Senior Applications Engineer

Job Title

Senior Applications Engineer

Role Summary

Member of the Power Management business unit responsible for driving adoption of Renesas power-management solutions. Works with product definition, marketing, and field teams to enable customer designs and define next-generation DC-DC and multiphase power solutions.

Primary activities include hardware evaluation, circuit simulation, system-level debugging, and developing application materials and trainings to support internal teams and customers.

Experience Level

Senior — typically 7+ years of relevant experience (or 5+ years with a relevant Master’s degree).

Responsibilities

Key responsibilities include technical customer enablement, product definition, and system-level support.

• Lead product promotion and design-in activities, including power-tree architecture and power-delivery system debugging.
• Contribute to product definition based on technical requirements and market needs.
• Review schematics and PCB layouts for evaluation boards and customer designs.
• Develop and run simulations of power converter circuits and systems to resolve technical issues.
• Author technical documentation such as application notes and design guidelines.
• Provide technical training on DC-DC converters and product usage to FAEs and customer engineers.
• Provide on-site and remote technical support, including root-cause analysis and debugging.
• Conduct competitive analysis and market research to inform marketing and strategy.
• Maintain a system-level understanding of customer applications to inform new product development.

Requirements

Must-have technical skills and experience.

• Extensive experience with power ICs, MOSFETs, control loops, digital controllers, and multiphase buck converters.
• Required experience with analog circuit modeling and simulation tools (e.g., SIMPLIS, PSpice).
• Proficiency with lab equipment: oscilloscopes, electronic loads, function generators; experience automating lab equipment (Python or C) is a strong benefit.
• Familiarity with schematic capture and PCB design tools such as OrCAD, Allegro, and Cadence.
• Solid knowledge of DC/DC converter topologies (buck, boost, buck-boost, charge pump, intermediate bus converters) and control theory, including closed-loop compensation and stability margin analysis.
• Ability to perform system-level debugging and root-cause analysis in complex power-delivery systems.
• Strong written and verbal communication skills for documentation and training.
• Nice-to-have: familiarity with Intel SVID/AMD SVI and PMBus/AVSBus interfaces; experience with lab equipment automation and scripting.

Education Requirements

Bachelor of Science in Electrical Engineering (BSEE) or Electrical/Computer Engineering (BSECE) with 7+ years of relevant experience, or Master of Science in Electrical Engineering (MSEE) preferred with 5+ years of experience.
