Onsite DevOps Engineer; Linux Admin Focus

Overview

Join to apply for the Onsite Dev Ops Engineer (Linux Admin Focus) role at Object Computing, Inc.

This is a full-time, on-site position based in St. Louis County, Missouri. This role is for a highly skilled Dev Ops Engineer with a deep background in Linux systems administration, focusing on automating infrastructure, migrating on-prem Linux environments to the cloud, and building and maintaining development and production environments. A core focus is on standing up and maintaining the toolsets and applications used by software engineers in the software development process.

This position has no on-call or pager duty requirements.

• 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 Git Lab 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 standing up and tearing down complete development, testing, and production environments, provisioning servers, configuring network settings, and deploying applications and services. Examples 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). 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, Git Lab CI, or Circle
  
  CI 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

• Extensive Linux
  
  Experience:
  
  Minimum of 5 years of professional experience as a Linux Administrator or in a similar role. You should be an expert in the Linux command line, scripting (Bash, Python), and system-level troubleshooting. Experience with Red Hat Enterprise Linux and its associated activities, such as creating VM templates and managing OS-level infrastructure, is required
• 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, including playbook development and managing updates via Git Lab, is essential
• Cloud Computing:
  Practical experience with at least one major cloud provider (AWS, Azure, or GCP), including a solid understanding of compute, storage, networking, and database services. Experience managing virtual/cloud environments is crucial
• Developer Toolset…
