Engineering at Privy is not just about writing world-class code. We create software that turns complex technical systems into delightful developer tools. We assemble tried-and-true primitives into intuitive, responsive APIs and beautiful interfaces. We believe in open-source work and transparency with our teammates and users. We encourage each other to think big, run experiments and follow our curiosity so we can build better tooling that lets developers shine and empower their users.

What You’ll Do

As an SDK Engineer at Privy, you are the architect of the primary integration surface. You will not only lead the evolution and maintenance of our React and React Native SDKs, but you will help support other Privy SDKs. Your work will help shape the narrative of customer satisfaction, so maintaining a world-class developer experience is a top priority. Your mission is to ensure that integration is quick, frictionless, and intuitive.

You will be responsible for ensuring that whether a developer chooses our React, iOS, Android, or server-side offerings, they encounter the same consistent interfaces and quality standards across the board. Your work will help ensure Privy is defined as the golden standard of SDKs.

• Lead the React & React Native Ecosystem: You will be the primary owner for our React-based SDKs, ensuring we maintain a first-class experience for React Native mobile developers.
• Maintain Cross-Platform Parity: While you own the React stack, you will contribute to and oversee the consistency of our iOS, Android, and server-side SDKs. You'll ensure a "Privy developer" feels at home regardless of the language they are using.
• Drive Technical Excellence: Build the CI/CD pipelines and automation logic that allow our team to efficiently maintain 10+ high-quality SDKs without increasing the burden on the rest of the engineering org.
• Lead API & Schema Design: Partner with backend engineers to advise on upstream OpenAPI design decisions, ensuring that API changes translate into consistent, intuitive, and native-feeling developer experiences downstream.
• Customer support: Serve as a specialized technical point of contact for P0/P1 customers during integration. Customer satisfaction is non-negotiable.
• Establish Best Practices & Tooling: Develop the internal tooling and "SDK Runbooks" to empower and educate the rest of the engineering team, allowing them to ship API changes with confidence while maintaining our SDK quality.
• End-to-End Craftsmanship: Write technical docs, recipes, and code samples with the same care as our code, ensuring every feature is truly complete and the developer journey is as short and frictionless as possible.

Who you are
