Expo Services & Infrastructure Engineer

Remote (US) /
Engineering /
Full Time
Expo lets developers write React and JavaScript to create apps that work natively across the web, Android, and iOS. We're hiring full-time engineers to work on Expo Application Services (EAS) and its underlying infrastructure.


Working on the Expo services means you'll write code in TypeScript using technologies like React, Next.js, GraphQL, and Node. You'll think through the needs of the developers using Expo, and build elegant, reliable, sensible services that make their live and jobs easier. You'll make choices about what services we build and how they work so you'll need to have a good understanding of app developers, the Expo ecosystem, metrics, reliable systems, and developer products. You'll talk with developers about what is working for them and what isn't, and what they need and don't have yet that we could provide for them. You'll provide direction to and work with open source contributors from the Expo community.
