Job description

At Relativity Space, we're building rockets to serve today's needs and tomorrow's breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that's just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we're writing together. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.

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

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.
Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.

Hiring Range:
$103,000—$155,000 USD

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
