Experience: 5–10 years
Function: R&D; / Power Electronics
Location: Bangalore, India
Business Area: Utility-Scale PV Inverters, BESS PCS & Microgrid Systems
Employment Type: Full time
About the role:
We are looking for a System Architect / Senior System Design Engineer to lead the hardware architecture and system-level design of utility-scale PV inverters and Battery Energy Storage System (BESS) Power Conversion Systems (PCS). The role requires solid hands-on expertise in power-converter design, system architecture, electrical integration, and product development from concept through certification and field deployment.
Key responsibilities:
Define system architecture and hardware design for utility-scale PV inverters and BESS PCS in the MW power range.
Develop power-stage architecture, including power semiconductors, DC-link, AC filter, busbars, magnetic components, and protection systems.
Design and optimize high-power inverter / PCS hardware, including thermal management, switching strategy, efficiency, power density, and reliability.




Develop grid-connected and grid-forming (GFM) converter architectures, including grid synchronization, fault ride-through, reactive power, and power-quality requirements.
Design DC and AC interfaces for PV, battery, transformer, and grid connections, including isolation, protection, and grounding.
Lead system-level electrical design, including SLDs, operating modes, ratings, overload capability, and fault-current withstand.
Coordinate with control, firmware, mechanical, thermal, EMC, and certification teams to ensure successful product integration.
Support component selection, derating, reliability analysis, and design reviews for power semiconductors, capacitors, inductors, transformers, and protection devices.
Develop and review design calculations, simulations, prototypes, and validation plans for power-conversion systems.
Lead DVT/PVT, type testing, EMC/EMI, safety, and certification activities for IEC/UL-comp
