DevOps Engineer

• We are seeking a DevSecOps engineer to help secure our AWS EKS Kubernetes environment and CI/CD pipeline as we prepare for a FedRAMP High audit.
• We run 350 container images on AWS EKS. FedRAMP expertise is not required, but deep familiarity with container technology and security is essential.

Essential Job Functions:

• Upgrade vulnerable containers in collaboration with the DevSecOps team, testing and promoting updates to production.
• Apply cloud hardening and maintain Terraform/Ansible code to enforce security settings across AWS services and Kubernetes nodes per STIG and CIS benchmarks.
• Design and maintain automated container patching pipelines including base image refresh, rebuild triggers, and automated PR generation.
• Build and maintain vulnerability scanning workflows using Grype and/or Trivy as pipeline gates blocking promotion of images exceeding CVE thresholds.
• Build and manage Argo Workflows orchestrating end-to-end patch automation from scanning through remediation, rebuild, and deployment.
• Write Python-based tooling supporting pipeline logic, scan result parsing, notification routing, and patch orchestration.
• Own GitHub-based development workflow: branch strategy, PR creation/review, code quality standards, and merge gate enforcement.
• Conduct code reviews ensuring changes meet security, quality, and operational standards before production promotion.
• Maintain production readiness practices including testing, peer review, rollback procedures, and deployment validation.
• Analyze Kubernetes IAM configurations and RBAC policies to identify overprivileged roles, misconfigurations, and deviations from least-privilege principles.
• Review and harden Kubernetes network setup and segmentation including network policies, namespace isolation, and inter-service communication controls.
• Audit certificate usage across the cluster and pipeline, ensuring proper issuance, validity, and automated rotation; verify secrets are rotated on schedule and not hardcoded or overexposed.
• Scan codebases, repos, and infrastructure configs for exposed secrets using open source tools such as Hedgehog and equivalent secret detection utilities.
• Scan S3 buckets for exposed secrets and sensitive data, remediating findings and implementing preventive controls.
• Review network, WAF, and Istio logs to map existing traffic flows and service communication patterns in preparation for network segmentation and a deny-by-default lockdown posture.
• Develop automations for WAF rule creation and tuning based on observed traffic patterns and threat intelligence.
• Leverage Claude to accelerate security research, organize remediation plans, and develop Python-based tooling for non-production-impacting automation and analysis tasks.
