Power Electrical Engineer

Position: Power Electrical Engineer

Location: Sunnyvale, CA (Onsite)

We are seeking an experienced Power Validation Engineer to join our AI Glass hardware validation team. This role is responsible for validating and optimizing power consumption across Meta''s AI-enabled smart glasses. The ideal candidate will drive power measurement, analysis, and regression debugging to ensure optimal battery life and thermal performance . You will collaborate closely with hardware design, firmware, and AI/ML teams to deliver power-efficient products that meet consumer expectations.

What You Will Do:

• Lead power validation of AI Glass products across all device use cases 
• Design, develop, and execute comprehensive power measurement test plans for wearable devices in an on-site lab environment.
• Debug power regressions by analyzing electrical measurements, device logs, firmware power state transitions, and system-level interactions.
• Characterize power consumption across various operating conditions (temperature, voltage corners, workloads) and identify optimization opportunities.
• Collaborate with firmware and software teams to validate power management features.
• Develop and maintain automated power measurement test infrastructure using Python-based scripting and data acquisition systems.
• Prepare comprehensive test reports with data-driven analysis and effectively communicate findings and progress to cross-functional stakeholders.
• Support power budgeting and battery life estimation for new product development and feature additions.
• Identify and drive resolution of power-related issues found during validation, working with design and firmware teams on root-cause analysis and corrective actions.

What You Will Bring:

• 5+ years of experience in power consumption measurement and validation of embedded electronic products.
• Experience with power validation on battery-powered consumer electronics, wearables, or small form factor devices.
• Strong expertise in power consumption measurement techniques and methodologies for various device use cases .
• Solid knowledge of electronics circuits, power management ICs, voltage regulators, and battery charging systems.
• Proficiency with electronics lab test and measurement equipment (oscilloscopes, power analyzers, source-measure units, data acquisition systems, current probes).
• Hands-on experience with hardware testing on small form factor PCBs and wearable devices.
• Good knowledge of microprocessors/controllers, SoCs, and digital communication protocols (I2C, SPI, UART, USB).
• Strong analytical and problem-solving skills with ability to interpret complex power data and identify root causes.
• Excellent communication skills with ability to present technical findings to diverse audiences.

Preferred Qualifications:

• Experience with programming and automated test system design for hardware validations.
• Familiarity with AI/ML workload characterization and power profiling of neural network accelerators.
• Experience with wireless protocol power optimization (Wi-Fi, Bluetooth, cellular).
• Knowledge of battery management systems, fuel gauging, and battery life modeling.
• Experience with thermal management and correlation of power/thermal behavior.
• Familiarity with power management frameworks in embedded Linux or RTOS environments.
• Experience with data visualization tools and statistical analysis for power data interpretation.
