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
