Senior Frontend Engineer, AWS Applied AI Solutions

AWS Applied AI Solutions (AAIS) is building toward a future where every business innovates with Amazon AI teammates. To get there we build AI solutions that improve human capabilities and transform entire business functions. We create end-to-end products that surprise and delight out-of-the-box making complex things easy and hard things possible with no cloud experience required. We start with customers who embrace the future and build bridges to meet the rest where they are. We pursue ambitious opportunities with conviction and we are looking for builders who share that mindset.

Were building Chorus a real-time document workspace where AI agents are actual collaborators: an agent gets a cursor in the doc edits the same CRDT and shows up in presence right next to you. We wrote it from scratch in Rust and TypeScript; we sync in under 50ms with hundreds of simultaneous editors on a single document and it costs roughly a dollar per builder per year to run. Its an exciting combination of greenfield work with a massive user base that provides immediate feedback when something doesnt work.

Requirements

You proactively seek out problems propose solutions and own delivery
You find ways to deliver code with agents at high speed without sacrificing the quality of the code or the software.
Experience in building distributed and high-concurrency systems
Were a small team with an unusually direct line from idea to thousands of builders using it. If you want to be one of maybe a dozen people in the world shipping production CRDT infrastructure that treats AI as a peer this is the job.

Key job responsibilities
Own the front end of a real-time collaborative editing product end to end: its architecture performance and reliability as it grows from early customers to broad AWS adoption
Take a front end that grew faster than its foundations and make it one the team can move quickly and safely in. Find the worst pain points set a direction and drive the cleanup to completion
Design and deliver major features on a modern editor stack (React TipTap/ProseMirror Yjs CRDTs Rust compiled to WASM) balancing short-term delivery with long-term health
Know when a one-off fix is the right call and when a repeated pattern needs a shared component hook or abstraction. Raise it with the team and build it
Lead technical discussions with backend and partner teams on API contracts real-time sync behavior and UX tradeoffs. Bring data write down the options and help the team reach a decision
Raise the front-end bar through thorough code reviews and clear conventions for state management testing and component design and by onboarding newer engineers into the codebase
Make the front end observable and production-ready: client-side error and performance monitoring alarms on what you ship solid test coverage and real ownership during on-call


A day in the life
Your mornings are usually free for focus work -- architecture deep dives and hard problems. Around 11 youll have standup then grab lunch with the team (if you like) before the afternoon opens up for design reviews CR feedback or unblocking an engineer. Some days youre deep in code; others youre on a call with a customer team working through how their system integrates with yours. Youre the person who knows the system most deeply -- and you work to ensure youre never the bottleneck. The problems are hard and the stakes are high -- but we believe we can move fast do exceptional work and have a full life outside of it.
