AWS Fintech's data platform powers financial reporting for all of AWS — every dollar, every data point. As a Sr. Software Development Engineer (Sr. SDE) on the Data Platform team (DataFI), you will shape how Amazon understands its cloud business by driving the technical vision, architecture, and implementation of platform capabilities that thousands of engineers and finance professionals depend on daily. You will lead system design, implement critical-path code, define and raise engineering standards, and drive operational readiness for a suite of products used across AWS Fintech, AWS, and Amazon. This role demands end-to-end expertise across the data stack, versatility in complex and evolving technologies, and excellent judgment to balance large-scale architectural decisions with enabling fast experimentation and time-to-market. We are looking for a seasoned builder who thrives at the intersection of scale, complexity, and craft — someone who decomposes ambiguous problems into actionable technical roadmaps and then builds them. Key job responsibilities - Drive technical vision and architecture for a cohesive data platform, unifying multiple offerings into a seamless builder experience. - Design and implement critical-path systems — own the architecture from whiteboard to production, making decisions that balance scalability with speed-to-market. - Define and raise engineering standards across the team — code quality, operational readiness, testing patterns, and documentation. - Solve hard technical problems: sub-second OLAP queries over petabyte-scale financial datasets, building trust through lineage spanning hundreds of pipelines, and designing AI-driven root-cause analysis for data quality at enterprise scale. - Influence data strategy and investment decisions, partnering with Principal Engineers and senior leaders to shape where we invest next. - Mentor engineers and raise the hiring bar — grow the people around you and cultivate a culture of engineering excell
