Role Overview

The Devops Security Engineer is a hands-on DevSecOps role responsible for securing cloud-native, multi-tenant environments operating under FedRAMP Moderate/High and NIST SP 800-53 requirements. This role focuses on preventative security, automation, and continuous compliance, embedding security controls directly into infrastructure, CI/CD pipelines, and runtime operations. The engineer will operate CrowdStrike as a core CNAPP and DevSecOps control, alongside CSPM tooling, to prevent misconfigurations, reduce risk, and maintain continuous audit readiness while working directly with customers and internal engineering teams.

Job Responsibilities

Customer Onboarding & Communication

• Coordinate external penetration testing efforts, including scoping, access, findings review, and remediation tracking.
• Use application security tools (e.g., Burp Suite) to support internal testing and remediation.

DevOps, Automation, & Preventative Security

• Implement security and compliance gates in CI/CD pipelines to prevent non-compliant infrastructure or code from reaching production.
• Enforce policy-as-code guardrails for IAM, networking, logging, encryption, and endpoint protection using Terraform.
• Ensure CrowdStrike coverage, logging, and monitoring are enforced as deployment prerequisites.
• Prevent cloud exposure by enforcing network segmentation, approved ingress/egress paths, and least-privilege access.
• Detect and remediate configuration drift using CSPM and automated workflows.
• Secure Kubernetes clusters and containerized workloads to approved security baselines.
