Front-End Engineer, Kiro

AI is not just changing what software can do; it is fundamentally changing how software is built. We are building the next generation of developer tooling: an AI-native tool that redefines the software engineering workflow from the ground up. Our product sits at the center of a developer’s day, and we are obsessed with making that experience fast, delightful, and powerful.

We are looking for engineers who are passionate about building exceptional user-facing client software. If you care deeply about UI responsiveness, interaction design, and the quality of tools engineers use to build software, this team is for you.

You will work alongside exceptional senior engineering talent solving hard problems at the frontier of AI and developer tooling. You’ll have opportunities to work with and learn from best-in-industry senior engineering talent. In addition to the technical challenges provided by the innovative use cases that we are working on, you will also learn how to build a product that meets AWS’s high bar for availability, scalability, and security.

You’ll have a direct line to our customers’ experience and a direct means of improving it. On a daily basis, you’ll work with teammates to review each other’s code, mentor and be mentored. You’ll have an opportunity to lead from day one, from leading projects, to driving technical processes, to teaching and learning from your teammates. You will have real ownership, from setting technical direction to shipping features that developers notice and love.

Key job responsibilities Own the end-to-end delivery of high-impact, user-facing features built with TypeScript and React, from writing the technical spec to shipping to customers

Drive technical direction for client-side architecture and establish patterns that raise the bar for quality across the team

Work closely with designers and product managers to ensure every feature meets a high bar for developer UX and interaction quality

Build and use AI agents to accelerate your own development workflow

Exercise high judgment about when to guide, override, or take control from AI agents - knowing when to trust automation and when the situation demands your direct involvement

Mentor and guide less tenured engineers, helping them navigate technical challenges, grow their skills, and advance their careers

Work with Product and Design to deeply understand customer workflows and build backward from their needs, maintaining Amazon’s commitment to starting from the customer

A day in the life Use AI agents to write code and move fast, and direct code review agents to help the team catch issues before they ship

Conduct design and UX reviews with your PM and designer to ensure every feature meets a high bar for developer experience

Take full ownership of a feature set actively used by customers, deliver high-impact features end to end, from the initial spec to the moment they ship, and take pride in building software that genuinely delights the developers who use it every day.

Participate in the team’s Weekly Operations Review and understand the key metrics that drive our product

Work with your manager to understand how to grow your career at AWS and how to build a career growth plan

Become an active participant in all stages of our software development cycle, including roadmap planning and product review meetings

Work with other engineers to improve our operational effectiveness by designing new systems and making our current ones more effective

Help onboard new engineers and guide them in their first weeks at AWS

Hold a high bar for user experience in every feature you ship: obsess over every interaction, every millisecond of latency, and choose the path that serves users best even when it is harder to build

Continuously measure, monitor, and improve client-side performance across all supported operating systems

About the team We are a team of engineers who believe the way software is built is about to change permanently, and we are the ones defining that change. We are building an AI-native developer environment that sits at the intersection of cutting-edge AI and the craft of software engineering. Our team is obsessed with the developer experience: we care about performance, interaction design, and the small details that make a tool feel fast and effortless. We dogfood our own product every day, which means every improvement we ship makes us better engineers too. If you want to build the tools that shape how the next generation of software is written, this is the team for you.
