Onsite DevOps Engineer; Linux Admin Focus

We are seeking a highly skilled Dev Ops Engineer with a deep background in Linux systems administration. This role is a perfect fit for a seasoned sysadmin who is ready to transition into or expand their expertise in a Dev Ops methodology. You will be crucial in automating our infrastructure, migrating our on-prem Linux environments to the cloud, and building and maintaining development and production environments.

A core focus of this role is on standing up and maintaining the specific toolsets and applications used by software engineers in the software development process. This is a full-time, on-site position based in St. Louis County, Missouri. This position has no on-call or pager duty requirements.

• Infrastructure Management & Automation:
  Design, implement, and maintain scalable and secure Linux-based infrastructure using IaC tools like Terraform or Ansible. Automate repetitive tasks, manage configuration, and ensure 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 name servers. After VM deployment, 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. Run standard playbooks for base build tasks and customized playbooks based on server roles, utilizing Git Lab for code updates when needed. 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. 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 Git Lab, Subversion, Bitbucket, Confluence, Jira, and Smartbear.
• Linux System Migration:
  Lead the migration of existing on-prem Linux servers and applications to a cloud platform (e.g., AWS, Azure, or GCP). Plan, execute, and validate to minimize downtime and ensure data integrity. Most of the environment is virtual/cloud with a few one-off physical servers using a hardened RHEL image.
• CI/CD Pipeline Management:
  Collaborate with development teams to build and maintain robust Continuous Integration/Continuous Deployment pipelines. Work with tools like Jenkins, Git Lab CI, or CircleCI to automate software build, test, and deployment processes. Primary focus is on maintaining tools; pipeline creation assistance may be secondary.
• 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 Linux systems and infrastructure are secure by implementing best practices, managing user access, and conducting regular audits.

• Extensive Linux
  
  Experience:
  
  Minimum 5 years as a Linux Administrator or similar. Expert in Linux command line, scripting (Bash, Python), and system-level troubleshooting. Experience with RHEL and related activities such as creating VM templates and managing OS-level infrastructure.
• Dev Ops Tooling:
  Hands‑on experience with key Dev Ops tools, including version control systems (Git), IaC tools such as Ansible and Terraform, and CI/CD platforms. Proficiency with Ansible for server configuration and management, playbook development, and managing updates via Git Lab.
• Cloud Computing:
  Practical experience with at least one major cloud provider (AWS, Azure, or GCP), including compute, storage, networking, and database services. Experience managing virtual/cloud environments is crucial.
• Developer Toolset Maintenance:
  Proven experience installing, upgrading, and administering specific software development tools and applications such as Git Lab, Confluence, Jira, Subversion, Bitbucket, or Smartbear.
• Automation
  
  Skills:
  
  Proven ability to automate complex tasks and workflows. Passion for eliminating manual work and improving efficiency.
• Networking:
  Strong understanding of TCP/IP, DNS, DHCP, and firewalls.
• Communication:
  Excellent communication and collaboration skills to work effectively with development, QA, and operations teams.
• On‑site Availability:
  This is an on‑site position requiring presence in the St. Louis Office.

• Experience with containerization technologies like Docker and orchestration platforms like Kubernetes.
• Knowledge of scripting languages beyond Bash, such as Python or Ruby.
• Familiarity with container security best practices.
• Experience with configuration management tools like Ansible, Chef, or Puppet.
