Key Objectives

• Deliver accurate and timely designs for ground-mounted Solar PV projects.


• Optimize plant layout, electrical design, equipment selection, and overall system configuration.


• Minimize design errors, rework, and execution-related technical issues.

Candidate’s Profile

• Qualification: Bachelor’s degree in Electrical, Civil, Mechanical, or Renewable Energy Engineering; a relevant postgraduate qualification is an advantage.


• Position: Manager – Design/Engineering (Solar)


• Experience: 8+ years of relevant Solar PV Design & Engineering experience


• Compensation: 15LPA – 18LPA


• Location- Kolkata


• Demonstrated experience managing the design of ground-mounted solar projects totaling more than 100 MWp.


• Strong working knowledge of both civil and electrical aspects of utility-scale solar plants.


• Proven experience producing and reviewing engineering drawings, SLDs, BOMs, BOQs, cost estimates, and scopes of work.


• Experience coordinating clients, consultants, vendors, procurement, and site execution teams.


• Familiarity with relevant design software and tools, such as AutoCAD and PV system modelling or electrical analysis software; experience with civil design tools is an advantage.

Competencies & Skills

• Strong technical judgement across civil and electrical disciplines.


• Project leadership, planning, and coordination skills.


• Clear communication and effective stakeholder management.


• Attention to detail, sound problem-solving, and a cost-conscious approach.


• Ability to manage multiple projects and deliverables from design through execution.

Key Responsibilities

Project assessment and design leadership

• Attend client meetings to understand project requirements, scope, site constraints, and technical expectations.


• Visit project sites and assess feasibility, topography, access, geotechnical conditions, drainage, and other design considerations.

Lead design and engineering from initial assessment and concept development through detailed design and construction support.

• Manage design schedules, deliverables, reviews, approvals, and coordination across disciplines.

BESS Design & Engineering

• Lead conceptual, basic, and detailed engineering for BESS projects.


• Develop BESS system architecture, sizing, capacity calculations, and technical configurations based on project requirements.


• Evaluate battery technologies, PCS, BMS, EMS, transformers, switchgear, and auxiliary systems.


• Prepare and review Single Line Diagrams (SLDs), electrical layouts, cable schedules, equipment specifications, and technical drawings.


• Ensure optimum battery sizing, power-to-energy ratio, round-trip efficiency, degradation considerations, and system performance.

Solar plant and electrical design

• Lead PV plant design, including module selection and configuration, stringing, DC/AC sizing, inverter selection, and plant layout.


• Develop and review single-line diagrams (SLDs), electrical layouts, cable schedules, equipment specifications, and other technical drawings.


• Design or oversee DC and AC cable sizing and routing, earthing and lightning protection, transformers, switchgear, protection, and plant electrical systems.


• Coordinate grid-connection and plant-interface requirements with the client, utility, and relevant consultants.
