About us

We are looking for people who want to shape the future with us. As part of SPRIND, an organization that is called the Federal Agency for Breakthrough Innovations but thinks like a start-up. Our goal is to create new breakthrough innovations from Germany. That means products, services and systems that make all of our lives noticeably and sustainably better. To do this, we connect new thinkers from science and business, people with outstanding ideas, special expertise and passion.

In the EUDI Wallet Ecosystem project, which SPRIND is carrying out on behalf of the newly formed Federal Ministry of the Digitalization and State Modernization (BMDS), a concept for a German implementation of the EU eIDAS 2.0 regulation including a digital wallet is being developed and tested. Representatives of organized civil society, business associations and administration as well as experts from science are involved in a public consultation process that accompanies the project. Mid-term this project will be transformed into a to-be-founded government-owned entity that takes over the EUDI Ecosystem for the permanent further development and operation of the platform.

Your role

We’re looking for an experienced Mobile Engineer (m/f/d) iOS to join a small, highly skilled team building a secure, government-grade mobile wallet. You’ll take technical ownership of the iOS codebase and play a key role in shaping our app architecture, ensuring quality, performance, and reliability at scale.

As a senior technical contributor, you’ll work closely with mobile security experts, backend engineers, and product teams to build robust features that meet the highest standards for usability, security, and maintainability.

You’ll focus purely on engineering excellence — no infrastructure or operations work required.

Your Responsibilities

• Design and development of our iOS application using Swift and modern Apple frameworks.
• Define and maintain a scalable, modular app architecture that supports long-term growth.
• Ensure strong integration with backend APIs and collaborate closely with the Mobile Security team.
• Implement and maintain secure data handling, optionally including Secure Enclave integration.
• Drive code quality through rigorous code reviews, unit testing, and continuous integration.
• Mentor other engineers, sharing best practices in iOS development and architecture design.
• Collaborate with product managers and designers to deliver a seamless, user-friendly experience.
• Stay current with iOS trends, Apple platform updates, and new developer tools.

What we’re looking for:

• 7+ years of professional experience in iOS development
• Deep knowledge of Swift, UIKit/SwiftUI and modern iOS architecture patterns (MVC, MVVM, Clean Architecture).
• Experience designing complex mobile systems and leading technical decisions across teams.
• Familiarity with iOS platform security features such as Keychain, Secure Enclave, or biometric authentication is a plus.
• Experience with API design, networking, and offline-first patterns.
• Passion for writing clean, testable, and well-documented code.
• Excellent communication and collaboration skills.
• Fluent in English; German is a plus.

What we offer:

• A chance to shape one of Germany’s most important digital public infrastructures
• A forward-thinking, mission-driven work culture at the intersection of science, administration, and innovation
• Attractive compensation based on the responsibility of the position
• Flexible working hours and remote work options
• Access to conferences, team events and a supportive work culture.
