Site Reliability Engineer 3
Confirmed on the employer's own hiring board on Oct 24, 2026. First seen by Alion on Apr 21, 2026. MongoDB scores B on the Alion truth index.
The Site Reliability Engineering team designs and builds the global infrastructure on which we deploy our services, focusing on the above mentioned flagship MongoDB Atlas platform. 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 all the other engineering teams, and the teams work closely together with a soft and traversable boundary between their areas of responsibility.
We are looking to speak to candidates who are based in New York City for our hybrid working model.
