About the role

Electrical engineer responsible for end-to-end power architecture of next-generation portable devices, ensuring safe, efficient, and long-lasting power systems from battery chemistry to PMICs, modeling, charging, and regulatory compliance.

Responsibilities

  • Power Architecture: Define the power distribution network (PDN) and select key components, including PMICs, chargers, fuel gauges, and protection ICs.
  • Battery Management: Lead the selection, characterization, and safety validation of Li-ion/Li-poly battery cells.
  • Power Modeling & Simulation: Develop detailed power models to predict battery life across various user scenarios (idle, peak load, standby).
  • Charging Systems: Design and optimize wired (USB-C PD) and/or wireless charging circuits, ensuring thermal stability and fast-charging compliance.
  • Efficiency Analysis: Conduct bench-level efficiency measurements for DC-DC converters (Buck, Boost, LDO) and optimize firmware settings for peak performance.
  • Peak Power Management: Develop power model and management strategy to overcome system brownout.
  • Regulatory Compliance: Ensure power designs meet global safety standards (UL, IEC, UN38.3) and EMI/EMC requirements.

Qualifications

  • BS/MS in Electrical Engineering.
  • Hands-on experience integrating and configuring high-performance PMICs (e.g., Qualcomm, TI, Nordic, or Maxim).
  • Deep understanding of Battery Management Systems (BMS), including fuel gauging algorithms and state-of-charge (SoC) estimation.
  • Expert-level skills using power analyzers, electronic loads, and high-resolution current sense tools.
  • Strong understanding of PCB layout for power, focusing on minimizing losses and managing high-current paths.
