Senior Android Developer (m/f/d)

Staff / Senior Android Developer (m/f/d) – Digital Identity Wallet

Fully-remote from Germany, as soon as possible, initially limited until December 2026 (planned to be converted into a permanent contract afterwards)

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) 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:

• Strong understanding of the European Digital Identity Wallet (EUDI Wallet) ecosystem, including the core protocols and standards for digital credential issuance, presentation, and verification (e.g., OpenID4VCI, OpenID4VP, W3C Verifiable Credentials, OAuth 2.0/OpenID Connect), as well as the eIDAS 2.0 framework, Architecture and Reference Framework (ARF), and Implementing Acts.
• Experience building secure mobile applications that balance security, privacy, and usability, with knowledge of EUDI Wallet reference implementation libraries and the ability to develop compliant Android solutions (cross-platform Android/iOS experience is a strong plus).
• Excellent communication skills, with the ability to translate product requirements into robust engineering solutions and effectively collaborate with product, design, and engineering teams.
• Collaborative, mission-driven team player who is invested in the success of the European Digital Identity Wallet initiative and enjoys working in cross-functional, international teams.

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 from Germany
• Access to conferences, team events and a supportive work culture.
