Come help us create innovative capabilities for Amazon's Associates, managers, and leaders to support the evolution of People eXperience and Technology (PXT). The Workforce Solutions (WS) team builds and delivers world-class products for Amazon's employees — we believe happy Amazon customers start with happy Amazon employees! We give associates around the globe the flexibility to enrich their job experience. As a member of this team, you are changing people's lives by building the tools that help them advance in their careers. Behind these products sits a genuinely interesting engineering challenge: we build distributed, event-driven microservices on native AWS (Java, DynamoDB, SQS, EventBridge, ECS Fargate, ElastiCache, infrastructure as code with CDK) that serves over one million employees across multiple countries in real time. Our systems must encode country-specific rules and regulations into a single scalable platform, process large volumes of operational data through orchestrated workflow pipelines, and hold a high bar for availability and data correctness — because our outputs directly affect employees' pay and careers. We are also actively modernizing: re-architecting established systems onto a next-generation microservices platform, with safe, validated migrations — so you'll get both greenfield design work and the satisfaction of retiring legacy.
