* 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.
