About the role

AWS Fintech is seeking a results-oriented, innovative Senior Software Development Engineer to help create the next generation of distributed, scalable financial systems. You will work on real-world problems at a global scale, own systems end-to-end, and influence technology that impacts customers worldwide. This role involves designing flexible, scalable solutions and tackling complex challenges in large-scale computing using data structures, algorithms, and object-oriented programming.

Responsibilities

• Drive technical vision and architecture for a cohesive finance platform, unifying multiple offerings into a seamless builder experience.
• Design and implement critical-path systems; own the architecture from whiteboard to production, balancing 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, such as 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 by partnering with Principal Engineers and senior leaders.
• Mentor engineers, raise the hiring bar, and cultivate a culture of engineering excellence.
• Research, prototype, and publish design documents, POCs, and recommendations that influence technical and business leaders across AWS Fintech.
• Identify hotspots and eliminate duplicate work across teams by thinking in platforms and building with empathy for engineers who consume your systems.

A day in the life

• Collaborate with Product Managers, Principal Engineers, and partner teams to refine requirements and align on technical direction.
• Prototype and evaluate new technologies, frameworks, or architectural patterns to solve emerging challenges.
• Engage in operational reviews, on-call rotations, and incident response to ensure systems meet AWS Finance’s reliability standards.
• Mentor team members through pairing, design discussions, and code reviews.
• Author and iterate on design documents, technical specs, and architectural decision records.
• Participate in sprint planning and backlog refinement, prioritizing technical debt, feature work, and operational improvements.
