Software Engineer II - Mobile (Native Foundations)

Job DescriptionJob Description

StubHub is on a mission to redefine the live event experience on a global scale. Whether someone is looking to attend their first event or their hundredth, we're here to delight them all the way from the moment they start looking for a ticket until they step through the gate. The same goes for our sellers. From fans selling a single ticket to the promoters of a worldwide stadium tour, we want StubHub to be the safest, most convenient way to offer a ticket to the millions of fans who browse our platform around the world.

StubHub is seeking a Software Engineer II (React Native) to join our Mobile Foundations team within Consumer App Foundations (CAF).

This team builds and evolves the core React Native platform that powers StubHub's consumer applications. Rather than focusing on feature delivery, Mobile Foundations engineers invest in shared architecture, cross-platform infrastructure, performance, and developer tooling that enable product teams to move quickly while maintaining exceptional quality.

As a React Native-focused engineer on this team, you will work primarily within our cross-platform stack, while collaborating with native iOS and Android layers when needed. You'll contribute to reusable systems and platform capabilities that support millions of users globally and ensure our mobile experience remains performant, scalable, and resilient.

This role is ideal for engineers who enjoy solving foundational problems, improving developer velocity, and owning systems that other engineers depend on every day.

• Experience building internal developer tooling or shared component libraries
• Experience improving mobile CI/CD pipelines and build systems
• Experience with feature flagging, experimentation frameworks, or release infrastructure
