iOS Engineer, Identity Product

Stripe•Seattle, WA

About The Position

The iOS Engineer will join Stripe Identity’s Product Experience team, which builds mobile SDKs for iOS, Android, and React Native. These SDKs let businesses embed secure, high-quality identity-verification experiences in their mobile applications. The work spans mobile user experience, reusable SDK architecture, camera and document capture, developer experience, security, accessibility, reliability, and integration with Stripe backend systems. The role involves designing, building, and maintaining mobile SDKs and verification experiences; creating polished identity-document and selfie-capture flows; and developing reliable, extensible APIs and reusable components for developers. Engineers work across mobile clients, supporting APIs, and services to deliver features end to end, while improving performance, reliability, observability, testing, releases, and backward compatibility. They make architectural decisions that balance user and developer experience, security, privacy, and maintainability; collaborate across disciplines and with Stripe users; help improve mobile-engineering practices; and operate and maintain the systems and SDKs they own.

Requirements

At least 3 years of professional software-development experience, including meaningful experience building and shipping mobile applications or SDKs.
Experience developing for at least one major mobile platform using technologies such as Swift or Objective-C for iOS.
Strong software-design fundamentals and experience creating maintainable APIs, components, or frameworks.
Experience delivering mobile functionality beyond an isolated UI layer, such as integrating with APIs and services, handling local state, or using device capabilities.
Experience testing, debugging, monitoring, and improving mobile software in production.
Ability to collaborate effectively with engineering, product, design, and other technical and non-technical partners.
Demonstrated commitment to building high-quality user and developer experiences.

Nice To Haves

Experience building mobile SDKs, shared libraries, or developer-facing APIs used outside the immediate team.
Experience with both iOS and Android, or cross-platform technologies such as React Native or Kotlin Multiplatform.
Experience with camera, image-processing, document-capture, biometrics, or other device-integrated mobile experiences.
Experience designing mobile software that handles sensitive data and applies security and privacy principles by default.
Familiarity with accessibility, internationalization, mobile performance, and unreliable network conditions.
Experience with mobile CI, automated testing, release automation, observability, or developer-productivity tooling.
Experience contributing to backend APIs or services that support mobile products.
Ability to simplify complex requirements and favor durable, scalable solutions.
Comfort reasoning clearly and moving with urgency in a fast-paced, ambiguous environment.
Familiarity with Stripe’s products, ideally through integrating Stripe APIs or SDKs into another application.
