At OCULD we build solutions to shape the future of secure communication and collaboration. Our goal is to build applications which enable corporates and individuals to communicate safe and efficient. We believe we can change the way how we interact and share information by developing a unique platform for all communication needs that is secure and protects everyone’s right to privacy.

OCULD Solutions GmbH is a founder-owned startup based in Berlin. We are looking for an Android software developer responsible for the development of applications aimed at a range of Android devices including mobile phones and tablet computers. Your primary focus will be development of Android applications and their integration with back-end services. You will be working alongside other developers working on different layers of the infrastructure. Therefore, a commitment to collaborative problem solving, sophisticated design, and the creation of quality products is essential.

The Android app is aimed to support our main desktop application as a mobile sidekick, to receive fully end-to-end encrypted messages, chats, tasks and files when out of office. It extends our existing capabilities, but is in itself a new project from scratch.


  • Design and build an application for Android as a mobile sidekick for our desktop app
  • Ensure the performance, quality, and responsiveness of applications
  • Collaborate with our team to define, design, and ship new features
  • Identify and correct bottlenecks and fix bugs
  • Help maintain code quality, organization, and automatization

Skillset we are looking for

  • Profound experience working in native Android development projects is essential
  • Excellent knowledge of the Android SDK
  • Basic understanding of cryptography
  • Understanding of REST API communication
  • Understanding of Keychain and other Android security framework issues
  • Very good working knowledge in German and English

We offer a competitive compensation, no bullshit get-things-done attitude, and a commuter friendly location in the middle of Berlin. Furthermore, we will set you up with your ideal development environment to facilitate your best work and least frustration.

If needed, we will also take care of your work visa and help with relocation/accommodation.

The position is available immediately and for a duration of 1-3 months on a freelance basis, but full time positions are also considered for the right candidate.

If solving thrilling problems such as future-proof security, smart encryption and key management sounds like an interesting challenge to you, we want to hear from you.
