Senior Software Engineer, Replicated Storage Services

MongoDB’s mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, MongoDB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build and run applications anywhere—on premises, or across cloud providers. With offices worldwide and over 175,000 new developers signing up to use MongoDB every month, it’s no wonder that leading organizations, like Samsung and Toyota, trust MongoDB to build next-generation, AI-powered applications.

The MongoDB Replication Team builds infrastructure to support fault tolerance, high availability, and tunable consistency. Distributed systems is a core focus of MongoDB, and the projects delivered by the Replication Team are highly visible, typically among the flagship features for each major MongoDB release. We’re currently working on improving our API and interface boundaries so that we can meet the performance and correctness needs of the world’s most demanding enterprises while enabling new, more efficient data storage and retrieval patterns.

Our team champions a strong culture of inclusivity, diversity, and collaboration. If you want to work on a collaborative team that applies distributed systems fundamentals to deliver core features of a popular database, join us! Let’s change what’s possible for application developers, system architects, and database operators.

This role can be based out of our NYC headquarters, office hub locations, or remotely in the United States and Canada
