Sr. Data Analyst
About The Position
You will be the analytics point of contact for Criteo's largest Performance Media clients in the Americas. You'll turn campaign and performance data into business reviews, custom analyses, A/B tests, and forecasts that senior client stakeholders act on — and when a large client's campaign is underdelivering or behaving unexpectedly, you're the person who will diagnoses why under time pressure. The work is largely self-directed. You'll own a portfolio of Criteo's largest US clients — a book of business you're accountable for end to end, not a queue of pre-scoped requests. Success in this role depends on three things: deep knowledge of how performance advertising actually works; the judgment to frame an ambiguous problem, select the right analytical method, and stand behind your conclusions when challenged; and the commercial instinct to proactively identify growth opportunities within your accounts — surfacing data-backed recommendations that clients haven't yet thought to ask for and persuading them into actions that move budgets and improve outcomes.
Requirements
- 3+ years in a client-facing or commercial analytics role within digital advertising
- SQL and Python proficiency sufficient to extract, automate, and analyze data independently from day one — this is not a skill you'll learn here
- Working knowledge of advertising measurement methodologies: incrementality, attribution, and media mix modeling
- A strong grasp of how campaigns are built, delivered, optimized, and measured — enough to diagnose problems quickly, not just describe them
- A track record of delivering analyses and recommendations directly to senior client stakeholders
- Able to work independently in ambiguous situations: you scope the problem, pick the approach, and surface trade-offs without waiting for direction
- A genuine willingness to make the people around you better: as a senior member of the team, you'll be expected to coach junior colleagues and help on their client work, not only your own
- Native or professional-level English fluency
Nice To Haves
- A bachelor's degree in a quantitative field, or equivalent practical experience (a plus)
- Experience with AI-assisted development and tooling (a plus)
Responsibilities
- Own the analytics relationship for a portfolio of Criteo's largest US clients
- Partner with commercial teams to build and deliver Client Business Reviews, custom analyses, optimization recommendations, media plans, and forecasts

- Diagnose campaign delivery and performance issues in time-sensitive, high-stakes situations
- Work with Product Analytics on performance-improving initiatives, and feed client needs into the product roadmap
- Use the Global Client Operations Center to automate or delegate repeatable work so your time goes to higher-value analysis
- Build deep expertise in a key growth area of the business and share it — through knowledge transfer and reusable client-facing collateral
- Contribute to a team where people help each other — coaching junior colleagues on analytical approach and pitching in on their client problems, as others will on yours
