iOS Engineer - Digital Identity

About the opportunity

The Digital Identity team at N26 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.

We work at the intersection of security, product quality, and mobile engineering, and the i OS platform is a critical surface for everything we build.

This is a Hybrid role from Barcelona or Vienna.

In this role, you will

• Build and maintain i OS 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 i OS codebase within the Digital Identity domain, working closely with the existing i OS 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 i OS 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 i OS identity layer and tackle complex problems around security, performance, and stability.
• Work with Product and stakeholders to shape the roadmap for the i OS experience within the Digital Identity domain.

What you need to be successful

Background & Skills

• Demonstrated knowledge and deep understanding of the i OS platform and Swift.
• Experience with i OS security frameworks — biometric APIs (Local Authentication), Keychain, or equivalent.
• The ability to showcase your experience with a variety of i OS 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 Test Rail for issue tracking and test case management.
• Full professional proficiency in English.

Traits

• Strong sense of ownership — in a focused team, your work ships directly to customers.
• A systematic problem-solving approach, especially under security and reliability constraints.
• Proactiveness, collaboration, and an eagerness to learn — you'll be working closely with your i OS peer and contributing to a broader mobile engineering community.
• Comfort working autonomously while staying well-connected across platform and backend disciplines.

What's in it for you

• Accelerate your career growth by joining one of Europe's most talked-about disruptors.
• Employee benefits including a competitive personal development budget, work-from-home budget, and discounts for fitness, wellness, language apps, and public transportation.
• A free Premium subscription on your personal N26 bank account, plus subscriptions for friends and family.
• Vacation: An additional day of annual leave for each year of service.
• Autonomy: A high degree of autonomy and access to cutting-edge technologies.
• Relocation: A relocation package with visa support for those who need it.
