* 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 Dev Ops / Infrastructure / Dev Sec Ops  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 Git Lab CI/CD, ArgoCD, Jenkins, and Helm for seamless code-to-cloud transitions.

* Secure the Stack:
Integrate automated security scanning (Trivy, Sonar Qube) 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 RKE
2.

* Build, optimize, and maintain CI/CD pipelines using Git Lab 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 Sonar Qube 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 Dev Ops, Infrastructure, or Dev Sec Ops  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 Git Lab 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 Sonar Qube 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 Dev Ops Professional, or CompTIA Security+ - What You Can…
