Full Job Posting
- Infrastructure Management & Automation: Design, implement, and maintain scalable and secure Linux-based infrastructure using Infrastructure as Code (IaC) tools like Terraform or Ansible. You will automate repetitive tasks, manage configuration, and ensure our systems are reliable and efficient. This includes downloading the Red Hat ISO, creating templates for new VMs, and making modifications for standard server needs, such as creating an Ansible user and setting nameservers. After VM deployment, you will manage configuration and hardware resources. Ansible will be used for most tasks, connecting to managed hosts via SSH keys and grouping them in an inventory file based on their role. You will run standard playbooks for base build tasks and customized playbooks based on server roles, utilizing GitLab for code updates when needed. You will also use Red Hat Satellite to manage repositories.
- Developer Toolset and Application Administration: Administer, install, and upgrade servers and the applications that software engineers need to use, specifically those that are part of the software development process. This involves being responsible for standing up and tearing down complete development, testing, and production environments, provisioning servers, configuring network settings, and deploying applications and services. Examples of these applications include GitLab, Subversion, Bitbucket, Confluence, Jira, and Smartbear.
- Linux System Migration: Lead the migration of our existing on-prem Linux servers and applications to a cloud platform (e.g., AWS, Azure, or GCP). This includes planning, execution, and validation to minimize downtime and ensure data integrity. While a few one-off physical servers use a hardened RHEL image, most of our environment is virtual/cloud.
- CI/CD Pipeline Management: Collaborate with development teams to build and maintain robust Continuous Integration/Continuous Deployment (CI/CD) pipelines. You'll work with tools like Jenkins, GitLab CI, or CircleCI to automate software build, test, and deployment processes. While the primary focus is on maintaining tools, helping with pipeline creation may be a secondary or tertiary responsibility.
- Monitoring & Troubleshooting: Implement and manage monitoring and logging solutions (e.g., Prometheus, Grafana, ELK stack) to proactively identify and resolve performance issues, system failures, and security vulnerabilities.
- Security & Compliance: Ensure our Linux systems and infrastructure are secure by implementing best practices, managing user access, and conducting regular audits.
