Job description

Expo is agentic mobile infrastructure for building, shipping, and running native apps for iOS, Android, and the web. Millions of developers and AI agents use Expo's open-source framework and cloud services to go from idea to production, with tools to build, submit to the app stores, ship over-the-air updates, and monitor performance and crashes at scale. Founded in 2015, Expo is on a mission to make great software development accessible to everyone.

Behind EAS are web services and infrastructure that serve both developers and their end users. Developers rely on EAS to build their own apps and making our backend infrastructure for building apps, running CI/CD workflows, serving app updates, and web hosting reliable is one of the ways we build developer trust. We're looking for engineers early in their career to come work with us on EAS's infrastructure and help us provide developers with new services, scale to their workloads, and continuously improve performance and efficiency.

What you’ll do

• Join EAS's infrastructure team as an early-career engineer, working alongside a senior engineer.
• Learn to design, build, and operate the backend infrastructure behind our developer-facing services, on our Linux fleet and cloud foundation.
• Build internal improvements that make our services easier to manage, faster, and cheaper to run, and make Expo a better place to work.
• Write software that runs correctly and efficiently, and own its uptime and performance.
• Own the code you write: add tests and monitoring, and join your team's on-call rotation.

What you’ll bring

• You're curious about Linux, containers, and writing small services, and you have some experience with each.
• You've built something real, end to end, with users or real load on it.
• You're comfortable with virtual machines and containers.
• You have cloud experience. We use Google Cloud, but deep experience with AWS, Azure, or a home lab carries over well.
• You have the knowledge taught in courses on operating systems, networks, databases, and distributed systems, whether you learned it in school or on your own.
• You've gone deep on at least one low-level area: the operating system, the network, a cloud, or the deploy path.
• You're comfortable writing code and want to write a lot more of it.
• Bonus: systems-level knowledge of macOS or networking.
• You make sound decisions on your own and bring new, effective ideas to improve how app software is built and distributed.
• You write services that stay healthy long after you've moved on to your next project.
• You respond quickly to teammates so Expo keeps making fast, steady progress.
• You get yourself unstuck and help others get unstuck too.
• You know why well-designed tools and APIs matter, and you ship well-designed, well-tested features quickly.
• You communicate ideas and code clearly through documentation, GitHub reviews, blog posts, and other writing.
• You understand the problems and goals of Expo's users and think about them every day.
• You use agents for real work every day, and you can explain what you checked before you trusted the result.
• You get better every week. You're curious and focused, and you own what you run.
