Job summary

MongoDB Inc. is seeking a senior staff-level InfraSec engineer to harden Linux hosts and container workloads, implement multi-cloud security controls, and drive automated CSPM and identity tooling. You will write production-grade code and use Terraform to deploy security controls as code.

The role supports US-based offices or remote work in the United States. You’ll collaborate across teams to shape architecture, threat modeling, and operational reliability at Atlas scale.

Responsibilities

• Harden hosts and containerized workloads using Linux security mechanisms (AppArmor, SELinux, seccomp, cgroups) and eBPF-based tooling.
• Secure containerized infrastructure across multi-cloud environments via RBAC, network policies, admission controls, and runtime threat detection.
• Build and manage automated services for CSPM, workload identity, vulnerability management, and access controls across AWS, Azure, and GCP.
• Write production-quality code and leverage Terraform to version, test, and deploy security controls as code.
• Build real-time security monitoring, logging, and alerting systems to detect anomalies and track security posture at Atlas scale.
