Head of R&D; – Battery Energy Storage Systems (BESS)
Location: Bangalore
Div: L&T; – EPS – Power Electronics and BESS
Role Overview
The Head of R&D; – BESS leads the end-to-end research, design, and development of utility-scale and industrial battery energy storage solutions. This role oversees multi-disciplinary engineering teams (electrical, mechanical, thermal, firmware, software, controls, power electronics, cell/pack engineering, and validation) and drives innovation, product roadmap execution, technology strategy, and platform development.

Key Responsibilities
Technology Strategy & Roadmap
Define the 3–5-year technology roadmap for BESS products: cells, modules, packs, PCS integration, BMS, EMS, safety, and cooling.
Evaluate emerging technologies (LFP/NMC cell innovations, sodium-ion, solid-state, liquid-cooled designs, advanced PCS topologies, hybrid systems).
Lead competitive benchmarking and cost-performance improvement programs.
2. End-to-End Product Development Leadership
Own the full product lifecycle:



concept → design → prototype → validation → certification → release to manufacturing.
Oversee development of utility-scale BESS platforms (1–5 MWh containers) and industrial BESS products.
Drive cell-to-pack development (module structure, pack architecture, thermal pathways, safety features).
Ensure alignment with standards (UL 9540/9540A, UL 1973, IEC 62933, IEEE, CE, BIS).
3. Cross-Functional Engineering Management
Lead R&D; teams across all function -Electrical & Power electronics, Mechanical/Structural design, Thermal & Cooling systems, Battery module/pack engineering, BMS/EMS controls & firmware development, System engineering & safety, Testing & validation
Build solid collaboration with Product Management, Operations, Quality, Supply Chain, and Field Engineering teams.
4. Innovation, IP, and Advanced Engineering
File patents for thermal management, module designs, battery controls, fire mitigation systems, etc.
