Electrical Engineer

About the role

We are looking for an electrical engineer to own the end-to-end power architecture of our next-generation portable devices. You will be responsible for ensuring our products are safe, efficient, and long-lasting. From selecting the right battery chemistry to fine-tuning PMIC registers and creating complex power models, you will ensure every milliwatt is accounted for.

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

Requirements

• Education: BS/MS in Electrical Engineering.
• PMIC Expertise: Hands-on experience integrating and configuring high-performance PMICs (e.g., Qualcomm, TI, Nordic, or Maxim).
• Battery Tech: Deep understanding of Battery Management Systems (BMS), including fuel gauging algorithms and state-of-charge (SoC) estimation.
• Precision Measurement: Expert-level skills using power analyzers, electronic loads, and high-resolution current sense tools.
• PDN Integrity: Strong understanding of PCB layout for power, focusing on minimizing losses and managing high-current paths.
• Bonus Qualifications
• Software Familiarity: Experience working with software team on driver-level power management or I2C/SMBus communication.
• Thermal Modeling: Experience using tools like Flotherm or Icepak to simulate the thermal impact of power dissipation.
• Simulation: Proficiency in SPICE or MATLAB for transient analysis and loop stability modeling.
