Senior Senior Software Engineer, Catalog & Routing

The MongoDB Catalog and Routing team carries the important responsibility of hiding the complexity of building a distributed database system. They implement scalable interfaces with strong consistency guarantees that are used by other MongoDB developers to navigate and organize globally partitioned data. As a result, their work has a direct impact on the productivity of the entire organization and the success of MongoDB’s horizontal scaling strategy.

Recent work includes the ability to move unpartitionable data sets across multiple nodes without splitting a table’s keyspace, colocating cluster service in the same process in order to reduce resources consumption and operational complexity of running a sharded cluster, and the ability to perform concurrent data definition operations.

Are you excited by the prospect of tackling novel distributed systems challenges in a large scale distributed database system? We are! Join us today, and we can make databases scale for everyone.

We are looking to speak to candidates who are based in Dublin for our hybrid working model.
