Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The company is at a unique inflection point—early enough to shape product and culture, but far enough along that Terran R is tangible and gaining momentum. 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. In this Senior Systems Administrator role, you will strengthen the reliability, scalability, and performance of Relativity's critical infrastructure platforms in Long Beach, supporting Terran R manufacturing, test, and engineering operations. You'll take ownership of Linux systems administration—deploying, configuring, automating, and maintaining production systems across on-premises and cloud environments (Azure/GCP). You'll provide advanced support for Active Directory, DNS, DHCP, and Enterprise Backups, ensuring uptime, data protection, and compliance (AS9100). You'll partner closely with senior systems engineers (Linux, Windows, Infrastructure) to operationalize designs and ensure seamless handoff between system architecture and system administration. Additionally, you'll mentor junior administrators, building their technical depth and operational maturity, while standardizing and automating day-to-day administration tasks. You bring 6+ years of progressive Linux and Windows systems administration experience in enterprise or mission-critical environments. You have deep expertise in Linux systems administration, including configuration management, patching, and performance tuning. The IT team balances near-term execution with long-term vision, developing scalable solutions and processes to enable the company's growth. The evolving complexity of the IT environment offers opportunities to stretch and sharpen problem-solving and hands-on technical skills.
