Primary Design Engineer

We are a leading EPC contracting company in Saudi Arabia, specializing in

high voltage (HV) and extra-high voltage (EHV) substations , overhead transmission lines (OHTL), power plants, water treatment plants, water pipelines, and industrial plant projects. To support the successful execution of our substation projects, we are seeking an experienced

Primary Design Engineer

to develop and optimize the primary design of

HV / EHV substations . Position Overview : The

Primary Design Engineer

will be responsible for the

design and development of primary electrical systems

for substations, including

HV / EHV switchyards, power transformers, busbars, grounding systems, and overall layout planning . This role requires expertise in

substation design standards, layout optimization, and electrical equipment selection , ensuring compliance with

SEC, IEC, IEEE, and other international standards . Key Responsibilities : 1. Substation Primary Design & Engineering : Develop

conceptual, preliminary, and detailed primary designs

for

HV / EHV substations (132kV, 220kV, 400kV, and above) . Prepare

substation general arrangements, single-line diagrams (SLDs), and layout drawings . Design and optimize

busbar configurations, cable routing, earthing systems, and protection clearances . Select and specify

major substation equipment , including

power transformers, GIS / AIS switchgear, circuit breakers, disconnectors, and surge arresters . 2. Layout Planning & Optimization : Develop

substation layouts and sectional views

based on space constraints and functional requirements. Ensure adequate

clearance and accessibility

for operation and maintenance. Evaluate different

AIS (Air-Insulated Switchgear) and GIS (Gas-Insulated Switchgear) configurations

to determine optimal solutions. 3. Electrical System Studies & Analysis : Perform

short-circuit analysis, load flow studies, and insulation coordination studies . Ensure proper selection of

busbars, insulators, and supporting structures

based on mechanical and electrical stress calculations. Conduct

lightning protection and grounding system studies

to ensure compliance with safety regulations. 4. Compliance & Standardization : Ensure all designs comply with

SEC (Saudi Electricity Company), IEC, IEEE, NEC, and NESC

standards. Maintain

QA / QC procedures for design approvals

and internal design reviews. Coordinate with regulatory authorities for

design approvals and compliance assessments . 5. Coordination with Multidisciplinary Teams : Work closely with

secondary design engineers, protection engineers, and civil teams

to ensure seamless project execution. Coordinate with

procurement teams and vendors

to review technical offers for substation equipment. Provide support to project execution teams for

design clarifications and implementation guidance . 6. Substation Equipment Selection & Specification : Prepare

technical specifications for transformers, switchgear, and HV equipment . Evaluate vendor proposals and recommend

cost-effective and technically feasible solutions . Ensure substation components are compatible with

system voltage, fault levels, and environmental conditions . 7. Documentation & Reporting : Prepare and review

technical reports, design calculations, and drawings . Maintain a

design database for substation projects , including approved layouts and modifications. Provide

progress reports and presentations

to project managers and clients. 8. Site Support & Troubleshooting : Provide

technical assistance

during substation construction, installation, and commissioning. Address

design-related issues encountered in the field

and propose solutions. Conduct

site visits to validate the implementation of primary designs . Qualifications : Education : Bachelor’s degree in

Electrical Engineering or Power Systems Engineering . Master’s degree in

Power Engineering or High Voltage Systems

is an advantage. Experience : Minimum

8+ years

of experience in

substation primary design . Experience with

132kV, 220kV, or 400kV substation projects

is highly preferred. Key Skills : Expertise in

substation layout planning, busbar design, and HV equipment selection . Proficiency in

AutoCAD, ETAP, PLS-CADD, and other electrical design software . Strong knowledge of

SEC, IEC, IEEE, and ANSI standards . Excellent

problem-solving and analytical skills

for optimizing substation design. Ability to

collaborate with multidisciplinary teams

for seamless project execution. Preferred Certifications : SEC (Saudi Electricity Company) approval or certification

is an advantage. PMP or Chartered Engineer (CEng) certification

is a plus.
