## Description

Mastercard is seeking a Lead Chef Automation Engineer to design and build scalable automation solutions for large, hybrid infrastructure environments. 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.

**Benefits**

- Insurance (including medical, prescription drug, dental, vision, disability, life insurance)

- Flexible spending account and health savings account

- Paid leaves (including 16 weeks of new parent leave and up to 20 days of bereavement leave)

- 80 hours of Paid Sick and Safe Time

- 25 days of vacation time and 5 personal days, pro-rated based on date of hire
