About the Team: 

The IT team is responsible for the full scope of computing infrastructure, end-user systems, servers, virtualization, cloud, networking, software services, telecommunications, and information security. You'll support every function across the company, from the production floor to flight operations, enabling Relativity's world-class team to design, build, and launch rockets. The team balances near-term execution with long-term vision, developing scalable solutions and processes to enable the company's growth. The evolving complexity of our IT environment offers opportunities to stretch and sharpen problem solving and hands-on technical skills. We invest in our people, encouraging ownership, cross-training, and advancement, so our team can grow as fast and ambitiously as the company itself.

About the Role:

  • Strengthen the reliability, scalability, and performance of Relativity's critical infrastructure platforms in Long Beach, supporting Terran R manufacturing, test, and engineering operations
  • Take ownership of Linux systems administration-deploying, configuring, automating, and maintaining production systems across on-prem and cloud environments (Azure/GCP)
  • Provide advanced support for Active Directory, DNS, DHCP, and Enterprise Backups, ensuring uptime, data protection, and compliance (AS9100)
  • Partner closely with senior systems engineers (Linux, Windows, Infrastructure) to operationalize designs and ensure seamless handoff between system architecture and system administration
  • Mentor junior administrators, building their technical depth and operational maturity, while standardizing and automating day-to-day administration tasks

About You:

  • 6+ years of progressive Linux and Windows systems administration experience in enterprise or mission-critical environments
  • Deep expertise in Linux systems administration, including configuration management, patching, and performance tuning
  • Advanced understanding of Active Directory, DNS, DHCP, and enterprise backup solutions (e.g., Veeam, Commvault, Rubrik, etc.)
  • Solid grasp of networking fundamentals and experience troubleshooting at the network/system boundary
  • Proven ability to manage and monitor large environments with an emphasis on reliability, automation, and documentation
  • Strong analytical and problem-solving skills, with the ability to independently own issues through resolution

Nice to haves but not required:  

  • Experience with Azure, GCP, or hybrid-cloud systems administration
  • Exposure to configuration management and orchestration tools (Ansible, Puppet, Terraform, etc.)
  • Familiarity with enterprise backup compliance and retention policies
  • Scripting skills in Bash, Python, or PowerShell for automation and system health monitoring
