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

About the role:

As a Senior Hardware Engineer - Sensors & Safety, BESS, you will own and drive sensor selection and safety compliance alongside other mechanical and embedded firmware 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 sensor system design across fire, smoke, hardware interlock, ground fault, pressure, temperature, and other sensor types necessary for BESS safety compliance. You will work closely with thermal engineers, DC and AC interconnection 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 sensor solutions for utility-scale systems across liquid cooling, chillers, and heat exchangers, throughout the full product lifecycle.
• Work in cross-functional teams of system integration, test automation, and inverter hardware engineers.
• Specify, design, verify, and debug complex sensor circuits for various cooling methods (liquid cooling, chillers, and heat exchangers) and 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 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 sensors 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.
• Proven track record integrating sensor solutions in commercial/industrial products.
• Proficiency in analytical, tolerance, and worst-case analysis (WCA), DPPM, DFMEA/AFMEA, and root-cause analysis for field failures.
• Experience with product lifecycle management (PLM) tools such as Arena or Agile for ECO, DEV, and ECR releases and Bill of Materials (BOM) management.
• Strong knowledge of circuit schematics, multi-layer PCB layout, EMI mitigation, and related simulation tools.
• 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.
• Sensors for liquid cooling and safety.
• Electronics and electro-mechanical design and development for high-volume manufacturing.
• Field quality improvement and cost reduction through Value Analysis/Value Engineering (VAVE).
