪 Your wellbeing matters – Health benefits, wellness perks & mental health support.
🤝 A team that cares – Diverse, inclusive, and globally connected.
💸 Fair pay & perks – Attractive salary, with performance-based rewards and family-friendly policies, plus the potential for equity depending on role and level.

Additional benefits may vary depending on the country where you work and the nature of your employment with Criteo.
