## Description

### Who We Are

MongoDB Atlas is the future of data platforms, and the Infrastructure Security (InfraSec) team, part of Site Reliability Engineering (SRE) in the CTO organization, focuses on building security infrastructure across AWS, Azure, and Google Cloud (GCP).

The InfraSec team operates on a preventative, enabling model. They develop automated guardrails and platform capabilities, integrating security directly into the platform runtime, CI/CD, and Infrastructure-as-Code (IaC) workflows. This allows engineering teams to operate securely at scale without friction.

This role can be based out of our New York City office or remotely in the eastern or central timezone.

### What You'll Do

- Hardens hosts and containerized workloads using Linux security mechanisms (AppArmor, SELinux, seccomp, cgroups) and eBPF-based tooling (Cilium, Tetragon)

- Secures containerized infrastructure across multi-cloud environments via RBAC, network policies, admission controls (Gatekeeper), and runtime threat detection

- Builds and manages automated services for Cloud Security Posture Management (CSPM), workload identity, vulnerability management, and access controls across AWS, Azure, and GCP

- Writes production-quality code and leverages Infrastructure-as-Code (Terraform) to version, test, and deploy security controls as code

- Develops real-time security monitoring, logging, and alerting systems to detect anomalies and track security posture at Atlas scale

- Leads initiatives across their full lifecycle; from threat modeling and architectural design to implementation, rollout, and long-term production reliability

### What We're Looking For

**Minimum Qualifications:**

- 5+ years in SRE, Infrastructure Engineering, or Cloud Security Engineering

- Strong coding skills in Go (Golang), Python, C, C++, or Rust

- Proven track record of building and operating large-scale distributed systems or cloud platform infrastructure

- Hands-on experience using Terraform, CloudFormation, or Ansible for automated infrastructure provisioning

- Demonstrated experience owning infrastructure in Linux, Kubernetes, and at least one major cloud provider (AWS, GCP, or Azure)

**Preferred Qualifications:**

- Practical experience with eBPF-based security tooling (Cilium, Falco, Tetragon)

- Direct ownership of Cloud Security and Workload Identity platforms

- Multi-cloud expertise spanning AWS, Azure, and GCP

- Production exposure to low-level Linux security mechanisms (seccomp, AppArmor, SELinux, cgroups)
