Engineer – Electrical Design – Data Centre

Position

The Engineer – Electrical Design – Data Centre is a full-time role based in Singapore or Indonesia (Batam).

The role reports to the Senior Manager – Data Centre.

Overview

The Engineer – Electrical Design is responsible for the design, technical governance and engineering support of electrical infrastructure across the company’s data centre portfolio. The role supports the full asset lifecycle – from concept design and construction through commissioning, operations, upgrades and capacity expansion – to ensure facilities meet the highest standards of availability, reliability, scalability, sustainability and operational efficiency.

Working closely with internal design, construction, operations and commissioning teams, the Engineer – Electrical Design will develop and review electrical engineering solutions that support mission-critical environments while ensuring compliance with company design standards and industry best practices.

  • Lighting and emergency lighting systems.
• Perform electrical load calculations, short circuit studies, protection coordination, voltage drop analysis, arc flash assessments and equipment sizing.
• Evaluate emerging power technologies, including lithium-ion battery energy storage systems (BESS), renewable energy integration and grid-interactive solutions.
• Develop standardised electrical design guidelines and engineering specifications across the data centre portfolio.

Design Review & Technical Governance

• Review consultant and contractor designs to ensure compliance with company standards, project requirements and applicable codes.
• Participate in design reviews, constructability reviews, value engineering and technical risk assessments.
• Ensure electrical designs support maintainability, operational resilience, energy efficiency and future scalability.
• Manage technical deviations and engineering change requests.

Project Delivery

• Support project teams throughout design, procurement, construction, commissioning and handover.
• Review technical submissions, vendor proposals, equipment selections and shop drawings.
• Participate in Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), Integrated Systems Testing (IST) and commissioning activities.
• Resolve complex electrical engineering issues during project execution.

Operations & Asset Lifecycle Support

• Provide engineering support for operating data centres.
• Evaluate electrical system performance and recommend improvements to reliability, capacity and energy efficiency.
• Support root cause analysis (RCA) of electrical failures and develop corrective actions.
• Plan infrastructure upgrades, equipment replacement and capacity expansion while maintaining operational continuity.
• Collaborate with operations teams to optimise preventive maintenance strategies and improve asset reliability.

Sustainability & Innovation

• Support initiatives to improve Power Usage Effectiveness (PUE), energy efficiency and overall facility sustainability.
• Evaluate emerging electrical technologies, energy-efficient equipment, battery energy storage systems, renewable energy integration and digital engineering solutions.
• Promote standardisation, automation and continuous improvement across the electrical engineering function.

Qualifications & experience

• Bachelor’s Degree in Electrical Engineering or equivalent.
• Minimum 5 years of relevant experience in electrical design of mission-critical facilities, with significant exposure to hyperscale or enterprise data centres.
• Experience working for a data centre owner/operator, engineering consultancy or EPC contractor delivering large-scale mission-critical projects. Experience in the following matters would be a plus:
  • Utility interconnection and grid coordination.
  • High-voltage (66-230 kV) substations and transmission infrastructure.
  • Capacity planning for AI/HPC workloads (50-150+ MW campuses).
• Professional Engineer (PE), Chartered Engineer (CEng) or equivalent professional registration is preferred.

Key competencies

• Strong knowledge of mission-critical electrical power systems and resilient electrical infrastructure.
• Experience in the design of MV/LV power distribution systems, substations, UPS systems, standby generators and critical power architecture.
• Knowledge of data centre electrical topologies, including distributed redundant, block redundant and concurrently maintainable power systems.
• Understanding of electrical redundancy philosophies (N, N+1, 2N, 2N+1 and distributed redundancy).
• Familiarity with IEC standards, IEEE standards, NFPA 70 (NEC), NFPA 70E, IEC 60364, local electrical codes and utility requirements.
• Experience performing electrical system studies, including load flow, short circuit, protection coordination and arc flash analysis using software such as ETAP, SKM PowerTools or EasyPower.
• Proficiency in AutoCAD, Revit MEP, Navisworks and BIM coordination.
• Understanding of commissioning methodologies and integrated systems testing for mission-critical electrical systems.
• Familiarity with Building Management Systems (BMS), Electrical Power Monitoring Systems (EPMS), Supervisory Control and Data Acquisition (SCADA) systems and Data Centre Infrastructure Management (DCIM) platforms.
• Knowledge of power quality, harmonic mitigation, grounding systems and electrical safety practices.
• Understanding of renewable energy integration, battery energy storage systems (BESS) and energy management strategies is desirable.
