Title and Summary

Lead Chef Automation Engineer

Overview

The Lead Chef Automation Engineer is a hands-on technical leader responsible for designing and building scalable automation solutions for large, hybrid infrastructure environments. This role focuses on creating reusable automation frameworks using Chef, Infrastructure as Code (IaC), and DevOps practices to deliver secure, consistent, and self-service infrastructure capabilities.

The ideal candidate is a strong DevOps or platform engineer with deep hands-on Chef experience who enjoys building automation solutions at scale rather than performing manual infrastructure operations.

Key Responsibilities
Design, develop, and maintain Chef cookbooks, recipes, Policyfiles, and automation frameworks across cloud and on-premises environments.
Build and maintain Chef Automate capabilities for configuration management, compliance, reporting, and fleet management.
Develop reusable automation libraries, templates, and patterns that standardize infrastructure configuration and provisioning.
Integrate automation with CI/CD pipelines, secrets management, artifact repositories, APIs, and governance controls.
Build automated testing and validation using Test Kitchen, InSpec, ChefSpec, and related tools.
Partner with cloud, platform, security, and SRE teams to establish configuration baselines, security standards, and compliance policies.
Develop and support Infrastructure as Code using technologies such as Terraform, CloudFormation, and ARM/Bicep.
Troubleshoot complex automation and configuration issues across hybrid environments.
Contribute to broader platform engineering capabilities, including self-service infrastructure, GitOps, and automated remediation.
Help establish engineering standards, reusable automation patterns, and platform architecture.
Required Qualifications
Strong experience in DevOps, platform engineering, infrastructure automation, or configuration management.
Deep hands-on experience with Chef Infra, including cookbook development, Policyfiles, Test Kitchen, and InSpec.
Experience supporting large-scale configuration management environments using Chef Server, Chef Automate, or similar technologies.
Strong understanding of Linux, operating system configuration, hardening, and lifecycle management.
Experience working across cloud and on-premises infrastructure, including AWS, Azure, GCP, VMware, or Hyper-V.
Strong scripting or programming skills with Ruby, Python, Bash, or PowerShell, with Ruby particularly relevant to Chef.
Experience integrating automation into CI/CD environments such as GitHub Actions, GitLab, Jenkins, or Azure DevOps.
Strong understanding of Git-based development, testing, code review, and version-control practices.
Ability to diagnose and resolve complex infrastructure and automation problems.
Preferred Qualifications
Experience with Chef Habitat and/or Chef Automate.
Experience with Terraform or other Infrastructure as Code platforms.
Familiarity with policy-as-code technologies such as OPA, Conftest, or Sentinel.
Experience with security hardening, compliance automation, or CIS benchmarks.
Exposure to Kubernetes, Helm, and container platforms.
Familiarity with observability technologies such as Prometheus, Datadog, Splunk, or ELK.
Experience integrating infrastructure through APIs or network automation.
