Head-R&D

Why Join Us?

• Be part of a fast-growing BESS and renewable energy solutions company at the

forefront of India’s energy-transition and grid-stabilization projects.

• Work on cutting-edge utility-scale and industrial BESS projects with exposure to

international OEMs, advanced BMS/EMS, and grid-interactive systems.

• Collaborate with a strong technical team in Ahmedabad, with opportunities to

influence design standards, technology choices, and market-ready

productization of BESS solutions.

Key Roles & Responsibilities

• Lead the electrical design and system architecture of BESS projects (1 MWh to

100+MWh), including HV/LV systems, switchgear, transformers, HVAC and grid

interconnection.

• Prepare and review single-line diagrams, protection & control schematics, cable

routing, earthing/grounding, and auxiliary power systems aligned with Indian grid

codes and site conditions.

• Perform and review power system studies (load flow, short-circuit, protection

coordination, harmonics, stability) for BESS-integrated systems.

• Ensure designs comply with Indian standards (IS, CEA, BIS) and international

BESS standards (IEC 62933, UL 9540/1973, NFPA 855).

• Lead technical integration of battery racks, PCS/inverters, EMS, and BMS;

coordinate with control and software teams for protection logic and HMI/SCADA

integration.

• Prepare and review detailed electrical design packages (IFC, as-built), technical

specifications, datasheets, and vendor interface documents.

• Design and validate protection schemes, relay settings, and arc-flash/grounding

strategies for BESS facilities.

• Liaise with civil, structural, fire-protection, and HVAC teams to ensure safe and

constructable layouts for panels, cabling, and equipment.

• Provide site engineering and commissioning support: supervise installation,

pre-commissioning, and commissioning of BESS electrical systems and sign-off

on reports.

• Troubleshoot electrical and control-system issues, verify performance against

design and contractual requirements, and support O&M handover.

• Partner with BESS OEMs and suppliers to adapt designs for Indian voltage levels,

ambient conditions, and grid-code requirements.

• Support proposal and tender engineering by providing BESS electrical inputs,

technical responses, and lifecycle-cost-optimized solutions.

• Develop and maintain internal design guidelines, templates, and best-practice

documents for BESS electrical engineering.

• Stay updated on emerging battery chemistries, power conversion technologies,

and regulatory changes in India.

Qualifications & Experience

• B.E./B.Tech or M.E./M.Tech in Electrical Engineering (or equivalent).

• 7–12 years of experience in power systems, with 3–5 years in BESS,

solar-plus-storage, or similar storage projects.

• Strong knowledge of Indian grid codes, CEA regulations, IS/IEC standards, HV/LV

systems, protection relays, switchgear, and BESS components.

• Proficiency in ETAP / CYME / DIgSILENT and AutoCAD Electrical (or similar tools).

• Experience in utility-scale or industrial BESS / hybrid renewable projects.

• Familiarity with arc-flash studies, grounding design, and safety standards for

BESS installations.

• Strong communication, client-facing, and cross-functional coordination skills
