Senior Electrical Design Engineer

Key Responsibilities • Lead the design development of electrical building services systems, including HV/LV power distribution, substations, transformers, standby generation, switchgear, cable containment/routing, lighting, small power, earthing, and lightning protection. • Prepare and review electrical design calculations, load schedules, single-line diagrams (SLDs), cable sizing, protection coordination/discrimination studies, and voltage drop calculations. • Produce and check design drawings and specifications using AutoCAD/Revit MEP (BIM), ensuring compliance with SS 638 (Code of Practice for Electrical Installations), SS 531, Singapore Standards, BCA, EMA, SCDF, and other relevant statutory and regulatory requirements. • Coordinate with architects, C&S engineers, mechanical/ACMV engineers, and other M&E disciplines to ensure clash-free, buildable, and coordinated designs. • Review and respond to tender and contract drawings, specifications, and Bills of Quantities for electrical scope; support tendering and cost estimation as needed. • Liaise with authorities (e.g. SP PowerGrid/EMA, SCDF, BCA) for submissions, approvals, and licensing of electrical installations. • Provide technical support during construction, including reviewing shop drawings, method statements, and material submissions from subcontractors/vendors. • Conduct site inspections, testing, and commissioning oversight to ensure installed works conform to design intent and applicable codes. • Investigate and resolve technical issues arising on site, proposing practical and cost-effective design solutions. • Mentor and guide junior/graduate electrical engineers and draughtsmen, reviewing their output for technical accuracy. • Keep up to date with new technologies, energy-efficient design practices, and evolving regulatory requirements (e.g. Green Mark, sustainability standards). • Support project handover documentation, including as-built drawings, O&M manuals, and testing/commissioning records. Requirements Education • Degree in Electrical Engineering or related discipline; Professional Engineer (PE) registration in Singapore is an advantage. Experience • Minimum 6–10 years of relevant experience in electrical building services design, with at least 2–3 years in a senior/lead design role. • Proven track record on major building, infrastructure, or MRT/rail-related projects in Singapore is highly preferred. • Experience working with LTA, BCA, EMA, and SCDF submission processes. Skills & Competencies • Strong technical knowledge of electrical distribution systems, HV/LV switchgear, protection systems, standby power (generators/UPS), and lighting design. • Proficient in AutoCAD; working knowledge of Revit MEP/BIM workflows is highly advantageous. • Familiar with relevant Singapore Standards (SS 638, SS CP5, SS 531) and international standards (IEC/BS) as applicable. • Strong analytical, problem-solving, and design-coordination skills. • Good written and verbal communication skills; able to liaise confidently with consultants, authorities, and clients. • Leadership ability to guide a design team and manage multiple concurrent project deliverables. • Detail-oriented, organised, and able to work to project deadlines.
