The problems here are genuinely new. How do you proactively surface useful context across thousands of conversations? How do you package that into a product experience that feels magic, not noisy? These are greenfield problems–no established playbook, lots of room to define the right approach.
Day to day, you'll:
Ship end-to-end across our web (React, Next.js), desktop (Electron, Swift), and mobile apps (React Native)–from database models to API endpoints to UI
Design and architect new systems while raising the bar for code quality
Drive product and technical decisions, not just implement them
Work on hard foundations: AI-powered outcomes, search, transcription, on-device recording, performance, automations
Experiment with the latest AI models and techniques–we ship AI features constantly and need engineers who stay curious about what's newly possible
Build processes and tools that make the whole team more productive over time
You've built and shipped software at a high level before. You have strong product sense–you notice details, you have opinions about how things should work, and you can mentor other engineers through code review and technical guidance.
You're drawn to work that compounds. On the team side: you'd rather spend an extra half-hour building something reusable than copy-paste your way to done. You think about how decisions today affect velocity next month. On the product side: our foundations stack on each other–better transcription means better AI outcomes, which means better search and automations. And when the product gets noticeably better, people tell their friends–that's how we grow.

Circleback is building the source of truth for everything said at a company–starting with best-in-class AI meeting notes, action items, and search.
Every meeting will be AI-enabled. But meeting notes are just the beginning. We're building toward something larger: a platform that captures, organizes, and actions on the context from all conversations across a company–meetings, calls, emails–so teams can actually use what they know.
We're a small team backed by Y Combinator. Profitable, growing virally, and thousands of paying customers including PostHog, Browserbase, Gumloop, and more.
Why joinWe ship fast with a high bar for quality
Small team, large problem–the product category we're building didn't exist until recently
Profitable and growing virally through word of mouth
Software that people actually love and use daily
If you care about craft and want to build something ambitious with a small team that moves quickly, we'd like to hear from you.
