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) Kotlin to join a small, experienced team building a secure, government-grade mobile wallet. You’ll contribute to the ongoing development of our Android application, implementing new features and ensuring high-quality, reliable, and maintainable code.

You’ll work closely with other Android and iOS engineers, the mobile security team, and backend developers to deliver a seamless, secure, and performant user experience.

This role focuses purely on mobile engineering — infrastructure and operations are handled by a separate vendor.

Your Responsibilities

• Develop and maintain our Android application using Kotlin and modern Android frameworks.
• Collaborate with senior engineers on architectural decisions and feature planning.
• Ensure smooth integration with backend APIs and contribute to secure data handling.
• Write clean, maintainable, and well-tested code under continuous review.
• Participate in code reviews and share feedback with peers.
• Work closely with product managers and designers to implement user-friendly and accessible features.
• Stay up to date with Android development trends and best practices.

What we’re looking for:

• 5+ years of professional experience in Android development.
• Strong skills in Kotlin and familiarity with modern Android architecture patterns (MVVM, MVI, or Clean Architecture).
• Understanding of secure app development principles; experience with Keystore or Secure Element is a plus.
• Experience integrating REST APIs and handling network communication.
• Strong focus on code quality, testing, and maintainability.
• Collaborative mindset and willingness to learn from and support other team members.
• 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.
