iOS Engineer, Identity

Who we are About Stripe Stripe is a financial infrastructure platform for businesses. Millions of companies from the world’s largest enterprises to the most ambitious startups use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone’s reach while doing the most important work of your career. About the team Before Stripe, every growing internet platform needed a payments team. Today, every growing internet platform needs a way to establish trust in its users. Identity verification is a core piece of economic infrastructure for online businesses. Stripe Identity enables businesses to digitally verify their users through identity documents and other signals for fraud prevention, regulatory, and trust and safety use cases. We are building the future of identity verification and trust in the digital economy. The Identity Product Experience team owns Stripe Identity’s mobile SDKs for iOS, Android, and React Native. These SDKs enable businesses to embed secure, high-quality identity-verification experiences directly in their mobile applications. Our work spans mobile user experience, reusable SDK architecture, camera and document-capture experiences, developer experience, security, accessibility, reliability, and integration with Stripe’s backend systems. Why Stripe Identity? Build mobile experiences that help establish trust between businesses and their users. Solve challenging product and technical problems involving mobile platforms, sensitive data, fraud prevention, and global scale. Create SDKs used by developers across industries, including fintech, marketplaces, and online platforms. Help shape the future of digital identity and make verification easier, safer, and more accessible. Our vision is to build the world’s most trusted store of verified identities, enabling frictionless identity verification across Stripe and beyond. We’re looking for engineers who care deeply about mobile craft and the entire user journey. You should enjoy translating complex technical and regulatory requirements into simple, polished experiences; working through ambiguity; and learning new technologies and systems. Join us to build mobile identity-verification experiences that businesses can integrate easily and that their users can trust. What you’ll do Responsibilities As an iOS engineer on the Identity team, you will: Design, build, and maintain Stripe Identity’s mobile SDKs and verification experiences across iOS, Android, and React Native. Create intuitive, polished experiences for complex flows such as identity-document and selfie capture, while accounting for accessibility, device capabilities, and varied real-world conditions. Build reliable and extensible SDK APIs and reusable components that make it easy for developers to integrate Stripe Identity into their applications. Work across mobile clients, supporting APIs, and services to deliver features end to end rather than treating the mobile application as an isolated layer. Improve SDK performance, reliability, observability, testing, release processes, and backward compatibility. Make thoughtful architectural decisions that balance user experience, developer experience, security, privacy, and long-term maintainability. Partner closely with product managers, designers, machine-learning engineers, backend engineers, user researchers, and other mobile teams. Work with Stripe users and field teams to understand integration challenges and turn their feedback into product and platform improvements. Help establish and evolve mobile-engineering practices across Identity and Stripe. Operate and maintain the systems and SDKs the team owns, including diagnosing production issues and improving them based on what we learn.
