Description

You will support a high-priority team as a senior System Administrator and technical contributor responsible for sustaining and evolving a high-performance operational IT environment. This is not a ticket-only administrator role — we're looking for someone who takes ownership of systems, documents with precision, builds strong relationships, and actively looks for ways to improve how engineers work every day.

This role requires a forward-leaning professional who enjoys working directly with users, optimizing workflows, and building repeatable processes that make future efforts faster and more efficient.

Responsibilities

• Install, configure, and maintain high-performance compute hardware, including NVIDIA H100, H200, and B300 class accelerator platforms.

• Uninstall and relocate existing equipment to a secure data warehouse while ensuring configuration integrity and proper tracking.

• Lead installation and sustainment efforts for new and legacy hardware within the warehouse environment.

• Document installation procedures, configurations, and lessons learned to create repeatable, scalable deployment playbooks.

• Develop strong working relationships with onsite System Administrators at the warehouse to streamline troubleshooting and escalate priorities when timelines require it.

• Identify gaps in onsite support coverage and recommend improvements to reduce downtime and response time.

• Partner directly with contract engineering teams to optimize system performance and user workflows.

• Maintain detailed technical documentation, diagrams, and standard operating procedures with a level of clarity that allows another engineer to step in seamlessly.

• Support virtualization efforts and contribute to long-term IT modernization strategies.

• Adapt as project requirements evolve, including future support for AWS, cloud integrations, and Large Language Model infrastructure.

Skills Requirements

• Strong Linux systems administration experience in operational environments.

• Experience installing and maintaining GPU-accelerated or high-performance compute systems, particularly NVIDIA enterprise-class hardware.

• Demonstrated ability to document technical processes clearly and professionally.

• Experience working within structured data center or warehouse environments.

• Familiarity with virtualization technologies and hypervisors.

• Ability to troubleshoot hardware and software issues across networked systems.

• Strong communication skills and experience interacting directly with users.

• Proven ability to operate independently while coordinating effectively with distributed support teams.

Nice to Haves

• Forward-leaning mindset with enthusiasm for improving user experience.

• Comfort working hands-on with hardware in a warehouse environment.

• Relationship builder who understands that success depends on strong coordination with onsite support teams.

• Flexible and growth-oriented, with interest in expanding into cloud, AWS, and LLM support over time.

• Commitment to building documentation and processes that make tomorrow's installs faster than today's.
