About the Role

As a Staff Hardware Engineer, you will contribute to 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 you will 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 bring

• B.E. in Electrical Engineering with 8+ years of relevant industry experience, or a Master's degree in Electrical Engineering with 6+ 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 projects, influencing architecture decisions, and mentoring engineers.

What will make you stand out

Subject matter expertise in two or more of the following:

• 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.
