Job description

Lead Electrical Engineer - High Voltage (230 kV & Above)

Location: Singapore

Industry: Power Generation, Transmission & Distribution, Energy Infrastructure

Position: Lead Electrical Engineer

Specialisation: High Voltage Substations, Switchgear, Transformers & Electrical Infrastructure

Reporting To: Lead Electrical Engineer / Engineering Manager / Project Manager

Position Overview

We are seeking an experienced and technically proficient Senior Electrical Engineer to support the engineering, design coordination and execution of high-voltage electrical infrastructure projects in Singapore.

The successful candidate will be involved in the complete project lifecycle, from tendering, bidding and technical proposal preparation through detailed engineering, procurement support, construction supervision, testing, commissioning, energisation and final project handover.

The role requires strong technical knowledge and practical engineering experience in high-voltage electrical systems operating at 230 kV and above , including transmission substations, Gas Insulated Switchgear (GIS), Air Insulated Switchgear (AIS), power transformers, circuit breakers and associated electrical infrastructure.

The Senior Electrical Engineer will work closely with the Lead Electrical Engineer, Engineering Manager, clients, consultants, contractors and equipment manufacturers to ensure engineering activities are executed safely, efficiently and in accordance with approved designs, technical specifications, project schedules and applicable standards.

Candidates with hands‑on experience in high-voltage switchgear and transformer installation, testing and commissioning will be highly regarded. Previous experience in power plants, power generation facilities or large‑scale energy infrastructure projects will be advantageous.

Key Responsibilities

1. 1. Tendering, Bidding & Technical Proposal Support
   Support tendering and bidding activities for high-voltage electrical infrastructure and power engineering projects.
   Review tender documents, Invitations to Tender (ITT), employer requirements, technical specifications, drawings and scope of work.
   Assist in preparing electrical technical proposals, engineering methodologies, technical schedules and tender documentation.
   Review preliminary electrical designs, equipment specifications and engineering calculations to support tender submissions.
   Prepare and verify Bills of Quantities (BOQ), material take-offs and preliminary equipment requirements.
   Assist with technical cost estimation and engineering input for project budgets.
   Review vendor quotations, technical submissions and equipment specifications for compliance with tender requirements.
   Identify technical risks, engineering constraints, project interfaces and potential construction challenges.
   Participate in technical clarification meetings with clients, consultants, contractors and equipment suppliers.
   Support value engineering studies and recommend technically suitable and cost‑effective solutions.
   Coordinate with senior engineering, commercial and procurement teams to ensure timely completion of tender deliverables.
2. 2. High‑Voltage Electrical Engineering & Design
   Perform and coordinate electrical engineering activities for high‑voltage substations and electrical systems operating at 230 kV and above.
