About The Position

The Sr Linux Administrator serves as the primary escalation point for Linux issues across engineering, owning initial triage of incoming requests and troubleshooting a mixed Linux fleet. The role provisions Linux hosts end-to-end, including laptops, workstations, rack-mounted servers, and lab systems, and owns access and authentication operations as well as recurring fleet maintenance. Responsibilities also include maintaining the configuration management codebase through small, reviewed changes, allowing senior engineers to focus on architecture.

Requirements

• At least 5 years of hands-on Linux systems administration in production, owning fleet health rather than ticket-by-ticket task work.
• Configuration management experience, including reading, modifying, and debugging automation 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 serve as an escalation point for technical teams, triage ambiguous reports, and manage competing priorities without losing requests.

Nice To Haves

• 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, including module management, hardware troubleshooting, or performance tuning.
• Experience with containerization, CI/CD, observability, or hardening to a published security baseline.
• Experience in aerospace, manufacturing, or test operations environments.

Responsibilities

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

Benefits

• Competitive salary and equity.
• Generous PTO and sick leave policy.
• Parental leave.
• Annual learning and development stipend.
