Site Reliability Engineer 3

The Site Reliability Engineering team designs and builds the global infrastructure on which we deploy our services, focusing on the 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 continuously lower the operational burden associated with this complex infrastructure, increasing internal visibility into system health.

We are looking for candidates based in Dublin for our hybrid working model.

• Design, implement, and troubleshoot automation and monitoring of services that seamlessly span the globe, including multiple cloud providers.
• Become an expert in infrastructure performance, optimizing from the application level all the way through the firmware.
• Build for resilience; participate in a weekly on call rotation to keep pager incidents to zero.
• Improve infrastructure capabilities, optimizing for cost, simplicity, and maintainability.

• 3+ years of experience running a mission critical service at scale in a Linux environment.
