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

About the role:

As a Senior Hardware Engineer, you will own and drive DC and AC interconnection and safety compliance alongside other mechanical and electrical hardware engineers for MW/MWh-scale utility inverter and Battery Energy Storage Systems (BESS) serving data centers, spanning outdoor cabinets and containerized platforms.

This role requires hands-on experience in high-voltage DC and AC interconnection system design, involving 800V–1500V DC battery voltages and 277/480V AC voltages, necessary for BESS safety compliance. You will work closely with system engineers, controls engineers, and mechanical engineering to ensure the product meets safety, performance, reliability, manufacturability, serviceability, and cost targets — delivering production-ready designs from concept through deployment while optimizing BOM cost.

What will you do: 

• Develop HV DC and AC solutions for utility-scale systems, interconnecting multiple inverter DC inputs to the battery and inverter AC outputs to the grid, throughout the full product lifecycle.

• Work in cross-functional teams of system integration, mechanical, and inverter hardware engineers.
• Specify, design, verify, and debug complex busbars, wiring, interlocks, protection circuits, and sequencing for high-voltage DC and AC interconnections.
• 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.
• Provide guidance to mechanical assembly, firmware monitoring and control, PCB layout, and compliance engineers.
• Lead efforts to meet thermal and safety requirements for BESS applications (UL and IEC) 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 DC and AC interconnection subject matter expert for current and next-generation platforms.

Who You Are and What You Will Bring:

B.E. with 5+ years of relevant industry experience, or a Master's degree with 3+ years of relevant industry experience, with an electrical engineering background.

• Proven track record integrating high-voltage DC and AC interconnection solutions in commercial/industrial products.
• Proficiency in analytical, tolerance, and 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 electronics and electro-mechanical hardware design, troubleshooting, and problem-solving skills.
• Hands-on experience with Python and embedded software for inverter controls development, within a test automation environment.
• High-voltage DC and AC interconnections with safety compliance.
  
  
• Electronics and electro-mechanical design and development for high-volume manufacturing.
  
  
• Field quality improvement and cost reduction through Value Analysis/Value Engineering (VAVE).
