Infrastructure Automation Engineer

About This Role

This engineering role focuses on designing, building, and maintaining the infrastructure-as-code foundations that power cloud and hybrid environments. The Infrastructure Automation Engineer will create reusable Terraform modules, harden pipelines, enforce policy-as-code, and standardize infrastructure delivery across multiple teams and cloud providers. The ideal candidate brings strong software engineering discipline to infrastructure work and has shipped production-grade Terraform at scale.

Responsibilities

• Design, develop, and maintain modular, composable Terraform code that codifies the entire infrastructure estate across cloud accounts and environments
• Build a library of well-tested, reusable Terraform modules with clear interfaces, semantic versioning, and comprehensive documentation
• Implement Terraform automation pipelines using GitHub Actions, GitLab CI, Atlantis, Terraform Cloud, or Spacelift, with plan/apply gating, drift detection, and policy enforcement
• Define and enforce policy-as-code using Sentinel, Open Policy Agent (OPA), Conftest, or Checkov to prevent insecure or non-compliant infrastructure changes
• Manage Terraform state at scale with appropriate backend strategies, state locking, workspace organization, and disaster recovery patterns
• Drive multi-account, multi-region, and multi-cloud infrastructure provisioning strategies with clear isolation, naming, and tagging standards
• Implement infrastructure testing including unit tests with terraform-compliance, integration tests with Terratest, and policy tests across pull requests
• Collaborate with security, networking, and platform teams to embed guardrails directly into reusable modules and pipelines
• Standardize patterns for secrets management, identity federation, and least-privilege IAM through reusable Terraform abstractions
• Lead migrations from legacy, ClickOps, or non-IaC infrastructure into managed Terraform footprints with minimal disruption
• Drive cost optimization, tagging hygiene, and lifecycle management across the Terraform-managed estate
• Mentor engineering teams on Terraform best practices, anti-patterns, and pull-request review standards
• Maintain comprehensive runbooks, architecture diagrams, and onboarding materials for the infrastructure platform
• Stay current with Terraform, OpenTofu, and broader IaC ecosystem developments and recommend adoption where beneficial

Requirements

• Bachelor’s degree in Computer Science, Engineering, or a related field
• Five or more years of experience in cloud infrastructure or DevOps engineering, with significant Terraform focus
• Deep, hands-on expertise authoring and maintaining production Terraform across at least one major cloud provider
• Strong experience designing reusable Terraform modules with clean APIs and version discipline
