The database market is massive (the IDC estimates it to be $119B+ by 2025!) and MongoDB is at the head of its disruption. The MongoDB community is transforming industries and empowering developers to build amazing apps that people use every day. We are the leading modern data platform and the first database provider to IPO in over 20 years. Join our team and be at the forefront of innovation and creativity.

At Realm we help mobile developers build better apps faster by giving them a powerful alternative to SQLite. Realm on-device object database is open-source and used by more than a hundred thousand active developers. Over 65% of Fortune 1000 companies rely on Realm in their apps.

This role can be based out of our Dublin office or remotely in Europe.

The Sync team focuses on building the real-time synchronization engine for Realm Cloud platform, which automatically synchronizes data objects across all devices and the servers in real-time. Realm Sync makes it easy for mobile developers to build sophisticated mobile apps quickly with data-driven features (such as collaboration or messaging) that are responsive and performant irrespective of network status.
