Senior Software Engineer

Remote Full-time

We're looking for a software engineer with strong product sense and sharp technical judgment to join us in San Francisco.

What you'll do

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.

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.

Who you are

3-5 years of experience building and shipping software, preferably at startups. You've made real decisions, not just about implementation, but about what the right product and technical approach was.

An eye for detail. Strong opinions about how things should work. The kind of person who thinks about how something fits into the bigger picture, not just whether the code works.

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

AI-native. The way software gets built is changing fast (exciting). Not just keeping up, but at the frontier. Always looking for ways to get better at doing the work, not just doing the work.
