Wireless/Inductive Charging Electrical Engineer

About the Team:

OpenAI is seeking an experienced Electrical Engineer with expertise in wireless (inductive/resonant) power transfer to design and optimize next-generation charging technologies for high-performance hardware products. You will own the end-to-end charging architecture—from coil design and power electronics to system integration, regulatory compliance, and manufacturing ramp-up.

About the Role:

Architecture & Design

• Develop and refine high-efficiency inductive and resonant charging topologies.

• Design and optimize transmit and receive coils, shielding, and magnetic materials to meet coupling, EMI, and thermal performance targets.

Power Electronics

• Implement synchronous rectifiers and control loops (voltage, current, FOD) using discrete components and PMIC solutions.

• Specify and characterize power components and networks to achieve >90% end-to-end efficiency.

System Integration

• Collaborate with mechanical, RF, battery, and firmware teams to ensure robust alignment tolerance, thermal performance, and communication (I²C, SWD, NFC) between charger, fuel-gauge, and system controllers.

• Lead PCB layout for low-loss, high-frequency paths (100 kHz – 6.78 MHz), minimizing parasitics and ensuring controlled impedance and isolation.

Verification & Compliance

• Plan and execute validation for power, thermal, EMI/EMC, and safety certification.

• Conduct failure analysis (FMEA), address field data, and implement countermeasures to maximize reliability and safety.

Manufacturing & Test

• Define DFM/DFT requirements, production test limits, and fixture design for coil characterization, calibration, and performance screening.

• Support factory builds and resolve power-related yield issues.

Technology Leadership

• Build internal wireless-power expertise, mentor junior engineers, and evaluate emerging materials and semiconductor technologies.

Qualifications:

• 5+ years designing wireless or inductive charging systems for high-volume consumer or hardware products.

• Hands-on experience with:

  • Qi/resonant wireless-power standards and compliance.

  • Analog/power electronics design up to ~100 W (switch-mode converters, resonant tanks, synchronous rectification).

  • Coil, magnetics, and shielding simulation (Maxwell, HFSS, Flux, or similar) and SPICE-based circuit modeling.

  • EMI/EMC mitigation, thermal modeling, and safety-critical design.

  • Schematic capture and multilayer PCB layout (Altium, Cadence, or similar) with SI/PI and thermal reviews.

• Strong lab and debug skills: oscilloscopes, VNAs, power analyzers, thermal cameras, and Python/C test automation.

• Ability to work cross-functionally in fast-paced development cycles.

Preferred Qualifications

• Shipped at least one Qi-certified product at >1 M units.

• Experience with adaptive FOD and inductive communication protocols.

• Familiarity with battery pack design, fuel-gauge algorithms, and charging profiles.

• Knowledge of global regulatory requirements (KC, CRF, CE RED, PSE, WPC) and third-party test-house engagement.

• Master’s degree (MSEE) or higher, with a focus in power electronics or electromagnetics.
