Optic

Making APIs Developer-friendly

YC-S18B2B -> Engineering, Product and DesignEarly

What Optic does

We help developers collaborate at scale and build better APIs. Optic’s open source tools makes it easy for developers to document API changes, review each other’s API changes during code review, and catch breaking changes before they reach production. **tl;dr** It’s version control but for behavior not code. We are taking the really successful ideas from Git / Code Review / CI and applying them to API descriptions and (future) other non-code artifacts. Engineers at [Snyk](https://snyk.io/) use Optic daily to make the new Snyk API great.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
