Teledyne Technologies Incorporated provides enabling technologies for industrial growth markets that require advanced technology and high reliability. These markets include aerospace and defense, factory automation, air and water quality environmental monitoring, electronics design and development, oceanographic research, deepwater oil and gas exploration and production, medical imaging and pharmaceutical research.
We are looking for individuals who thrive on making an impact and want the excitement of being on a team that wins.
Job Description
We are seeking a skilled Systems Administrator to join our dedicated infrastructure operations team in Huntsville, Alabama-the Rocket City. In this hands-on role, you'll focus on the day-to-day administration, maintenance, and support of our Red Hat OpenShift container platforms and Linux environments that underpin mission-critical applications for NASA's ongoing operations on the International Space Station (ISS) and the Artemis program, which is ushering in a new era of lunar exploration and preparing for human missions to Mars.
As we advance our infrastructure with container orchestration and robust automation, you'll handle platform troubleshooting, automate routine tasks, ensure system reliability, and provide direct support to users and teams. This position offers the chance to maintain high-availability systems in a high-stakes aerospace environment, directly contributing to NASA's historic space exploration efforts and working on technology that enables humanity's expansion into the solar system.
Key Responsibilities
  • Administer and maintain Red Hat OpenShift platforms, including daily operations such as cluster monitoring, user management, resource allocation, patching, upgrades, and troubleshooting platform issues to minimize downtime.
  • Perform advanced Linux (RHEL) system administration tasks, including installation, configuration, security hardening, performance tuning, backup/recovery, and log management.
  • Develop and execute automation scripts and playbooks using Ansible and Ansible Automation Platform to automate repetitive administrative tasks, configuration management, deployments, and system maintenance on OpenShift and Linux environments.
  • Support end users and application teams by resolving daily operational issues related to OpenShift and Linux systems, providing guidance, and ensuring smooth access and functionality.
  • Document system configurations, operational procedures, runbooks, and troubleshooting guides with clear, detailed written communication to facilitate team knowledge sharing and compliance.
  • Implement and support Infrastructure as Code (IaC) practices using tools like Terraform for consistent provisioning and configuration management.
  • Utilize GitOps workflows and tools such as GitLab for version-controlled infrastructure changes, collaborative deployments, and pipeline automation.
  • Monitor system performance and health, respond to alerts and incidents, conduct root cause analysis, and apply fixes to maintain reliability, security, and compliance in regulated environments.
  • Collaborate with developers, DevOps teams, and stakeholders to integrate OpenShift support with application deployments and resolve cross-team operational challenges.
  • Stay up-to-date with Red Hat technologies, Linux best practices, automation tools, and container administration trends to improve operational efficiency.

Qualifications
  • Bachelor's degree in Information Technology, Computer Science, or a related field (preferred); equivalent professional experience accepted.
  • 6+ years of hands-on experience in systems administration, with strong emphasis on Linux/Red Hat environments and container platforms.
  • Proven expertise in administering Red Hat OpenShift, including troubleshooting, cluster operations, and supporting production workloads.
  • Proficiency in Linux system administration (RHEL preferred) and scripting (e.g., Bash) for task automation.
  • Solid experience with Ansible and Ansible Automation Platform for configuration management and automation.
  • Working knowledge of Infrastructure as Code techniques and tools like Terraform.
  • Familiarity with GitOps practices and tools such as GitLab for version control and CI/CD workflows.
  • Strong written and verbal communication skills, with experience creating clear documentation, processes, and procedures.
  • Ability to work effectively with end users, developers, and cross-functional teams to address operational needs.
  • U.S. citizenship or eligibility to obtain required clearances for NASA/government-related projects (preferred).

Preferred Skills
  • Red Hat certifications (e.g., RHCSA, RHCE, OpenShift Administration) and/or AWS certifications.
  • Experience in aerospace, defense, government contracting, or mission-critical IT operations with focus on security and compliance standards.
  • Familiarity with monitoring tools (e.g., Prometheus/Grafana), logging solutions, and hybrid/on-premises environments.
  • Background in supporting containerized applications, DevOps practices, or cloud-adjacent technologies (AWS familiarity a plus, though primary focus is OpenShift).
  • Enthusiasm for space exploration and contributing to NASA's groundbreaking missions.

We offer competitive compensation, comprehensive benefits, ongoing training opportunities, and the privilege of supporting technology that powers humanity's journey to the Moon, Mars, and beyond. If you're a detail-oriented systems administrator passionate about keeping critical infrastructure running smoothly in an exciting aerospace context, apply today!
