Job Description

PURPOSE OF THE ROLE

Responsible for ensuring the reliability, performance, safety, and compliance of all low-voltage electrical systems across Teraco's national data-centre estate. The role provides technical leadership, analytical insight, and hands-on operational support to maintenance teams, site operations, and service providers, with a strong focus on risk reduction, data-driven decision-making, and continuous improvement.



The position bridges engineering, operations, maintenance, and training, supporting the evolution from time-based preventative maintenance toward condition-based and insight-led electrical asset management, while maintaining strict compliance with SANS standards, OEM requirements, and Teraco engineering principles.

MAIN FUNCTIONS OF THE JOB

Oversight of Maintenance


Support the maintenance team in optimising national LV maintenance schedules to improve reliability, efficiency, and operational consistency. Analyse maintenance data with the maintenance team to identify systemic risks, recurring failures, efficiency improvement opportunities, and required corrective actions, ensuring follow-through and implementation. Participate in all major LV electrical maintenance activities to ensure appropriate scope and quality of work and coordinate with the GMR2.1 during MV maintenance interventions. Work with the Teraco maintenance department to advance the shift from preventative maintenance toward condition-based maintenance, leveraging data, monitoring, and system insights. Provide technical guidance to the Teraco maintenance department to ensure all electrical systems are maintained and tested in compliance with Teraco standards, international best practice, and OEM specifications
Load & Risk Management


Review load trends across all LV networks to identify early-warning indicators of: + Overloaded LV supply networks
+ Capacity constraints on UPS systems, STS units, and rectifiers
+ Areas of concern, including abnormal losses or inefficiencies
Support live-system load balancing, including UPS phase balancing, EC load verification, data validation, metering strategy alignment, and investigation of elevated neutral currents. Collaborate with site management and BMS teams to drive energy-efficiency improvements and optimise power quality across LV systems. Conduct detailed power quality analyses, including power factor, harmonic distortion, voltage dips/swells, and load imbalance evaluations.
Training, Mentorship & Knowledge Transfer


Provide targeted training to site technicians on LV best practices (balancing, trip testing, fault finding, PF management), and work with the L&D Manager to design and deliver programmes that enhance electrical competency across the organisation. Develop operational guidelines, engineering notes, and technical references to support consistent and safe LV operations. Create, review, and refine LV electrical system simulation scenarios, ensuring all teams regularly complete emergency-response exercises and remain proficient in required response protocols.
LV Infrastructure Performance & Compliance


Serve as the LV subject-matter expert in root-cause analyses relating to LV incidents, equipment trips, power quality disturbances, or component degradation; ensure corrective actions are tracked and national lessons learned are incorporated into scenario-based training. Ensure all LV assets comply with SANS standards and internal engineering requirements, providing guidance to maintain compliance across all sites. Perform regular LV equipment inspections to proactively identify and mitigate emerging issues. Review the availability and validity of CoCs in collaboration with the operations document controller, design team, and site management to ensure documentation accuracy and compliance.
Provide Technical Support to Operations


Close the skills gap between service providers and Teraco Operations by critically evaluating service-provider recommendations, validating proposed repairs, and supporting technicians with complex fault investigations. Deliver specialist LV engineering support to all regional operations teams, ensuring consistent technical guidance across the national estate. Act as an expert user of Teraco's Building Management Systems (including EBO and PME) to ensure maximum operational insight and value. Trend and analyse key operational parameters, including energy use, breaker operations, power factor, Total Harmonic Distortion, efficiency metrics, load imbalance, UPS losses, and alarm patterns. Collaborate with BMS teams and site management to develop meaningful dashboards and reporting tools that highlight performance trends and identify improvement opportunities for each facility.
