Sr Staff System Engineer

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. Hybrid - This role may sit in San Jose, CA; Phoenix, AZ; or Chandler, AZ (local candidates to these cities preferred - no relocation) This role sits within our Low-Voltage GaN Marketing & Systems Group, acting as a Sr Staff System Engineer to define the future of our power semiconductor portfolio. In this strategic role, you will not simply support existing products—you will be the technical authority responsible for driving next-generation IC product definition, silicon architectures, and long-term roadmap strategy. By leveraging deep expertise in low-voltage (<400V) BLDC and PMSM motor control, you will identify market gaps across high-growth applications (robotics, humanoids, e- mobility, power tools) and translate complex system-level challenges into actionable silicon-level requirements to deliver highly differentiated, system-optimized products. Key Responsibilities • Product Definition & Specs: Translate system-level application requirements into detailed IC specifications (e.g., Rds-on targets, gate drive source/sink strength, dead-time control, protection features like OCP/OTP, packaging thermal constraints, and monolithically integrated features). • Architecture & Strategy: Develop and influence future chip architectures based on system-level understanding of GaN-based power stage and driver IP and sensing topologies. Drive the multi-year technology roadmap aligned with emerging market trends. • Silicon & Cross-Functional Collaboration: Collaborate closely with IC Design, R&D, and Marketing teams to ensure silicon implementation matches application realities. Balance system performance, silicon die area, cost targets, and time-to- market. • Prototype & Reference Design Development: Design, schematic-capture, layout, and validate high-power-density system-l
