Staff/Senior Security Software Engineer or SRE - Infrastructure Security

We are looking for experienced Software and Site Reliability Engineers to help secure the foundation of MongoDB Atlas, our globally distributed, multi-cloud database platform running across AWS, GCP and Azure.

This is a builder role, focusing on security tooling and observability, runtime detection, hardening policies, and infrastructure-as-code guardrails that protect our massive infrastructure.

Some of the things we're working on:

• Building secure-by-default infrastructure leveraging Linux, eBPF and Kubernetes security mechanisms, and implementing runtime detection and monitoring.
• Developing our in-house CSPM (Cloud Security Posture Management) and Vulnerability Management platforms.
• Integrating security directly into our CI/CD workflows and Terraform pipelines.

We're looking for engineers with a strong systems mindset who have some of:

• 5+ years of experience in SWE, SRE, or similar roles with some relevant security experience.
• Proficiency in one programming language: Golang, Rust, Python, C/C++ etc.
• Deep understanding of Linux internals, networking, and Kubernetes security.
• Familiarity with one major cloud provider (AWS, GCP or Azure.)
• A builder's mentality: you think about failure modes, observability, and operability alongside security and correctness.
