> Build scalable security controls and services for MongoDB Atlas multi-cloud infrastructure, spanning runtime protection, cloud security posture, identity, observability, and secure infrastructure automation. The role requires 5+ years of software or SRE experience, strong Linux and networking fundamentals, cloud expertise, and Kubernetes security experience.

## Job Description

## Responsibilities
- Design and build core security primitives and services that protect MongoDB Atlas compute, networking, and identity across AWS, Azure, and Google Cloud.
- Build secure-by-default infrastructure using Linux security mechanisms including AppArmor, SELinux, seccomp, cgroups, Kubernetes, and eBPF to enforce runtime policies and provide deep system visibility.
- Develop APIs, automation, and tooling to manage security posture at scale, including CSPM, vulnerability management, and workload identity.
- Provide monitoring, logging, and alerting pipelines integrating with Grafana, Splunk, and VictoriaMetrics.
- Integrate security into CI/CD and infrastructure-as-code workflows using Terraform so controls are versioned, reviewed, and deployed like other code.
- Lead complex projects end-to-end, from discovery and design through implementation, rollout, and long-term ownership.
- Collaborate with SRE, platform, and product engineering teams to define secure architectures for infrastructure and services.

## Requirements
- 5+ years of experience in software engineering, site reliability engineering, or similar roles, preferably with relevant security work.
- Proficiency in at least one programming language: Java, Go, Rust, Python, C, or C++.
- Experience with Terraform and infrastructure-as-code automation.
- Deep understanding of Linux and networking concepts, including low-level fundamentals.
- Experience building security-related features or platforms such as runtime monitoring, CSPM, or vulnerability management.
- Experience with AWS, Google Cloud, or Azure and their security best practices and building blocks.
- Hands-on experience with Kubernetes and its security ecosystem.
- Systems mindset covering failure modes, performance, observability, operability, security, and correctness.
- Strong communication skills and ability to explain complex security concepts and tradeoffs to technical and non-technical stakeholders.

## Nice-to-haves
- Experience with Kubernetes security tools and frameworks such as RBAC, OPA/Gatekeeper, Kyverno, eBPF, Falco, or Tetragon.

## Compensation and Benefits
- MongoDB provides a supportive and enriching culture focused on employee growth and business impact.
