iOS Engineer, Identity

Details

Stripe Identity enables businesses to digitally verify users through identity documents and other signals for fraud prevention, regulatory, and trust and safety use cases. The Identity Product Experience team owns Stripe Identity’s mobile SDKs for iOS, Android, and React Native, helping businesses embed secure, high-quality identity-verification experiences into their mobile applications.

The team’s 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.

Responsibilities

• Design, build, and maintain Stripe Identity’s mobile SDKs and verification experiences across iOS, Android, and React Native.
• Create intuitive, polished experiences for 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.
• Improve SDK performance, reliability, observability, testing, release processes, and backward compatibility.
• Make architectural decisions that balance user experience, developer experience, security, privacy, and long-term maintainability.
• Partner 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 feedback into product and platform improvements.
• Help establish and evolve mobile-engineering practices across Identity and Stripe.
• Operate and maintain the systems and SDKs owned by the team, including diagnosing production issues and improving them based on what is learned.
