Software Development Manager, AWS Payments & Fraud Prevention

Are you passionate about building highly scalable distributed systems that protect millions of customers? Do you want to work at the intersection of big data, real-time intelligence, and fraud prevention? The AWS Payments & Fraud Prevention team is looking for a talented software development manager to help us stay one step ahead of bad actors. You'll be leading the data ingestion and intelligence team that design and build systems that process millions of events per second, develop machine learning-powered fraud detection processes, and directly contribute to keeping AWS safe. Whether it's architecting a new real-time detection engine, optimizing our graph-based fraud network analysis, or hardening our registration fraud defenses — your work will have immediate, measurable impact at AWS scale. Key job responsibilities * Own and operate a large-scale data ingestion platform processing 18+ billion events per day, ensuring data is ingested, enriched, and transformed in near real-time to power fraud detection and prevention across the organization. * Lead the design, development, and maintenance of real-time intelligence pipelines using Apache Flink for data aggregation, anomaly detection, and usage pattern analysis. * Drive the development of a graph database of millions of nodes and edges to model account relationships and surface fraud signals. * Ensure high availability, reliability, and scalability of all platform services, including data vending APIs operating at 4,500+ TPS, as business demands and the AWS customer base grow. * Own day-to-day team operations, including sprint planning, technical design reviews, operational excellence, and on-call management. * Plan and execute the team's multi-year technical strategy, aligning platform capabilities with evolving business and security needs. * Collaborate closely with Applied Scientists to identify and deliver the data products they need to detect and prevent fraud and account compromise faster. * Serve as a technical leader with hands-on depth, diving deep with SDEs to review architectures, and resolve platform issues. * Ensure platform services meet the needs of all downstream engineering and data science teams across the organization who depend on this team's products.
