About Clerk
Clerk is on a mission to solve user management once and for all. We are a globally distributed team dedicated to providing best-in-class developer experience, with obsessive attention to every detail. Today, we provide developers with full-stack React components and hooks like , , , useUser, and useOrganization. These APIs allow developers to build hard-to-get-right user and organization management flows. We believe that a component is worth a thousand APIs.
About the Role
We're looking for a passionate Software Engineer to take ownership of our Expo and Flutter SDKs. Our Expo SDK is already one of our most popular offerings, trusted by thousands of developers building React Native applications. Our Flutter SDK recently entered beta and is already being used in production by many customers.
As the lead engineer for these mobile frameworks, you'll be responsible for maintaining, supporting, and continuously improving these critical SDKs that enable developers to add authentication and user management to their mobile applications with just a few lines of code.
What you’ll do
SDK Development & Maintenance
Take full ownership of Clerk's Expo and Flutter SDKs, from architecture to implementation
Design and implement new Clerk features that make authentication even better for mobile developers
Maintain high code quality, security standards, and performance across both SDKs
Write comprehensive documentation, guides, and code examples that developers actually want to read
Developer Experience
Collaborate with our marketing & support teams to understand pain points and feature requests
Create sample applications and integration guides that showcase best practices
Respond to community questions and provide technical support for SDK-related issues
Contribute to our open-source ecosystem and engage with the developer community
Cross-Platform Excellence
Ensure seamless functionality across iOS, Android, and web platforms for both Flutter and Expo
Work closely with our native iOS and Android developers to maintain consistency across all mobile SDKs
Stay current with React Native, Expo, and Flutter ecosystem changes and updates
Optimize for performance, security, and developer ergonomics
Strategic Development
Define the technical roadmap for mobile SDK development
Evaluate and potentially lead development for additional mobile frameworks based on customer demand
Collaborate with Product and Engineering teams to prioritize features and improvements
Influence Clerk's overall mobile strategy based on your deep ecosystem knowledge
Who you are
Required Experience
3+ years of software engineering experience, with significant mobile development focus
Strong experience with JavaScript/TypeScript (React Native/Expo), ideally direct experience working with Expo
Experience building and maintaining SDKs, libraries, or developer tools
Understanding of authentication flows, security best practices, and mobile-specific considerations
Knowledge of authentication protocols (OAuth, SAML, JWT)
Experience with API integration, state management, and mobile app architecture patterns
Experience with Git, package managers (pub.dev, npm), and collaborative development workflows
Nice to Have
