About The Position

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.
