Senior Power Electronics Engineer; Raleigh, NC

General Summary

Qualcomm is developing an exciting new product line for machine learning inference acceleration in the cloud with industry‑leading performance per watt. As part of this project Qualcomm is seeking an experienced power electronics engineer. The role will cover all aspects of product development, including (but not limited to) specifying board‑level power design, power‑management products and voltage‑regulator selection, development, programming, debugging, as well as post‑silicon board/SoC test validation and power‑correlation to ensure system‑level performance and power metrics are met.

• Requires expertise in one or more of the following engineering disciplines: power electronics (switch‑mode and linear), power management, high‑bandwidth/low‑latency control interfaces, thermal analysis, power distribution networks, PCB layout and construction, and industry‑standard interfaces (e.g. SPI/I2C, AVS, PMBus, etc).
• Expertise with multi‑phase buck, boost, intermediate‑bus converters, LDO regulators as well as eFuse, hot‑swap controllers, voltage‑level‑translators, differential amplifiers, voltage and current‑sensing telemetry.
• Uses design and simulation tools such as SIMPLIS and MATLAB, or other common industry VR simulation tools.
• Works with power, system, board architecture, and other cross‑organization colleagues to ensure the board meets requirements to the SoC.
• Provides schematic/layout guidance to the CAD team and conducts design reviews following internal and industry‑established guidelines.
• Helps drive internal simulation teams to ensure the board design meets signal and power integrity (SI/PI), including (but not limited to) impedance analysis, IR‑drop analysis, and transient droop/overshoot for all rails.
• Especially critical to be able to work with a degree of abstraction and ambiguity.
• Derives, documents, and executes board‑validation test plans pre‑/post‑silicon in the lab. Brings up and tests prototypes utilizing typical lab test equipment (oscilloscopes, multi‑meters, electronic loads, passive/active/power probes, T32 debuggers, etc.) and runs power‑stress type workloads to analyze voltage‑regulator performance.
• Drives triage of problems at the system‑level to determine root cause, analyzes test results ensuring sufficient design margins have been achieved, provides feedback to teams to implement changes as required, and supports SoC, software and firmware teams during development.
• Tracks industry technology trends, interacts with other technology teams, and provides technical expertise for next‑generation initiatives.
