Join the team behind one of the world’s leading open-source file sync and collaboration platforms.

At Nextcloud, we empower users to take control of their data — securely, privately, and transparently. With a distributed team of 140 across 24 countries, we work remotely and foster a collaborative, trust-based culture built around our commitment to open source and digital sovereignty.

We’re looking for a passionate and skilled macOS Desktop Engineer to help  
shape the future of our Desktop Client — a core product relied on by millions of users worldwide. As part of our Desktop team, you’ll play a key role in building privacy-respecting, reliable, and high-performance sync software on macOS.

## Tasks

*   Improve and maintain the Qt/C++ cross-platform desktop sync client. 
*   Develop macOS-specific extensions using Swift and Objective-C++ (File Provider, AppKit). 
*   Troubleshoot and resolve complex sync issues across diverse systems. 
*   Participate in code reviews, community forums, and open-source development  
processes. 
*   Collaborate with fellow developers, designers, and community members across time zones. 
*   Contribute to the evolution of a secure and user-respecting alternative to  
proprietary cloud services.

## Requirements

*   Proven experience with Swift, C++, and Objective-C++ (non-ARC). 
*   Solid grasp of Qt, AppKit, FileProvider, and Finder Sync. 
*   Familiarity with Xcode, CMake, Git, GitHub (PHP is a plus). 
*   Strong understanding of multithreading and concurrency (GCD, Swift Concurrency). 
*   Knowledge of macOS internals including launchd, fileproviderd, code signing,  
and app distribution. 
*   Comfort working independently in a remote, open-source team. 
*   Proficiency in English is required; additional languages are a plus.

**Nice to have**

*   Experience with Realm or other embedded databases. 
*   Background in cloud storage, file sync, or secure application development. 
*   Contributions to open-source projects or active participation in relevant  
communities.

## Benefits

*   Ein internationales Team mit viel Herzblut für die Philosophie von Open-Source
*   Ein innovatives Produkt, das Millionen von Nutzern weltweit begeistert
*   Attraktive Vergütung und flexible Arbeitszeiten
*   Zeit für persönliche Entwicklung und ein jährliches Budget für Weiterbildung
*   Entwicklungsmöglichkeiten und Perspektive für die Zukunft
