About Nebius: Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure. Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI. Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D. In a rapidly evolving world, trust in AI depends on AI agents being grounded in fresh, verified real-world data. Search is the foundation that makes this possible. In this role, you will define what quality means for a search system built for AI agents from day one. In this position, your responsibility will be to * Own search-related quality metrics end-to-end: from definition and computation to evolution and transition to next-generation metrics. * Design and reason about analytics architecture across the full stack: runtime behaviour → data pipelines → metrics → dashboards. * Develop and maintain analytics pipelines and tooling using Python. * Translate product, user, and technical requirements into meaningful, actionable metrics. * Challenge existing assumptions about quality and push for better, more reliable measurement. * Work closely with product managers, engineers, and stakeholders to align analytics with system behavior and business goals. * Debug metric anomalies, investigate quality regressions, and propose data-driven improvements. We expect you to have * Senior-level experience solving search or search-adjacent analytical problems. * Strong exposure to quality metrics in at least one of the following areas: * search relevance (web, geo, product, offers), * ranking and freshness, * ads quality or feed ranking. * Ability to think end-to-end across users, products, and technology, not just individual metrics. * Solid foundation in mathematical statistics. * Strong Python skills and a hands-on engineering mindset. * Experience operating in ambiguous environments and driving solutions independently. * Clear analytical judgment: understanding why a metric exists, how it evolves, and when it should be retired. * Strong communication skills and the ability to align product, engineering, and client perspectives. Benefits & Perks: * Competitive compensation * Career growth and learning opportunities * Flexibility and ownership * Collaborative and innovative culture * Opportunity to work on impactful AI projects * International environment and talented teams What's it like to work at Nebius: Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI Equal Opportunity Statement: Nebius is an equal opportunity employer.
