• Approve SLDs, layout drawings, equipment specifications, and GA drawings for switchyard and control room infrastructure.
• Conduct and review power system studies such as load flow, short circuit, insulation coordination, earthing and lightning protection design.
• Review protection philosophy, relay coordination studies, CT/PT sizing, and control & protection logic diagrams.
• Guide civil/structural design of switchyard foundations, control rooms, and cable trenches in line with seismic, soil, and load conditions.
• Interface with OEMs for procurement and integration of HV equipment such as circuit breakers, isolators, CTs, VTs, LA, busbars, and switchgear.
• Ensure technical compliance with CEA, CERC, STU, DISCOM, CEIG regulations, and international codes (IS, IEC, IEEE, UL, NFPA).
• Support technical design inputs during pre-bid and EPC proposal stages including BOQ, layouts, and design briefs.
• Supervise detailed design documentation for submission to clients, consultants, and statutory bodies.
• Coordinate with SLDC/STU/CEIG for interconnection compliance, approvals, and energization procedures.
• Ensure compatibility and integration of protection, SCADA, and remote operation systems with client networks.
• Oversee FAT, SAT, and QA/QC compliance during design and implementation stages.
• Conduct root cause analysis of system issues and recommend corrective/preventive actions.
• Maintain and enforce internal engineering standards, templates, and best practices documentation.
• Mentor junior engineers and enable continuous skill development within the team.
• Analyze system performance, conduct root cause analysis for failures, and support predictive maintenance.
• Prepare technical reports, test plans, compliance checklists, and risk assessments (DFMEA).
• Participate in safety reviews, technical case studies, and client discussions.
• Support technical inputs for RfPs, DPRs, feasibility reports, and lender due diligence.

Qualifications & Experience:

• Bachelors or Masters degree in Electrical Engineering.
• 5–12 years of hands-on experience in high-voltage substation design and grid interfacing (11kV to 220 kV).
• Experience delivering substations for transmission utilities, IPPs, renewable energy developers, or large industrial clients.
• Proficient in design software/tools such as AutoCAD, ETAP, CYME, Dig SILENT, PSCAD, and Excel-based sizing calculators.
• Deep understanding of HV equipment ratings, layouts, statutory approvals, and utility coordination.
• Familiarity with SCADA, RTU, communication protocols (IEC 61850, Modbus), and substation automation systems.
• Experience working with utilities like PGCIL, GETCO, TANGEDCO, or in renewable energy evacuation is desirable.
• Experience managing design teams of 4–15 engineers and coordinating with external consultants and clients.

Desirable Attributes:

• Strong technical leadership with a delivery mindset.
• Ability to guide and manage a cross-functional design team.
• Good communication and client coordination skills.
• Detail-oriented with a structured and process-driven approach.
