Staff Site Reliability Engineer, Infrastructure Security

Overview

As a Security Software Engineer in the Infrastructure Security team, you design and build core security primitives for MongoDB Atlas across AWS, Azure, and GCP. You will implement secure-by-default infrastructure using Linux security mechanisms, Kubernetes, and eBPF, enabling runtime policy enforcement and deep visibility. You will develop tooling and APIs to scale security posture management and integrate security into CI/CD and IaC workflows. You’ll lead end-to-end security projects and collaborate with SRE, platform, and product teams to architect secure infrastructure.
