Sr. Data Center Technician

About the role

We are looking for an experienced Senior Onsite Data Center Professional to apply specialized technical expertise and advanced judgment in a fast-paced, complex AI/HPC environment. Rather than merely executing established procedures, this role demands independent analysis, complex problem-solving, and decisive action to address large-scale infrastructure challenges. You will take full ownership of technical solutions and strategic recommendations, serving as a primary authority for issue resolution rather than simply escalating problems. In this senior capacity, you will drive process optimizations, provide critical technical guidance to cross-functional teams, and actively shape operational strategies to support cloud-scale compute and storage environments. Adaptability, advanced technical judgment, and the ability to influence outcomes are central to your success in this role.

Location: Onsite in Columbus, Georgia at the customer’s data center. Candidates need to be within 45 minutes of the site to be eligible for consideration. Travel: None.

Responsibilities

• Advanced Diagnostics & Problem Solving: Exercise independent technical judgment to lead advanced hardware diagnostics, isolate root causes, and own the resolution of complex AI/HPC issues (e.g., GPU kernel hangs, interconnect anomalies) ensuring optimal cluster stability.
• Technical Authority & Ownership: Serve as the definitive technical authority and primary escalation point within the client ticketing system, taking full ownership of complex hardware and network challenges to develop solutions rather than merely escalating them.
• Continuous Process Improvement: Drive operational efficiencies by evaluating current workflows and implementing systemic process improvements. Lead the documentation and continuous refinement of operational strategies and Standard Operating Procedures (SOPs).
• Technical Guidance & Mentorship: Provide expert technical guidance, mentorship, and training to junior staff on complex ticket resolution, physical interventions, and safety protocols, heavily influencing team development and decisions.
• Risk Assessment & RCA: Identify risks, assess systemic impacts, and lead cross-functional Root Cause Analysis (RCA) investigations for recurrent hardware or facility failures, recommending and implementing corrective actions to prevent future outages.
• Cross-Functional Collaboration: Collaborate directly with infrastructure engineering teams to maintain overarching cluster health, apply specialized expertise to optimize node uptime, and guide the execution of strategic data center maintenance.
• Vendor Strategy & Management: Serve as the primary technical liaison with third-party vendors, using technical judgment to evaluate options, manage advanced RMA escalations, and ensure SLA compliance for hardware replacements.
• Advanced Network Remediation: Evaluate complex fabric topologies and remediate physical layer outages across HPC cluster networks, applying deep expertise in InfiniBand and high-bandwidth optical networks.
• Strategic Incident Response:
