Delta Defense, LLC is looking for a Cloud Infrastructure Engineer to design, implement, and operate secure, scalable, and highly available Kubernetes-based cloud-native platforms. You will be essential in supporting multiple engineering teams, managing the full lifecycle of containerized applications, and strengthening a resilient, well-governed multi-tenant platform environment.
What You'll Do
- Design, deploy, and manage production Kubernetes clusters, including workload scheduling, resource quotas, network policies, ingress/egress controls, and RBAC.
- Develop and maintain declarative deployment patterns using Helm, Kustomize, and Kubernetes operators.
- Build and optimize CI/CD pipelines using Infrastructure as Code and GitOps principles, including version-controlled changes, automated validation, and rollback strategies.
- Provision and manage infrastructure using tools such as Terraform or Crossplane, applying best practices for immutability, idempotency, and state management.
- Build secure, efficient container images using multi-stage builds and vulnerability scanning; manage image versioning and promotion across environments.
- Implement observability solutions using tools such as Prometheus, Grafana, and OpenTelemetry; support service level indicators (SLIs), service level objectives (SLOs), and actionable alerting strategies.
- Conduct load testing and resilience validation to support performance tuning, failure analysis, and capacity planning.
- Perform Linux system administration, including system hardening, troubleshooting, and OS-level performance tuning.
- Support stateful workloads (e.g., Postgres, MySQL, Redis, Kafka), including backup and restore considerations and performance implications.
- Participate in on-call rotation and incident response, contributing to root cause analysis and continuous reliability improvements.
- Document architecture, operational procedures, backup and recovery processes, and infrastructure lifecycle plans.

- Experience building and maintaining CI/CD pipelines and working with Infrastructure as Code tools such as Terraform.
- Strong containerization experience, including image optimization and security practices.
- Solid Linux administration skills and systems troubleshooting experience.
