Job Summary

We are seeking a highly skilled Lead Engineer specializing in Extra High Voltage (EHV) Substation systems to support the design, engineering, and execution of hyperscale data center projects. The role involves end-to-end leadership of EHV/ HV infrastructure, ensuring reliability, compliance, safety, and timely delivery of power systems supporting large-scale mission-critical facilities.

Key Responsibilities

EHV / HV Substation Engineering

• Lead design, engineering, and review of

  EHV/HV substations (132kV/220kV/400kV)

  for hyperscale data center projects.
• Prepare and validate single-line diagrams (SLDs), protection schemes, short circuit studies, load flow, relay coordination, and grounding systems.
  
• Evaluate transformer specifications, switchgear, GIS/AIS systems, busbars, UPS interfaces, and overall electrical architecture.
  
• Oversee cable selection, routing, sizing, and termination strategies for high-voltage networks.
  

Project Planning & Execution

• Work closely with utility providers, DISCOMs, OEMs, EPC vendors, and contractors to ensure alignment of EHV infrastructure with project requirements.
  
• Review vendor drawings, technical submittals, FAT/SAT reports, and ensure adherence to design standards.
  
• Support site execution, installation, commissioning, and integration of EHV/HV systems.
  
• Ensure that substations meet hyperscale data center availability and redundancy standards (N+1, N+N).
  

Compliance & Standards

• Ensure designs comply with national/international standards (IS/IEC/IEEE/NFPA).
  
• Support internal audits, safety inspections, and energy compliance requirements.
  
• Drive risk assessments, reliability studies, and contingency power planning.
  

Cross-Functional Collaboration

• Work closely with data center design, MEP, operations, and capacity planning teams.
  
• Interact with cloud/hyperscale clients for technical discussions and design reviews.
  
• Coordinate with civil/structural teams for substation layouts, cable trenches, and equipment foundations.
  

Required Skills & Experience

• 10+ years of experience in

  EHV Substation Engineering

  , preferably with exposure to hyperscale data center, utilities, or mission-critical infrastructure.
• Strong experience with

  132kV/220kV/400kV

  substations, GIS/AIS systems, protection relays, and power distribution systems.
• Proficiency in tools like

  ETAP, DIgSILENT PowerFactory

  , AutoCAD, and relay configuration systems.
• Strong understanding of power system studies: short circuit, load flow, relay coordination, grounding, harmonic analysis.
  
• Prior experience handling EHV projects from concept design to commissioning.
  
• Good understanding of redundancy concepts (Tier III / Tier IV).
  
• Excellent stakeholder management, vendor coordination, and documentation skills.
  

Good-to-Have Skills

• Experience in data center electrical design (MEP integration).
  
• Exposure to UPS, DG systems, SCADA, BMS/EPMS integrations.
  
• Understanding of hyperscale client design standards (AWS, Azure, Google, Meta).
  
• PMP, CEA certification is a plus.
  

Education

• Bachelor’s degree in Electrical Engineering (B.E / B.Tech).
  
• Master’s degree in Power Systems / High Voltage Engineering preferred.
