⚡ Lead protection engineering across complex, mission-critical AC/DC electrical infrastructure in Singapore.

If you’re strong in ETAP, PSCAD, Siemens SIPROTEC 5 and SEL protection relays , this is a technically heavyweight role covering protection studies, relay configuration, design assurance and delivery.

About the role

You’ll provide senior electrical protection engineering expertise across the full project lifecycle — from modelling and protection studies through design review, testing support, defect closure and standards improvement.

The environment covers large-scale electrical infrastructure including switchgear, transformers, energy storage, microgrids and mission-critical facilities .

Key responsibilities

• Develop power-system models and protection studies using ETAP and PSCAD .
• Configure, programme and test Siemens SIPROTEC 5 protection relays using DIGSI 5 .
• Configure and integrate SEL protection relays , including associated RTAC equipment such as SEL-3530/3505.
• Develop and maintain SCD files .
• Complete grounding calculations, CT/VT sizing, voltage-drop calculations and associated electrical studies.
• Review contractor drawings and technical designs for protection, coordination and engineering quality.
• Identify technical, programme and cost risks and provide clear engineering direction.
• Drive improvements across system reliability, efficiency, cost and operational performance.
• Support defect rectification, punch-list closure and final electrical inspections.
• Act as the senior protection engineering interface between the client, consultants, contractors and equipment vendors.
• Maintain engineering standards, specifications, programming documentation and design records.

Requirements

• Strong electrical protection engineering background on complex power infrastructure.
• Hands-on experience with ETAP and PSCAD .
• Practical experience with SIPROTEC 5 / DIGSI 5 and SEL protection relays .
• Good working knowledge of relevant IEC and ANSI/NEMA standards .

Desirable / nice-to-have background

Experience across any combination of:

• Mission-critical or high-availability facilities.
• Switchgear and transformer systems.
• Battery energy storage systems.
• Microgrids.
• Large-scale AC and DC electrical infrastructure.
• IEC 61850 environments and SCD-file management.
• Protection design assurance, testing or commissioning.
• Client-side, consultancy, EPC or OEM environments.

Environment

This is a senior, technically demanding position where you’ll be expected to challenge protection designs, resolve complex engineering issues and give clear direction to delivery partners .

Experience working across consultants, EPCs, OEMs, contractors and client-side engineering teams would translate particularly well.

Strong profiles may currently be working as a Protection Lead, Senior Protection Engineer, Principal Protection Engineer, Power Systems Protection Engineer, Electrical Protection Engineer or Lead Protection Engineer .

Relevant backgrounds could include mission-critical infrastructure, utilities, substations, power generation, industrial power, data-centre infrastructure, electrical OEMs, EPCs or specialist power-system consultancies .

Particularly relevant environments include Siemens, SEL, switchgear/transformer manufacturers, protection specialists and major electrical engineering consultancies .
