> Designs and builds scalable security controls and services for MongoDB Atlas multi-cloud infrastructure using Linux mechanisms, Kubernetes, and eBPF. Requires 5+ years experience in software/SRE with security focus, proficiency in systems programming, and cloud platforms.
## Job Description
## Responsibilities
- Design and build core security primitives and services that protect MongoDB Atlas compute, networking, and identity across **AWS**, **Azure**, and **GCP**
- Build secure-by-default infrastructure using **Linux** security mechanisms (**AppArmor**, **SELinux**, **seccomp**, **cgroups**), **Kubernetes**, and **eBPF** to enforce runtime policies and gain deep visibility into systems behaviour
- Develop APIs, automation, and tooling that manage security posture at scale (**CSPM**, vulnerability management, workload identity) and provide monitoring, logging, and alerting pipelines that integrate with our tooling (**Grafana**, **Splunk**, **Victoria Metrics**)
- Integrate security into our **CI/CD** and infrastructure-as-code workflows (**Terraform**) so that security controls are versioned, reviewed, and deployed just like any other code
- Lead complex projects end-to-end, from problem discovery and design docs to implementation, rollout, and long-term ownership
- Collaborate with **SRE**, platform and product engineering teams to define secure architectures for new infrastructure and services

## Qualifications
- **5+ years** of experience in Software Engineering, Site Reliability Engineering, or similar roles, preferably with relevant security work
- Proficiency with at least one programming language (**Java**, **Golang**, **Rust**, **Python**, or **C/C++**) and experience with infrastructure-as-code tools (**Terraform**) to automate security configurations and processes
- A deep understanding of **Linux** and networking concepts, including low-level fundamentals, and how they work together in complex systems
- Experience building security-related features or platforms such as runtime monitoring, **CSPM**, or vulnerability management
- Experience with a cloud provider (**AWS**, **GCP**, or **Azure**) and their security best practices and building blocks
- Hands-on experience with **Kubernetes** and its security ecosystem (e.g. **RBAC**, **OPA/Gatekeeper**, **Kyverno**, **eBPF**, **Falco**, **Tetragon**)
- A systems mindset: you think about failure modes, performance, observability, and operability alongside security and correctness
- Strong communication skills and the ability to explain complex security concepts and tradeoffs to both technical and non-technical stakeholders
