## About the Role

* 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

 * A bachelor's degree in a quantitative field, or equivalent practical experience (a plus)

 * Experience with AI-assisted development and tooling (a plus)

## Description

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.

 * 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

 * Design, run, and interpret controlled A/B tests, and communicate what the results do and don't support

 * 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
