Substations - Design Engineer

About the role
Nexus Analytica is seeking a Design Engineer - Substations to support the engineering and delivery of HV/MV substations for giga-scale utility projects. This role is responsible for developing and reviewing substation designs that ensure safe, reliable, and standards-compliant integration of large-scale renewable generation into transmission and distribution networks.

The ideal candidate brings strong experience in substation primary design, solid understanding of secondary interfaces, and the ability to work across multidisciplinary teams in fast-paced EPC or developer environments.

Key Responsibilities

• Prepare and review engineering deliverables for HV/MV substations associated with large-scale solar PV plants, including single line diagrams, general arrangement layouts, sections, elevations, grounding drawings, and lightning protection layouts.
• Perform and check key electrical design calculations, including grounding/earthing studies, lightning protection, cable sizing, voltage drop, short-circuit calculations, auxiliary load calculations, and equipment sizing.
• Prepare and review technical specifications, equipment datasheets, BOQs, and material requisitions for substation systems.
• Support the design and selection of major substation equipment such as power transformers, GIS/AIS switchgear, circuit breakers, disconnectors, CTs, VTs, surge arresters, harmonic filters, shunt reactors/capacitor banks, and reactive power compensation equipment.
• Review vendor drawings, calculations, and technical submittals to ensure compliance with project requirements, grid code obligations, utility standards, and applicable international standards.
• Coordinate closely with solar plant design, grid interconnection, civil, structural, mechanical, protection, control, SCADA, and construction teams to ensure smooth interface management and integrated design delivery.
• Ensure designs comply with IEC, IEEE, ANSI, utility requirements, local regulations, and client specifications.
• Support project execution through design reviews, technical meetings, procurement support, site queries, construction clarifications, factory acceptance support, and commissioning assistance.
• Review or support secondary engineering deliverables such as control schematics, cable schedules, interconnection diagrams, panel layouts, and interface drawings to ensure full alignment between primary and secondary systems.
• Contribute to the standardization of substation design approaches across multiple giga-scale PV projects to improve quality, constructability, repeatability, and delivery efficiency.

Required Qualifications

• Bachelor's degree in Electrical Engineering.
• 4-8 years of experience in substation design engineering.
• Proven experience in HV/MV substation projects within utility, renewable energy, EPC, industrial, or consulting environments.
• Strong understanding of substation primary systems, equipment selection, and engineering interfaces.
• Experience supporting substations for utility-scale solar PV, renewable interconnection, or power infrastructure projects is strongly preferred.
• Familiarity with grid interconnection requirements and utility coordination for large renewable projects is an advantage.
• Good working knowledge of relevant standards including IEC, IEEE, ANSI, and utility-specific requirements.
• Strong coordination, communication, and technical review skills.

Preferred Profile

• Experience working on multiple substations across large renewable portfolios.
• Exposure to reactive power compensation, collector substations, and transmission interconnection design.
• Ability to work in multidisciplinary teams and manage parallel deliverables across fast-track projects.
• Detail-oriented, practical, and focused on delivering high-quality designs that are both technically robust and constructible.
