Lead, Query Engineer (EMEA)


The database market is massive (the IDC estimates it to be $89B+ by 2024!) 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.

Join the MongoDB Query team, and help us build a world-class distributed open source query engine. Our team is responsible for maintaining MongoDB's unique query system, the beating heart of the MongoDB server. We are responsible for the MongoDB Query Language and the lifecycle of each query, from parsing to optimisation to plan selection and execution. We are responsible for the aggregation framework, which allows arbitrary transformation of query results before they are passed back to the client; we maintain the data update, delete and insertion subsystems; we built MongoDB's real-time "change stream" event notification system, and we are responsible for the code that targets and merges queries across a distributed MongoDB cluster.

Our global team is growing fast, and we are looking for leaders as part of this expansion. The query team is based in New York City and Dublin, and we are building a presence around our offices in the Bay Area. We support office-based as well as remote work, and align projects with convenient work hours for each time-zone.

We have tons of interesting problems to solve with direct impact on users, particularly in the areas of transactional, time-series, and analytical workloads. As we grow, we need engineering managers to help us structure the organisation, improve technical processes, provide career mentorship, guide the product roadmap, and manage projects.
