iOS Engineer - Digital Identity

The Digital Identity team owns the authentication and login experience — the moment every customer interacts with our product. Our mission is to make secure access seamless: biometric login, session management, device trust, and the underlying SDK infrastructure that makes all of it reliable at scale.

What you'll do

• Build and maintain iOS authentication flows — including biometric login (Face ID/Touch ID), session stability, and device management — used by millions of N26 customers.
• Take co-ownership of the iOS codebase within the Digital Identity domain, working closely with the existing iOS engineer to grow shared coverage and resilience.
• Integrate and maintain third-party mobile SDKs (e.g. biometric authentication, security tooling) and own the upgrade and reliability cycle.
• Collaborate with Android and Backend engineers on cross-platform identity features, contributing to API design and shared testing infrastructure.
• Drive iOS regression testing quality — including Testrail suite maintenance and automated test coverage — as a first-class engineering concern.
• Use your platform knowledge to make architectural decisions for the iOS identity layer and tackle complex problems around security, performance, and stability.

What you'll need

• Demonstrated knowledge and deep understanding of the iOS platform and Swift.
• Experience with iOS security frameworks — biometric APIs (LocalAuthentication), Keychain, or equivalent.
• The ability to showcase your experience with a variety of iOS frameworks, including networking, UI, and testing.
• Experience working in an Agile development environment, ideally on authentication, identity, or security-adjacent features.
• An excellent debugger with strong analytical skills — session and device-layer bugs require patience and rigour.
• Proficiency with tools like Jira and TestRail for issue tracking and test case management.
• Full professional proficiency in English.

What they offer

• Competitive personal development budget, work-from-home budget, and discounts for fitness, wellness, language apps, and public transportation.
• Free Premium subscription on your personal N26 bank account, plus subscriptions for friends and family.
• An additional day of annual leave for each year of service.
• High degree of autonomy and access to cutting-edge technologies.
• Relocation package with visa support for those who need it.
