The Opportunity: As part of the Clairvoyant program, you will build and support the backbone of a mission-critical, cloud-native ecosystem — a scalable software-hosting and data-dissemination platform designed to accelerate the deployment of advanced analytics. You will bridge complex mission requirements and high-performance automated infrastructure, owning everything from secure pipeline design to cloud resource optimization. As a DevOps / Infrastructure / DevSecOps Engineer on an AWS-based, Kubernetes-native environment, you will:

  • Architect Resilience: Design and maintain scalable RKE2/Kubernetes infrastructure on AWS with high availability and fault tolerance.
  • Orchestrate Delivery: Build and refine CI/CD pipelines using GitLab CI/CD, ArgoCD, Jenkins, and Helm for seamless code-to-cloud transitions.
  • Secure the Stack: Integrate automated security scanning (Trivy, SonarQube) and enforce compliance with government security standards throughout the development lifecycle.
  • Optimize Performance: Identify bottlenecks and engineer solutions across cloud and container environments, from cluster tuning to artifact management.

Responsibilities:

  • Develop features to automate, scale, test, and secure a Kubernetes-based infrastructure running on AWS with RKE2.
  • Build, optimize, and maintain CI/CD pipelines using GitLab CI/CD, Jenkins, and ArgoCD, supporting automated build, test, scan, and deployment workflows.
  • Author, template, and manage Helm charts for application and infrastructure deployment across multiple environments.
  • Build and maintain hardened Docker container images, including STIG-compliant base images, optimized Dockerfiles, and integration with Harbor and CI/CD pipelines.
  • Manage and scale RKE2 Kubernetes clusters, including workload scheduling, networking, RBAC, secrets management, and cluster lifecycle operations.
  • Administer Harbor (container registry) and Nexus (artifact repository), ensuring availability, security, and pipeline integration.
  • Integrate Trivy and SonarQube into pipelines; remediate findings in coordination with security stakeholders.
  • Enhance performance monitoring; identify bottlenecks and optimize cloud infrastructure and resource utilization.
  • Author Python and Bash automation scripts to reduce toil and support infrastructure lifecycle management.
  • Maintain technical documentation, runbooks, and architecture diagrams.

Qualifications:

Required:

  • Current TS/SCI clearance with Polygraph.
  • Bachelor's degree in Computer Science or related field, or equivalent experience.
  • 3+ years (mid-level) or 6+ years (senior-level) in DevOps, Infrastructure, or DevSecOps in a cloud environment.
  • Advanced proficiency in Python and/or Bash scripting for automation and operational support.
  • Strong Linux/Unix command line proficiency, preferably on RHEL-based systems.
  • Experience building and maintaining CI/CD pipelines using GitLab CI/CD, Jenkins, ArgoCD, and Helm.
  • Strong proficiency with Docker — writing Dockerfiles, building hardened images, and integrating builds into pipelines.
  • Hands-on Kubernetes experience — cluster operations, workload management, RBAC, networking, and troubleshooting.
  • Familiarity with agile methodologies and ability to operate effectively within a distributed team.
  • Ability to travel up to 5% of the time.

Desired:

  • Experience with AWS services and cloud-native infrastructure patterns.
  • Hands-on experience with Terraform for cloud resource provisioning and IaC.
  • Experience with RKE2 or other enterprise Kubernetes distributions in air-gapped or restricted environments.
  • Familiarity with Harbor, Nexus, Trivy, and SonarQube in a pipeline context.
  • Experience with Cilium for Kubernetes network policy and cluster networking.
  • Experience with Packer or Ansible for image and configuration management.
  • Relevant certifications: CKA/CKAD/CKS, AWS DevOps Professional, or CompTIA Security+

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
