• Develop and maintain Chef cookbooks, recipes and policies, and manage Chef Infra Server and Chef Automate.
• Automate OS builds, hardening, patching and application deployments across Linux and Windows estates.
• Manage inventories, environments and secrets securely, e.g. with Ansible Vault, HashiCorp Vault or Chef data bags.
• Run Ansible Automation Platform (AWX / Tower) job templates, workflows and RBAC.
• Integrate configuration management into CI/CD pipelines with automated testing (Molecule, Test Kitchen, InSpec).
• Enforce CIS benchmarks and compliance-as-code to support PCI-DSS, SOC 2 and ISO 27001 audits.
• Provision cloud and on-premises infrastructure alongside Terraform.
• Support migrations from Chef to Ansible, or between platform versions, where programmes require it.

• Write clear runbooks and documentation, and mentor engineers on automation best practice. Requirements Requirements
• 5+ years in infrastructure, DevOps or platform engineering, with 3+ years hands-on with Ansible and Chef in production.
