We are building teams that are designing, developing, and manufacturing next-generation energy technologies and our work environment is fast-paced, fun and full of exciting new projects.  

Must be available to work on-site at our Bangalore office 5 days per week.

About the role:

As a Sr. Staff Hardware Engineer, you will drive inverter development alongside other hardware and embedded firmware engineers for MW/MWh-scale utility Battery Energy Storage Systems (BESS) serving data centers, spanning outdoor cabinets and containerized platforms.

This role requires deep, hands-on expertise in inverter system design, thermal engineering, advanced simulation, and BESS safety compliance. You will work closely with thermal, site controls, sensor/safety, and manufacturing teams to ensure the product meets performance, reliability, manufacturability, serviceability, compliance, and cost targets — delivering production-ready designs from concept through deployment while optimizing BOM cost, CAPEX, and long-term OPEX.

What will you do: 

Develop new products and variants of power electronic converters across the full product lifecycle.

Work in cross-functional teams of system integration, test automation, and thermal engineers.

Specify, design, verify, and debug complex circuits across various inverter topologies.

Generate high-value ideas and transform them into platform-level designs.

Support system architecture, cost-reduction proposals, and failure root-cause analysis.

Engage with internal technical communities and contribute to cross-team knowledge sharing.

Mentor and grow junior engineers; provide guidance to PCB layout and compliance engineers.

Lead efforts to meet grid code requirements and certifications (UL and IEC) for BESS applications serving data centers.

Define engineering requirements, develop test plans, and deliver proofs of concept (POCs).

Champion technical excellence, rigorous documentation, and scientific discipline.

Serve as a subject matter expert for current and next-generation platforms.

Who You Are and What You Will Bring:

B.E. in Electrical Engineering with 12+ years of relevant industry experience, or a Master's degree in Electrical Engineering with 8+ years of relevant industry experience.

Proven track record developing high-power, high-voltage power electronics solutions from concept to market launch in commercial/industrial settings.

Experience developing device models for IGBTs, MOSFETs, and diodes, with accurate loss estimation using simulation tools.

Expertise in magnetic design and optimization, balancing cost and performance across product applications.

Proficiency in tolerance analysis, worst-case analysis (WCA), DPPM, DFMEA/AFMEA, and root-cause analysis for field failures.

Strong knowledge of circuit schematics, multi-layer PCB layout, EMI mitigation, and related simulation tools.

Working knowledge of inverter standards such as UL1741 and IEC 62109.

Hands-on experience with simulation tools such as LTspice, MATLAB/Simulink, and PLECS.

Experience with product lifecycle management (PLM) tools such as Arena or Agile for ECO, DEV, and ECR releases and Bill of Materials (BOM) management.

Demonstrated power electronics hardware design, troubleshooting, and problem-solving skills.

Hands-on experience with Python and embedded software for inverter controls development, within a test automation environment.

Strong system-level understanding of PCS architectures, battery rooms, DC- vs. AC-coupled systems, and thermal coordination with BMS, site energy management systems, and PCS derating logic.

Demonstrated technical leadership: leading programs, influencing architecture decisions, and mentoring senior and staff-level engineers.

Power electronics circuits, power supply, and inverter topologies.

End-to-end electronics design and development for high-volume manufacturing.

Field quality improvement and cost reduction through Value Analysis/Value Engineering (VAVE).

Resonant converter topologies, control techniques, and GaN devices.
