Senior Data Analyst

What You'll Do:

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.
