Infrastructure Engineer Two Jobs in Merton, WI (NOW HIRING)

Are you looking for the ideal hands-on opportunity? Here, you’ll have real ownership, not just tickets.

In your role as a Cloud Infrastructure Engineer, you will design, implement, and operate the Kubernetes-based cloud-native platform—so you can see your decisions directly improve scalability, availability, and security.

Position Summary:

Delta Defense is seeking a hands-on Cloud Infrastructure Engineer with strong expertise in Kubernetes and modern CI/CD practices. Join our infrastructure team in a role where you will design, implement, and operate secure, scalable, and highly available cloud-native platforms that support multiple engineering teams.

In this role, you’ll help manage the full lifecycle of containerized applications—from image build and deployment through observability, performance validation, and reliability improvements—while helping strengthen a resilient, well-governed multi-tenant platform environment.

Why your work in this role matters:

• You’ll help ensure the reliability, security, and scalability of our core platforms.
• You’ll influence how infrastructure is built and operated as the organization grows.
• You’ll work across teams to enable faster, safer software delivery.
• You’ll have opportunities to improve systems, processes, and tooling—not just maintain them.

Essential Duties and Responsibilities:

• 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.

Skills/Abilities and Education Requirements:  

• Applicants must be authorized to work for ANY employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time.
• A high school diploma or equivalent is required. 
• 2–5+ years of experience in cloud infrastructure, DevOps, or SRE roles.
• Hands-on experience managing Kubernetes clusters in production, including secure multi-tenant configurations.
• 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.
• Proficiency in Python or similar scripting language for infrastructure automation.
• Working knowledge of networking, Kubernetes security, and deployment strategies (rolling, blue-green, or canary).
• Practical experience with load testing and performance analysis.
• Demonstrates the Core Values of Delta Defense, LLC.
