The International Personalization team is part of Walmart's International Tech organization, responsible for building the intelligent systems that make every customer interaction across Walmart's global markets feel uniquely relevant. We own the end-to-end personalization stack — from real-time feature pipelines and ML model serving to recommendation engines, search ranking, and experimentation platforms — powering experiences for hundreds of millions of customers across 19+ countries. Our team operates at the intersection of backend engineering, data science, and product innovation, tackling some of the most challenging problems in large-scale personalized commerce. We are a team-oriented, globally distributed group of engineers and scientists who value technical excellence, data-driven decision-making, and a culture of continuous learning. If you're passionate about building systems that directly shape how customers discover and engage with products at massive scale, this is the team for you.
