Job Description: Infrastructure Engineer – Chef Configuration Management
Position Overview
We are seeking an experienced Infrastructure Engineer with extensive expertise in Chef configuration management tools and Red Hat Linux systems. The ideal candidate will play a key role in designing and maintaining automated configuration management solutions using Chef, building highly available systems, and ensuring seamless infrastructure operations in a 24/7 environment.
Key Responsibilities – Chef Configuration Management
• Manage Chef Infrastructure: Install, configure, and maintain Chef servers, Chef clients, and associated components, ensuring high availability and scalability.
• Develop and manage Chef artefacts: Create, test, and manage custom cookbooks, recipes, roles, run-lists, data bags, templates, and attributes to automate infrastructure configuration and management.
• Maintain compliance using Chef Automate: Use Chef Automate to monitor and enforce compliance, ensuring adherence to security and organisational policies across all systems.
• Optimise Chef solutions: Continuously review and optimise Chef implementations to improve efficiency, minimise system downtime, and enhance overall automation workflows.
Integrate Chef with AWS: Automate the deployment and management of AWS resources (e.g., EC2 instances, VPCs, EBS volumes) using Chef cookbooks and recipes.
• Implement high availability for Chef: Design and implement high-availability Chef server clusters, ensuring business continuity and disaster recovery capabilities.
• Infrastructure as code (IaC): Design, implement, and maintain Terraform modules to provision and manage cloud resources such as EC2 instances, VPCs, EBS volumes, and security groups.
• Streamline infrastructure management: Leverage Chef's configuration drift detection to ensure system consistency and resolve discrepancies promptly.
• Integrate Chef with other tools: Collaborate with other teams to integrate Chef with DevOps tools like Git, GitHub, Ansible, and CI/CD pipelines for seamless automation.
• Extend Chef functionality: Develop custom Chef resources, libraries, and plugins to address specific business requirements and enhance functionality.
• Troubleshoot Chef-related issues: Resolve issues such as dependency management, cookbook conflicts, node communication errors, and performance bottlenecks.
General Responsibilities
• Design, implement, and manage Red Hat Linux systems in both on-premise and cloud environments.
• Ensure infrastructure systems are optimised for high availability, performance, and scalability.
• Participate in a 24/7 on-call rotation to provide critical support for infrastructure operations.
