Amazon Advertising is one of Amazon's fastest growing and most profitable businesses, responsible for defining and delivering AI-powered solutions that transform how advertisers make strategic decisions. The Advertiser Experience (AX) group owns the end-to-end experience of advertisers on our platform — from first engagement through the full lifecycle of self-service campaign management, analytics, and optimization.

We are at an inflection point. The next generation of advertising tools will be shaped by agentic experiences, AI-assisted workflows, and intelligent interfaces that anticipate advertiser needs before they articulate them. We are building the foundational views and interaction patterns that will define how advertisers interact with our platform for years to come.

We are looking for a Front-End Engineer II to design, build, and optimize scalable, high-performance web applications that blend traditional UI with conversational and autonomous interfaces. You will collaborate with product, design, applied science, and backend teams to deliver intuitive user experiences. You'll work with emerging technologies — large language models, generative UI, adaptive layouts — and figure out how to apply them at Amazon scale with the quality bar our advertisers expect.

Key job responsibilities

• Design, develop, and maintain responsive, high-performance front-end applications using modern frameworks (React, TypeScript)
• Build novel, agent-driven experiences that combine structured UI with AI-powered interactions
• Partner with UX designers, product managers, applied scientists, and backend engineers to translate requirements into polished user interfaces
• Write clean, well-tested, and maintainable code following best practices and coding standards
• Own the delivery of major features end-to-end, from technical design through production launch
• Identify and resolve performance bottlenecks, accessibility issues, and cross-browser compatibility problems
• Contribute to architectural decisions and help define front-end best practices and standards for next-generation advertising views
• Continuously improve development processes, tooling, and CI/CD pipelines

About the team
Advertising at Amazon is growing incredibly fast by providing efficient tools to drive sales for our vendors and sellers.

The Campaign Management team ensures Advertisers can easily use tools to launch their campaigns independently. We are looking for a pioneering and collaborative Front-End Engineer to work in our unique, product-focused “2-pizza team.” You will sit side-by-side with product owners, contributing to the new ideas that will become your projects. You will build applications and that provide the right help in the right place at the right time. If you are a Front-End Development Engineer who is interested in being close to the business problems, wants to broaden your leadership skills, and are passionate about delivering world class user experiences, we would love to talk to you.
