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.

MongoDB Cloud Team is a diverse collection of individuals working together to provide MongoDB in the cloud at global scale. The Cloud Team is responsible for several services including MongoDB Atlas - our database as a service offering and fastest growing product, MongoDB Realm- our serverless platform offering that allows developers to build apps on MongoDB without managing any infrastructure, and our newest offering, Atlas Data lake

The Cloud Site Reliability Engineering Team designs and builds the global infrastructure on which we deploy our services. As our customers grow and globalize, our services must satisfy demands for low-latency requests around the globe, and comply with various data sovereignty requirements. The SRE Team’s mission is to build this increasingly complex infrastructure, while continually lowering the operational burden associated with it, and increasing our internal visibility into the health of the system. We are strong believers in infrastructure-as-code and self-healing systems. The SRE Team is fully integrated with the Cloud Software Engineering teams - most significant features we build require new code from both “SWEs” and “SREs”, and the teams work closely together with a soft and traversable boundary between their areas of responsibility. Our infrastructure encompasses a wide variety of technologies, but we make extensive use of AWS, Terraform, Chef, Prometheus, Python and Go.

This role is based out of Amsterdam, Netherlands.
