Senior Software Engineer, Core Server

The worldwide data management software market is massive (IDC forecasts it to be $138 billion by 2026!). At MongoDB we are 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.

The MongoDB Server Team builds the open source database at the core of our business. We provide the rich feature set needed for a document database that offers strong consistency and a high degree of scalability. We have the unique challenge of enabling our Cloud Team to run the database as a service, while delivering an on-premises product that delights both enterprise and community users. We range in experience from new college grads to seasoned staff engineers, but we share a love of computer science fundamentals and a rigorous commitment to quality. The Server Team presents endless opportunities for learning and growth, and many team members have chosen to build their careers here.

This role can be based out of our NYC office or remotely from anywhere in North America.

Storage Execution Team

The MongoDB Storage Execution team's mission is to research and develop new algorithms for storing data, maintain a pluggable protocol for MongoDB storage engines, and provide a comprehensive framework for managing concurrent, transactional access to data stored locally within a MongoDB database instance.

Our team champions a strong culture of inclusivity, diversity, and collaboration. As a team member, you will contribute to crafting and maintaining the nexus of the different server components, connecting its query system and distributed replication system to its underlying storage engines. Ongoing work includes improvements to support time series data, memory allocator improvements, new indexing algorithms, and implementations for admission control and flow control for the server.

Additional Requirements 

• Experience in programming, debugging, and performance tuning distributed and/or highly concurrent software systems
  

Sharding Team

The MongoDB Sharding Team builds infrastructure and tools that allow users to scale their workloads beyond the capabilities of a single node. They take pride in building elegant abstractions for difficult distributed systems problems which enable users of MongoDB to focus on working with data instead of worrying about where it resides or how it’s accessed. As a result of this, the projects delivered by the Sharding Team have enormous impact and represent solutions to the most difficult data challenges faced by our largest clients.

To achieve their goals, the sharding team designs and builds machinery that transforms independent query
