Contract – Cloud Infrastructure Engineer

Rate: Open

Location: Chicago, IL

Hybrid: 3 days onsite, 2 days remote

Duration: 6+ months

• We are unable to provide sponsorship for this role*

Qualifications

• 3-5+ years of experience in the following:
• Infrastructure-as-Code using Terraform, AWS CloudFormation/Ansible; provisioning and managing cloud resources across AWS and Azure.
• Cloud-native container orchestration: Kubernetes (EKS preferred)/Rancher-k8s, including cluster operations, workload deployment, and project/namespace governance.
• CI/CD pipeline development using tools such as GitHub Actions, AWS CodePipeline, GitLab CI, or Azure DevOps Pipelines.
• 2–3+ years of experience in the following:
• GitOps delivery patterns using ArgoCD or equivalent; managing declarative application state from git repositories.
• Secrets management and PKI: HashiCorp Vault configuration and operations / AWS KMS & Secrets Manager.
• 1–3+ years of experience in the following:
• Observability and monitoring: Prometheus, Grafana, Elasticsearch, AWS CloudWatch/CloudTrail or equivalent enterprise logging and alerting tooling.
• Working knowledge of enterprise networking: ingress controllers (Traefik or equivalent), load balancers, security groups, and certificate-based authentication.
• Familiarity with GitHub Copilot or AI-assisted developer tooling integration within a CI/CD or developer environment context.
• Strong UNIX/Linux fundamentals; comfortable operating in terminal-first infrastructure environments.
• Experience working from a backlog in a planned work management tool (Jira or equivalent); ability to operate autonomously against a defined delivery roadmap.

Responsibilities

• Maintain and extend Infrastructure-as-Code (IaC) patterns using Terraform for both AWS and Azure environments within the Enterprise Lab Zone.
• Operate and evolve the Enterprise Lab management plane: EKS cluster configuration, GitLab CI/CD runners, ArgoCD deployments, Vault PKI, Traefik ingress, and AWS CodePipeline.
• Resolve outstanding Azure/Entra billing and governance issues; bring Azure under the same unified governance model as AWS.
• Maintain resource tagging compliance, cost visibility, and sandbox lifecycle controls (90%/100% cost thresholds) across both cloud providers.
• Build and populate the Architecture Pattern Catalog: approved IaC patterns enabling users to provision sandbox environments without manual OTSI Engineering intervention.
• Implement self-service cloud catalog to provision compute resources to sandbox environment(s).
• Instrument and validate the Deployment Time SLA — the time from session start to a provisioned environment — targeting a threshold that makes 1-hour and 1-day lease durations frictionless for end users.
• Contribute developer environment patterns to the catalog to expand the Enterprise Lab user base beyond infrastructure-only experiments.
