• Coordinate with facilities for cooling, power budgeting, and physical security requirements.

• Perform routine datacenter health checks, environmental monitoring, and audits.

• Provide remote‑hands support for global sites as required.

Systems & Infrastructure Support

• Provision bare‑metal hosts and integrate hardware into virtualization or orchestration platforms.

• Collaborate with SRE, cloud, networking, and platform teams to support high‑availability workloads.

• Troubleshoot hardware and OS-level issues (Linux/Windows) during physical interventions.

Documentation & Process

• Maintain rack elevation diagrams, cabling maps, and hardware configuration records.

• Develop and maintain SOPs for installation, decommissioning, maintenance, and emergency recovery.

• Drive improvements in reliability, performance, physical infrastructure efficiency, and operational standards.

• Expert‑level experience with Cisco networking technologies (CCNP or higher preferred).

• Proven experience with AWS networking and cloud‑native networking architectures.

• Strong hands‑on experience with racking/stacking servers, cabling, hardware diagnostics, and physical maintenance.

• Knowledge of enterprise server platforms (Cisco, Dell, HPE, Supermicro).

• Familiarity with Linux or Windows for basic troubleshooting.

• Strong understanding of networking fundamentals (VLANs, LACP, routing, switching).

• Ability to lift \~50 lbs and work in hot/cold aisle environments.

Preferred Qualifications

• Experience with virtualization platforms (VMware, Proxmox, KVM) or bare‑metal orchestration tools (MAAS, Tinkerbell).

• Experience with hardware monitoring, observability, or datacenter telemetry systems.

• Knowledge of datacenter best practices including power planning, cooling optimization, and structured cable management.

Soft Skills

• Strong interpersonal skills and ability to collaborate effectively within cross‑functional teams.

• Excellent written and verbal communication skills.

• Meticulous attention to detail in documentation, configuration, and operational processes.

• Strong problem‑solving and root‑cause analysis skills.

• Ability to manage multiple priorities and work independently.
