Senior Software Engineer, AWS Applied AI Solutions

As part of the AWS Applied AI Solutions organization, we have a vision to provide business applications, leveraging Amazon’s unique experience and expertise, that are used by millions of companies worldwide to manage day-to-day operations. We will accomplish this by accelerating our customers’ businesses through delivery of intuitive and differentiated technology solutions that solve enduring business challenges. We blend vision with curiosity and Amazon’s real-world experience to build opinionated, turnkey solutions. Where customers prefer to buy over build, we become their trusted partner with solutions that are no-brainers to buy and easy to use.

We're 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. It's an exciting combination of greenfield work with a massive user base that provides immediate feedback when something doesn't work.

We're 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 end-to-end technical architecture for a service that is scaling from early customers to AWS-wide adoption

• Work directly with internal and eventually external customers to understand integration needs, set expectations, and turn real-time feedback into service direction

• Drive technical consensus across partner teams with competing priorities and constraints

• Make judgment calls on when to solve a problem scrappily for one customer and when to build the abstraction that serves many

• Mentor and develop junior and mid-level engineers through code reviews and design reviews

• Drive operational excellence: define monitoring and alarming standards, ensure production readiness for new features, and build a culture where the team can sustain what it ships

• You own a problem space end to end, identify the most salient problems now and deliver solutions quickly without sacrificing long-term scalability

• Inventive usage of LLMs in software development. You find ways to deliver code with agents at high speed, but without sacrificing the quality of the code or the software.

• Deep experience in Rust or systems-level TypeScript, or the track record to show you'll get there fast. We care more about how you think about correctness under concurrency than which language you learned it in.

A day in the life

Your mornings are usually free for focus work - architecture, deep dives, and hard problems. Around 11 you'll 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 you're deep in code; others you're on a call with a customer team working through how their system integrates with yours. You're the person who knows the system most deeply - and you work to ensure you're 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.

We're a small team building two greenfield projects within Agentic WorkSpaces. We're moving fast enough that our team name is still taking shape — but our engineering culture is well established.
