Sr Linux Administrator

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:

• Act as the primary escalation point for Linux issues across engineering, from routine to complex, and own first triage of incoming requests
• Troubleshoot the daily reality of a mixed fleet: authentication and access, services, storage and filesystems, performance, and remote connectivity
• Provision Linux hosts end-to-end against established procedures, from laptops and workstations to rack-mounted servers and lab systems
• Own access and authentication operations and recurring fleet maintenance — patching, health checks, backup verification, and capacity management
• Maintain the configuration management codebase with small, reviewed changes, freeing the senior engineering side of the team for architecture work. 

About You:

• 5+ years of hands-on Linux systems administration in production, owning fleet health rather than ticket-by-ticket task work
• Configuration management experience — reading, modifying, and debugging automation, not just running it — in an infrastructure-as-code model with peer review
• Medium-to-advanced troubleshooting across services, networking, storage, authentication, and performance, with the judgment to recognize when documentation runs out
• Enterprise directory services integration on Linux, credential and key management, and scripting proficiency
• Proven ability to be an escalation point for technical teams: triaging ambiguous reports and managing competing priorities without losing requests. 

Nice to haves but not required:  

You should still apply even if you don't have all of these! 

• Automated bare-metal and VM provisioning at scale, with image and template management
• Precision time synchronization for test and measurement systems
• Kernel and driver-level depth: module management, hardware troubleshooting, or performance tuning
• Containerization, CI/CD, observability, or hardening to a published security baseline
• Aerospace, manufacturing, or test operations environments
