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.
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
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 the design and delivery of significant components of a service scaling from early customers to broad AWS adoption
• Contribute to technical discussions with partner teams - bring data, document tradeoffs, and help the team land on a decision
• Recognize when a one-off solution is the right call versus when a pattern is emerging that deserves a real abstraction, and raise it with the team
• Raise the bar through thorough code reviews and by helping onboard newer engineers to the codebase and team practices
• Contribute to operational excellence: add monitoring and alarming for the features you build, follow through on production readiness, and take 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 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.
