Principal Application Engineer

This role provides technical leadership across strategic customers, platforms, products, and technical disciplines. Deep knowledge of DC/DC power conversion and digital multiphase power systems is required. Key responsibilities include:

• Lead alignment with key stakeholders on critical technical risks, program priorities, schedules, and next steps.

• Travel to customer and partner sites to lead resolution of critical digital multiphase power and system-level issues.

• Guide Marketing and product teams with strategic customer, platform, competitive, and market insight.

• Lead advanced system validation of vertical and lateral power stages and controller products. Establish validation direction and provide technical findings that influence product architecture and design decisions.

• Develop and guide technical collateral, design methodology, performance analysis, and application guidance for strategic customer engagement and broader market adoption.

• Mentor Applications Engineers and Field Applications Engineers and establish reusable technical methods across the organization.

• Translate strategic customer and CPU, GPU, and ASIC platform requirements into power architecture, product requirements, and technical trade-offs.

• Establish advanced analysis, simulation, power delivery network (PDN), and validation methods for next-generation controllers, Smart Power Stages (SPS), and power-delivery solutions.

• Develop new technical methods, architectures, and intellectual property that differentiate Renesas solutions and support design-in and market adoption.

• Bachelor’s degree in Electrical Engineering or a related field; a Master’s degree in power electronics is preferred.

• Typically 15+ years of experience in the power management industry, or equivalent experience.

• Experience supporting SPS, with a good understanding of key power MOSFET parameters.

• Experience with digitally enabled power management products and multiphase applications.

• Advanced understanding of control-loop theory, including voltage-mode, current-mode, and constant-on-time control, compensation networks, system interactions, and their application in power converters.

• Deep knowledge of mixed-signal integrated circuits, system-level interactions, and design trade-offs.

• Advanced hands-on experience with SIMPLIS or equivalent power simulation tools and PDN analysis, including correlation between models, silicon, and platform measurements.

• Advanced hands-on proficiency with lab equipment, including loop gain analyzers, oscilloscopes, electronic loads, and function generators, with the ability to establish measurement and validation strategies.

• Ability to travel to customer and partner sites in Asia and the United States, including extended on-site support when required.
