Job Description

REMOTE - MUST BE IN SOUTHERN CALIFORNIA - PREFERRED ORANGE COUNTY (LA and San Diego included too.)

Applicants for this position must be currently authorized to work in the United States on a full-time basis. Renesas is unable to sponsor applicants for work visas for this position now or in the future.   

We are seeking a highly motivated Staff Field Applications Engineer (Analog & Power) to join our team. This role will serve as the technical lead for power and analog solutions, supporting system-level design engagements across key customers, including pre- and post-design support activities such as schematic review, component selection, technical resource guidance, and issue resolution to help drive design-in to design-win success.

The FAE will:

• Lead customer power architecture development, including power tree design, device selection, and system optimization
• Perform technical design reviews, root-cause analysis, and hands-on debug for complex analog and power-related issues
• Drive new product evaluations and competitive positioning for Renesas power and analog portfolio (PMICs, DC/DC, LDOs, battery management, signal chain)
• Execute extensive hands-on lab work, including board bring-up, measurement, validation, and failure analysis
• Support system-level design integration, ensuring alignment between power, processor, and connectivity subsystems
• Provide direct technical guidance to customers to accelerate designs from concept to production revenue
• Deliver field feedback to product divisions, influencing roadmap, feature prioritization, and system solution gaps
• Develop and present customer trainings, technical seminars, and internal enablement content

Success in this role requires the ability to translate component-level expertise into system-level solutions, while building strong, trusted relationships with customers and internal teams.
