About the role

Key Responsibilities
Infrastructure as Code (IaC) Development: Design, implement, and maintain infrastructure as code primarily using Terraform, but also with tools such as CloudFormation or Ansible to automate the provisioning and management of cloud-based resources.
Cloud Platform Expertise: Develop and maintain infrastructure solutions on one or more major cloud platforms (AWS, Azure, GCP), including compute, storage, networking, and security services.
Configuration Management: Utilize configuration management tools (e.g., Ansible, Puppet, Chef) to automate the configuration of servers, applications, and services.
CI/CD Pipeline Integration: Integrate infrastructure automation processes into CI/CD pipelines to enable automated deployments and infrastructure changes.
Monitoring and Logging: Implement monitoring and logging solutions to track infrastructure performance and health, ensuring reliability and uptime.
Automation Scripting: Develop custom automation scripts using scripting languages (e.g., Python, Bash) to streamline infrastructure-related tasks and workflows.
Linux Administration: Manage and maintain Linux-based servers, including system administration, package management, and performance tuning.
Containerization and Orchestration: Design and implement solutions using containerization technologies (Docker) and orchestration tools (Kubernetes) to improve application deployments and scalability.
Serverless Technologies: Develop and manage serverless solutions, particularly using AWS Lambda, and integrate them into our infrastructure and workflows.
Kubernetes Ecosystem and CNCF Landscape: Stay informed and work with various technologies in the Kubernetes ecosystem and the Cloud Native Computing Foundation (CNCF) landscape (e.g., service meshes, operators, etc.).
AWS Security and Networking: Implement and maintain secure infrastructure and network configurations within AWS environments, ensuring compliance with security policies and best practices.
Security Best Practices: Implement security best practices in all aspects of infrastructure automation, including access controls, vulnerability management, and compliance.
Performance Optimization: Identify opportunities for infrastructure optimization to improve performance, reduce costs, and enhance scalability.
Application Development with Python: Develop simple tools and applications using Python to enhance our automation efforts and address specific operational needs.
Collaboration: Collaborate closely with development teams, security teams, and other stakeholders to understand their needs and deliver effective solutions.
Documentation: Create and maintain clear, comprehensive documentation for all infrastructure automation processes, scripts, configurations, and serverless deployments.
Troubleshooting and Incident Response: Troubleshoot infrastructure-related issues, participate in incident response, and implement corrective actions.
Continuous Improvement: Continuously identify opportunities to improve infrastructure automation processes and adopt best practices.
Stay up to date: Stay informed about new technologies and trends in infrastructure automation, Linux administration, containerization, serverless technologies, Python development, Kubernetes and the broader CNCF landscape, and cloud security and networking.
