Description
We are seeking a Principal Engineer with strong experience in infrastructure automation, configuration management, and CI/CD pipelines. In this leadership role, you will help define and execute the technology roadmap for configuration management across bare metal servers and virtual machines. You will guide pull request review processes, establish CI/CD best practices, and scale and maintain automation workflows that support high availability and reliable operations.
Core Focus: Chef Automation, Bare Metal and VM Orchestration, CI/CD Design and Maintenance
Work Pattern: Multi-Cloud and Bare Metal Infrastructure at Global Scale
Governance: Effective PR Reviews, Code Quality, and CI/CD Pipeline Automation
Key Responsibilities
Configuration Management and Provisioning
- Scale, maintain, and support enterprise Chef cookbooks, custom resources, and environments across bare metal and VM infrastructures.
- Standardize system configurations and automate bare metal provisioning and virtual machine lifecycles to promote high consistency across fleets.
- Support infrastructure testing best practices, including tools such as Test Kitchen, within Chef development cycles.
CI/CD Automation and Jenkins Pipelines
- Scale, maintain, and optimize Jenkins automation pipelines for continuous integration and continuous deployment of infrastructure code.
- Automate testing, validation, and deployment workflows to reduce manual intervention in server configuration updates.
- Integrate security scanning, automated linting, and rollback strategies into core CI/CD pipelines.
Code Review and Engineering Governance
- Lead consistent Pull Request review processes that support code quality, security compliance, and alignment with engineering standards.
- Establish operational guidelines, code styling standards, and testing frameworks for team infrastructure repositories.
- Mentor engineers at different career stages on infrastructure-as-code principles, effective PR contributions, and automation workflows.
Bare Metal and VM Operations
- Drive lifecycle management, hardware integration, and OS configuration across large-scale physical bare metal nodes and hypervisors.
- Troubleshoot complex hardware, virtualization layer, network, and OS-level issues in high-density production environments.
- Help keep the infrastructure fleet secure by supporting regular OS upgrades, applying critical security patches, and contributing to priority security programs.
- Participate in a shared on-call rotation, with appropriate support and escalation processes, to help resolve critical operational issues and support site reliability.
Requirements
- 12+ years of hands-on experience with infrastructure automation and configuration management, including Chef or similar tools for cookbook development, custom resources, and automated server orchestration.
- 8+ years of experience managing, provisioning, and maintaining bare metal and/or enterprise virtualized infrastructure.
- 8+ years of experience building and maintaining CI/CD pipelines for infrastructure deployment and automated testing, preferably with Jenkins.
- 8+ years of experience establishing Git workflows, managing repository standards, and conducting thorough Pull Request code reviews.
- 8+ years of strong track record of automating complex workflows and scaling multi-cloud or hybrid compute environments.
- 8+ years of experience setting technical direction and driving engineering excellence across cross-functional engineering teams.
