Staff Field Applications Engineer

We are seeking a highly skilled Staff Field Applications Engineer (FAE) to support strategic customers across datacenter, AI, server, and advanced computing markets. This role is based in the San Jose, CA area.

This role combines hands‑on technical ownership, system‑level power expertise, and customer‑facing leadership.

The ideal candidate brings deep experience in power electronics, and system bring‑up, with the ability to guide customers through complex programs from concept to production.

Renesas provides comprehensive training on our digital multiphase power solutions, ensuring new hire engineers quickly become experts in our architectures, tools, and validation methodologies.

Responsibilities:

1. Customer-Facing Technical Support

• Act as the lead technical interface for strategic customer accounts, supporting system‑level power architecture engagements from design concept to production.
• Provide expert guidance on digital multiphase power controllers, power modules, and server‑class power delivery systems.
• Support bring‑up, debug, schematic reviews, layout reviews, simulations, and full validation cycles.
• Generate customer-facing documentation such as program updates, validation reports, controller configuration files, waveforms, and issue closure reports.
• Assist customers during board validation, including VR compliance, SoC/GPU/ASIC domain interaction, and PDN‑related performance assessments.

2. VR Simulation & Validation

• Simulate VR solutions with application specific PDNs in SIMPLIS for early design feedback.
• Execute comprehensive validation of multiphase power solutions for datacenter and AI platforms, including transients, efficiency, telemetry, protection features, and fault response.
• Develop and maintain test plans, validation matrices, and use automated test flows to ensure full coverage of operating modes and edge cases.

3. Debug & Root‑Cause Analysis

• Diagnose complex issues using oscilloscopes, electronic loads, current probes, network analyzers, and automated instrumentation.
• Collaborate with design, systems, & applications teams to identify root cause and propose corrective actions.

4. Cross-Functional Collaboration

• Work closely with Sales, Product Line, and Marketing teams to provide customer-driven technical insights and influence product roadmaps.
• Support global engineering teams to ensure smooth program execution across schematic, layout, validation, and reporting phases.

5. Program Ownership & Execution

• Manage multiple customer programs simultaneously, track milestones, and risks.
• Ensure high‑quality execution during all phases of customer engagement and deliver timely updates to internal and external stakeholders.
