iOS Developer (all genders) – Digital Identity Wallet

ABOUT US

Common Codes is leading the development of Germany’s EUDI Wallet on behalf of the Federal Ministry for Digital Transformation and Government Modernisation. Our mission is to build secure, privacy-first and trustworthy digital public infrastructure. Together with partners from government, business, research and civil society, we are creating an open and interoperable ecosystem for digital credentials. The EUDI Wallet will enable public authorities and companies to offer new digital services, simplify processes and develop applications based on verifiable digital information. For citizens, it will provide a simple and secure way to identify themselves, store digital credentials and share only the information required in a specific situation. Whether opening a bank account, applying to a university or proving their age, users will remain in control of their personal data. By building this infrastructure, we are laying the foundation for a more accessible, efficient and trustworthy digital society. The EUDI Wallet will reduce bureaucratic barriers, make digital services easier to use and strengthen digital sovereignty in Germany and Europe
