Role Purpose

The Staff Applications Engineer will support Renesas input protection products for enterprise, data center, AI server, telecom, and industrial power systems. This is a hands-on hardware role focused on customer support, board debug, validation, reference designs, and practical design guidance and requires strong power electronics experience . The engineer will work with systems, design, validation, product marketing, field teams, and customers to solve real application issues and help customers adopt Renesas power products successfully.

Principal Accountabilities

- Provide applications support for input protection devices used in 48 V and emerging 800 V / 400 V power systems.
- Support customers and field teams through schematic reviews, PCB layout reviews, component selection, bench debug, issue reproduction, root cause analysis, and clear design recommendations.
- Develop and validate evaluation boards, demo boards, proof of concept hardware, and reference designs for high current and high voltage applications.
- Debug hardware, register configuration, PMBus/I C communication, gate drive behavior, isolation interfaces, system transients, and customer board failures.
- Use lab equipment such as oscilloscopes, high voltage supplies, electronic loads, power analyzers, thermal tools, differential probes, and automated test setups.
- Create scripts, calculators, GUI utilities, and data analysis tools to support validation, characterization, and customer debug.
- Support recent silicon bring up, identify application gaps early,



and work with design and systems teams to improve product robustness.
- Review and write customer documentation such as datasheets, application notes, user guides, design guides, test reports, troubleshooting notes, and training material.
- Work closely with marketing, systems, design, validation, quality, sales, and field teams to support product launch, customer design in, and issue closure.

Minimum Qualifications

- Master s degree in Electrical Engineering, Electronics Engineering, Power Electronics, or a related field; bachelor s degree with strong relevant experience may also be considered.
- 3+ years of experience in applications engineering, field applications, validation, product engineering, or hardware development for analog or power semiconductor products.
- Strong hands-on board and system debug experience, including issue reproduction, waveform analysis, fault isolation, root cause troubleshooting, and corrective action recommendations.
- Good understanding of power electronics, input protection, MOSFETs gate drive, current sensing, thermal behavior, and protection concepts.
- Experience with schematic capture, PCB layout review, board bring up, high current routing, grounding, noise coupling, isolation, and measurement best practices.




- Familiarity with simulation tools such as PSpice, SIMPLIS, MATLAB/Simulink, or similar tools for power, transient, thermal, or signal/power integrity analysis.
- Comfortable using common lab equipment, including oscilloscopes, power supplies, electronic loads, power analyzers, thermal cameras, probes, and solder/rework tools.
- Able to write clear customer facing documents and work directly with customers and cross-functional engineering teams. Qualifications

Preferred Qualifications / Desired Experience

- Experience with high voltage products, 800 V or 400 V HVDC systems, solid state relays, eFuses, live insertion, or high power data center systems.
- Knowledge of PMBus/I C telemetry, register configuration, fault logging, GUI tools, and lab automation using Python, C/C++, MATLAB, LabVIEW, or similar tools.
- Experience validating startup into large capacitance, short circuit behavior, load transients, retry/latch off behavior, and safe operating area limits.
- Familiarity with isolation concepts, isolated interfaces, bias supplies, HV lab safety, EMI, and ESD considerations.
- Experience creating EVMs, reference designs, demo platforms, user guides, application notes, design calculators, and training material.
- Customer facing experience with enterprise or data center customers, server OEMs/ODMs, hyperscalers, telecom customers, or field applications teams.

Able to manage ambiguity, prioritize customer issues, and drive practical solutions with limited day to day direction.
