Site Reliability Engineer (Senior or Staff), Atlas

ABOUT THE ROLE MongoDB’s Atlas platform is the world’s most widely deployed, globally distributed, multi‑cloud data platform. As a Senior or Staff Site Reliability Engineer on the Atlas SRE team, you will be at the forefront of building and operating the infrastructure that powers millions of customer applications, from AI‑native startups to Fortune 100 enterprises. Your work will directly influence the reliability, performance, and scalability of Atlas, ensuring that every customer can run their most critical workloads with confidence. Whether you work from our New York City headquarters or from a location in the Eastern or Central time zone, you will collaborate with cross‑functional teams to design resilient systems, automate operations, and drive continuous improvement across a multi‑cloud environment. WHAT YOU'LL DO You will design and implement large‑scale, multi‑cloud solutions that underpin Atlas, leveraging AWS, Azure, and Google Cloud to deliver high availability and low latency for customers worldwide. You will own the full lifecycle of critical services, from architecture and deployment to monitoring, incident response, and post‑mortem analysis. Your day‑to‑day responsibilities will include automating repetitive operational tasks, developing tooling that reduces manual toil, and collaborating with software engineering teams to embed reliability best practices into the development pipeline. You will participate in a 24/7 on‑call rotation, diagnosing and resolving incidents that affect the Atlas fleet, and you will lead blameless post‑mortems to drive systemic improvements. Finally, you will mentor junior SREs, share knowledge across the organization, and contribute to the evolution of our reliability culture. WHAT YOU'LL NEED You bring at least five years of experience running critical systems at scale, with a proven track record of delivering reliable, high‑performance services in a production environment. You are comfortable operating a large‑scale Linux environment, understanding low‑level fundamentals, and you have deep expertise in at least one modern programming language such as Go, Python, or Ruby. Your background includes designing and managing infrastructure in a multi‑cloud setting, and you are familiar with core web and network protocols including HTTP, TLS, and DNS. You have a customer‑first mindset, prioritizing automation over manual processes, and you thrive in a fast‑paced, highly collaborative environment. U.S. citizenship is required for this role.
