Senior Fullstack Engineer

Circleback•San Francisco, CA

About The Position

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 that moves fast. You'll ship real features to thousands of paying customers every week, not sit in planning meetings. You'll take on a problem, figure out the right approach, build it across the full stack, and ship it. That requires good judgment. It means understanding how a feature connects to everything else, both technically and from a product standpoint. Our foundations stack on each other: better transcription means better AI outcomes, which means better search and automations. An engineer who builds in isolation here will build the wrong thing. You'll ship across web (React, Next.js), desktop (Electron, Swift), mobile (React Native), and backend. You'll work on AI-powered outcomes, search, transcription, on-device recording, performance, and automations. You'll experiment with new AI models and techniques. And you'll raise the bar for the team through code review and building reusable tools.

Drawn to work that compounds.
Curious how great products work.
