Job Summary: 

We are looking for a skilled and motivated Electrical Design Engineer with a minimum of 3 years of 

experience to join our team. The ideal candidate will have a strong foundation in LV electrical design, 

power distribution, and extensive experience in designing for hazardous areas in compliance with 

NFPA 70 (NEC) and IEC 60079. 

This position involves preparing detailed electrical drawings, sizing and selecting electrical 

components, and ensuring design compliance with both functional and safety requirements for 

hydrogen facilities. 

Key Responsibilities: 

• Design and selection of MV/LV transformer, distribution panels, motor control panels and 

protection systems for industrial hydrogen applications. 

• Perform LV cable sizing and selection considering load analysis, voltage drop, ambient 

conditions, and derating factors. 

• Develop cable tray routing layouts, ensuring proper separation, support, and access in line 

with best practices and codes. 

• Design complete grounding systems, including grounding layout drawings (safety and 

instrument grounding), calculations, earthing pits, and bonding strategies according to local 

standards. 

• Develop and implement lightning protection systems, including layout drawings and material 

specifications per IEC 62305. 

• Design area lighting systems for hazardous and non-hazardous zones, including fixture 

selection, placement, and illumination levels. 

• Prepare service receptacle layouts and detailed drawings for utility and auxiliary power points 

across the site. 

• Generate comprehensive power distribution diagrams (SLDs, wiring schematics) for LV 

networks. 

• Prepare Bill of Materials (BOM) and perform detailed component selection for transformers, 

cables, trays, distribution boards, grounding systems, lighting, receptacles, and protective 

devices. 

• Ensure all electrical designs comply with: 

o NFPA 70 (NEC) – for US-based or NFPA-compliant projects 

• o IEC 60079 – for hazardous area classification, equipment protection, and zoning 

Other relevant international and local codes (IEC, SEC, etc.) 

• Select and specify Ex-rated equipment (Ex d, Ex e, Ex n, Ex i, etc.) suitable for the identified 

hazardous zones. 

• Coordinate with instrumentation, process, and mechanical teams to ensure proper inter-

discipline integration. 

• Support technical documentation, vendor evaluations, and procurement processes. 

Required Qualifications & Skills: 

• Bachelor’s Degree in Electrical Engineering or equivalent from an accredited university. 

• Minimum 3 years of experience in industrial electrical design and engineering. 

• Strong understanding of: 

o MV/LV transformer specification and protection 

o Cable sizing and power distribution 

o Cable tray design and routing 

o Grounding and lightning protection systems 

o Area and task lighting design 

• Solid experience in: 

o Hazardous area classification and compliance with NFPA 70 (NEC Article 500-516) and 

IEC 60079 series 

o Selection of Ex-certified electrical equipment 

• Proficiency in design tools such as AutoCAD 2D, AutoCAD Electrical, ETAP and Excel-based 

calculators 

• Knowledge of electrical safety, equipment spacing, clearances, and maintenance 

considerations in explosive environments. 

• Experience in preparing detailed construction drawings, BOMs, data sheets, and technical 

reports. 

• Excellent communication and coordination skills. 

Preferred Qualifications: 

• Experience in Hydrogen Refueling Station projects or similar explosive/hazardous 

environment facilities (e.g., oil & gas, chemical plants). 

• Familiarity with HAZOP, HAZID, or similar safety review processes. 

• Understanding of equipment zoning, IP/temperature class ratings 

• Familiarity with GCC regulations and local authority requirements (e.g., SEC, ARAMCO, 

ADNOC). 

• Familiar with Rivet software.
