Are you ready to build the future of financial technology at Amazon scale? Are you excited by greenfield initiatives that let you architect and ship brand-new systems from the ground up? Do you want to push the boundaries of what's possible with Generative AI to re-imagine the payments experience for our partners worldwide? If the idea of owning mission-critical services that move billions of dollars, support Amazon's finance functions, and must operate with high uptime gets your pulse racing — Amazon Finance Technology (FinTech) Payments is where you belong.

Who We Are

FinTech Payments handles the processing and disbursement of vendor payments across Amazon's global marketplaces, leveraging cutting-edge technologies and a modernized payments architecture. We build and operate highly scalable, distributed systems on AWS that rival the complexity and scope of the world's leading payments fintech companies — processing financial transactions worth billions of USD annually and growing.

We partner with financial institutions and Amazon business teams (Retail, Corp, Transportation, Digital) worldwide to deliver best-in-class payment capabilities. We delight our vendors by paying them when they want and how they want — on time, every time.

What Makes This Role Special

- Greenfield Development: We are building entirely new, industry-standard payments products from scratch — designing and launching services from the ground up to process and disburse on-time payments at massive scale. This is your chance to define the architecture, set the technical direction, and leave your fingerprint on systems that will serve Amazon for years to come.

- Highly Scalable Systems: Our services are at the heart of Amazon's financial operations. You'll own systems that must scale seamlessly with Amazon's ever-growing payment volumes, maintain high availability, and meet the highest bar for reliability, security, and performance.

- Full-Stack Innovation with Micro-Front End Architecture: We're building modern, cohesive web applications using a federated micro-front end architecture — enabling finance and business customers to operate their critical functions through intuitive, modular, and independently deployable UIs. You'll work across the full stack, from scalable backend services to polished front-end experiences.

- GenAI-Powered Solutions: We are heavily investing in Generative AI to deliver novel, AI-driven solutions for our finance customers. From intelligent transaction insights and anomaly detection to AI-assisted reporting and smart payment recommendations — you'll leverage GenAI to transform how end customers interact with financial data and make decisions. This isn't incremental improvement; it's reimagining the payments experience through AI.

What We're Looking For

We want individuals who are passionate about creating new products, features, and services from scratch — people who thrive in ambiguity and move at the pace of a company where development cycles are measured in weeks, not years. You should be excited about:

- Moving real money and paying people on time at global scale
- Innovating payments and CX using GenAI.
- Ensuring Amazon's financials are reported timely and accurately
- Building systems that handle exponential growth with zero downtime
- Support Federated User Interface (UI) framework for multiple partner teams serving their end customers.

- Crafting seamless, unified user experiences for finance customers

- Collaborating with world-class engineering talent across Amazon and AWS

If you're an engineer who wants to build big, build new, and build smart — combining the thrill of greenfield development with the impact of AI-powered innovation at Amazon scale — we have the opportunity for you.
