Field Applications Engineer (NCG) – Datacenter & Power Solutions

Job Title

Field Applications Engineer (NCG) – Datacenter & Power Solutions

Role Summary

Support customer designs and validation for high-current power delivery and digital multiphase power solutions used in AI, datacenter, server, and networking systems. Work with Field Applications and Power Systems Engineers to characterize, troubleshoot, and optimize power-management solutions.

This role is based in Austin, Texas, and uses Renesas' West Lake Hills laboratory for hands-on validation, testing, and customer support.

Experience Level

Entry-level - recent graduate. Suitable for candidates with internship/co-op or 0–2 years of relevant experience in power electronics or hardware validation.

Responsibilities

Primary responsibilities include customer support, laboratory validation, and technical collaboration to enable product adoption and design wins.

• Support strategic customer programs from concept through validation and production alongside senior FAE engineers.
• Validate, characterize, and optimize digital multiphase power solutions for AI, cloud, server, and networking applications.
• Perform hands-on laboratory testing: efficiency characterization, load-transient testing, power sequencing validation, telemetry verification, protection validation, fault analysis, and rail measurement.
• Support customer board bring-up, power-supply debug, and system-level validation activities.
• Participate in schematic reviews, component selection, and PCB layout reviews for high-current power delivery systems.
• Produce technical reports, characterization summaries, validation documentation, and customer-facing presentations.
• Use industry-standard test equipment and contribute to automated validation and data-analysis workflows.
• Collaborate with Product Marketing, Applications Engineering, Product Line Management, and Sales to support customer engagements.
• Develop skills and experience to progress toward independent customer support and troubleshooting.

Requirements

Must-have technical skills and location/working requirements are listed below. Preferred skills are noted separately.

• Foundation in power electronics, analog circuit design, DC-DC converters, switching power supplies, feedback control loops, and circuit analysis.
• Practical experience with lab test equipment (oscilloscopes, electronic loads, power analyzers, source-measure units) or demonstrated ability to learn them quickly.
• Strong written and verbal communication skills and ability to work in cross-functional teams.
• Demonstrated ability to solve complex technical problems in a team environment.
• Willingness to travel periodically to customer sites and to work regularly in a laboratory environment.
• Must be located in, or willing to relocate to, the Austin, TX area with regular access to Renesas' Austin laboratory and local customer sites.

Nice-to-have / preferred:

• Internship, co-op, undergraduate research, or industry experience in power electronics, power-supply design, hardware validation, or semiconductor applications engineering.
• Experience with switching power-supply design, simulation tools (LTspice, PSpice, SIMPLIS, MATLAB/Simulink), scripting for test automation (Python, MATLAB), and PCB layout considerations for power delivery.
• Experience building automated validation methodologies and data-analysis workflows.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or a closely related engineering discipline. The posting targets recent graduates or candidates expecting to graduate before the anticipated start date; relevant internships, co-ops, or equivalent project experience are noted as preferred.
