Remote (Canada) /
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 a full-time engineer to work on the Expo platform.


Working on the Expo platform means you'll write code in Kotlin, Swift, Java, Objective-C, Objective-C++/C++, and TypeScript that targets iOS, Android, and the web. You'll design the workflow and tools for developing universal apps, including specifications for the way Expo developers write modules for their apps, and contribute to the Expo ecosystem. You'll design APIs that elegantly provide common functionality in a way that feels fully native across the all the Expo target platforms. You'll work on tests and test infrastructure to ensure and improve the robustness and quality of the entire surface area of the platform. 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.
