We are evolving from a classic Data Science function toward an AI-native team: embedded alongside Product, R&D, GTMand Design, we frame the right problems early, prototype fast, and build trusted, reusable AI systems that help Criteo ship better products, faster, harnessing Product Intelligence.\nThink \"diagnose the messy problem and build the tool that solves it\": our approach combines product judgment, data, and hands-on technical fluency.\nIn this internship, building AI agents and skills is at the center of the role. You will design, prototype and evaluate agents that change how PAX and our Product partners work. Agents you build and validate can graduate into owned, production capabilities for the team.\nWondering how life is in the PAX team? Take a peek at Live my life with the Product Analytics & Data Science team.\nYou will be assigned to one or several projects. The topics we tackle are wide and always evolving. Recent examples of the AI-native, agentic work you could contribute to:\nBuild AI agents & skills for the team - design agents that automate recurring analytical work (e.g. a reporting agent, a Slack assistant, an AI skill), and ship them into our shared skills registry so the whole team benefits.\n\nAgent evaluation & guardrails - help build frameworks that evaluate multi-turn agents (LLM-driven personas talk to a real agent, LLM judges score relevance, coherence, helpfulness, safety and accuracy), so agentic products ship faster and more safely.\n\nProduct intelligence prototypes - build retrieval / embedding-based systems for product understanding (e.g. semantic search over publisher content for supply discovery, brand safety, or audience creation).\n\nLLM-powered diagnostics at scale - use LLMs to detect, sample and route quality issues across complex product pipelines (e.g. tracing where a catalog signal is lost and who should fix it).\n\nMessy, cross-functional product problems - jump into ambiguous product and client challenges (identity, measurement, trading, creative validation) and use fast prototyping and AI tooling to converge on solutions that work in the real world.\n\nOverall, your responsibilities include:\nDesign, build and evaluate AI agents and reusable skills that solve real product and analytical problems\n\nSupport the team in framing product and client problems early with PM, R&D, GTMand Design - then prototype narrow, high-value solutions quickly\n\nBuild evaluators, guardrails and golden-dataset tests so the systems you ship are trustworthy\n\nTurn repetitive manual tasks into trusted agents that scale beyond you\n\nMine large data sets and turn them into understandable and actionable insights\n\nMaster our internal analytic datasets, tooling and AI stack\n\nWho You Are:\nMaster's degree student or higher (Mathematics, Computer Science, Physics, Engineering, Economics, etc.)\n\nAvailable for at least 5 to 6 months from January 2027.\n\nEnd of study or gap year internship\n\nOutstanding analytical skills, creative thinking, and a builder's mindset - you like to prototype, not just analyze\n\nFluency in the core toolkit of Data Science: Python; SQL; manipulating large-scale data sets; building data pipelines; descriptive and predictive modeling; implementing visualizations, dashboards and reports\n\nCuriosity and ideally hands-on experience (through projects, coursework or personal tinkering) with the AI-native toolkit: LLMs and prompting, building agents or skills, retrieval / embeddings, or agent evaluation - or a strong eagerness to learn these fast\n\nExcellent interpersonal and communication skills, pro-active and independent to work with!\n\nPS: Please apply with an English resume\nWe acknowledge that many candidates may not meet every single role requirement listed above.
