Core Responsibilities

Primary Functions

Manage daily data center operations including rack-and-stack of servers, storage arrays, switches, and telecommunications gear, ensuring proper cable management, labeling, and installation to vendor and organizational standards.
Perform hands-on installation, configuration, and decommissioning of physical infrastructure (servers, network equipment, PDUs, UPS modules) and verify power/circuits, grounding, and rack cooling readiness prior to commissioning equipment.
Execute and validate structured cabling work (Category 6/6A/7, single-mode/multi-mode fiber, MPO/MTP assemblies) and coordinate fiber testing (OTDR, power meter) and copper certification to guarantee link quality and SLAs.
Monitor and manage critical power infrastructure: UPS systems, static transfer switches, backup generators, automatic transfer switches (ATS), and PDUs; conduct regular battery and load testing and escalate anomalies.
Maintain environmental controls and HVAC oversight: verify CRAC/CRAH operation, chilled water systems, hot/cold aisle containment, temperature and humidity parameters, and environmental sensors to prevent thermal incidents.
Use DCIM (Data Center Infrastructure Management) tools and BMS (Building Management Systems) to maintain accurate asset inventory, track capacity utilization (power/cooling/rack space), and plan expansions proactively.
Respond to data center incidents and outages (power, cooling, network, hardware faults) with rapid triage, root cause analysis, and remediation, participating in incident postmortems and corrective action plans.
Perform firmware and hardware maintenance tasks (server BIOS, RAID controllers, network OS updates) following change control procedures to minimize downtime and maintain secure configurations.
Manage patch panels, cross-connects, and demarcation points; document and maintain wiring schematics, rack elevations, port mappings, and circuit diagrams in asset and configuration management systems.
Conduct scheduled preventive maintenance and lifecycle management for data center assets, including vendor-scheduled maintenance windows, spare parts inventory management, and hardware refresh coordination.
Implement and enforce physical security controls: access badges, biometric systems, CCTV monitoring, escort policies, and visitor logs to maintain compliance with corporate and regulatory requirements.
Operate ticketing and change management systems (ServiceNow, Jira) to log work orders, track maintenance, coordinate approvals, and provide timely status updates to stakeholders.
Perform capacity planning and forecasting for power, cooling, and space; develop recommendations and run capacity models to support procurement and architecture decisions.
Coordinate with vendors, integrators, and carriers for equipment deliveries, on-site vendor work, swap-outs, and service-level escalations; manage vendor safety and site access compliance.
Maintain detailed operational documentation — SOPs, runbooks, wiring diagrams, emergency procedures, and escalation matrices — to support consistent on-call and shift handovers.
Execute remote hands and boots-on-the-ground tasks for cloud providers, colocation customers, and internal stakeholders, ensuring secure handling of customer equipment and data.
Support backup and disaster recovery operations including tape rotation, removable media handling, off-site movement, and on-site testing of restores per DR playbooks.
Implement and monitor environmental and infrastructure alarms, thresholds, and automated actions (load shedding, PDU switching) to prevent cascading failures.
Ensure compliance with health, safety, and electrical codes (NFPA, OSHA) during installation, maintenance, and vendor activities and document risk assessments for high-voltage or critical work.
Troubleshoot complex electrical, mechanical, and network issues using multimeters, power analyzers, cable certifiers, and network diagnostic tools; escalate to engineering teams when required.
Participate in change advisory board (CAB) meetings and ensure all hardware and firmware changes meet rollback and test criteria to minimize production risk.
Validate network connectivity, VLAN and IP assignments, and handoff network ports to network engineering teams; test end-to-end connectivity and throughput where required.
Assist with asset lifecycle management including tagging, serial number capture, decommissioning wipe/destroy processes, and reconciliation against asset management systems.
Drive continuous improvement initiatives: automate repetitive tasks (scripting for inventory checks, DCIM reports), optimize workflows, and propose infrastructure improvements that increase reliability and reduce operating costs.
Provide on-call coverage and follow rotational duty schedules to ensure 24/7 availability of data center support, including emergency response and after-hours maintenance coordination.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Mentor junior technicians and provide training on safety procedures, rack standards, and cabling best practices.
Participate in audit preparation for compliance frameworks (SOC, ISO, PCI-DSS), supplying documentation and operational evidence for data center controls.
Assist in vendor procurement review and cost analysis for parts, repair services, and long-term maintenance contracts.
