As a global team, our employees actively embody the Renesas Culture, our guiding principles based on five key elements: Transparent, Agile, Global, Innovative, and Entrepreneurial. Renesas believes in, and has a commitment to, diversity and inclusion, with initiatives and a leadership team dedicated to its resources and values. At Renesas, we want to build a sustainable future where technology helps make our lives easier. Join us and build your future by being part of what’s next in electronics and the world.   About the Role: We are seeking a highly experienced and deeply hands-on Staff Validation Engineer to join our dynamic Silicon Validation team in Bengaluru. In this critical role, you will serve as a technical lead and mentor, driving the post-silicon validation of cutting-edge DC-DC converter products. Your profound expertise in power electronics, silicon validation methodologies, and PCB design will be instrumental in ensuring the quality, performance, and reliability of our next-generation power management ICs. You will not only lead complex validation efforts but also guide and technically ramp up junior validation engineers, fostering a culture of technical excellence. Responsibilities: • Technical Leadership & Architecture:• Technical lead for post-silicon validation of complex DC-DC converter products (e.g., LDO, Buck, Boost, Buck-boost, Drivers, Controllers, etc…). • Develop comprehensive validation test plans and methodologies from silicon bring-up to characterization, focusing on performance, reliability, and robust operation across various load and environmental conditions (including load transient, ripple, parasitic effects). • Drive the definition and implementation of validation techniques, including automated test development and data analysis. • Hands-on Validation & Debug:• Perform hands-on initial silicon bring-up, debugging, and characterization on the bench using advanced lab equipment (oscilloscopes, multimeters, logic analyzers, power supplies, SMUs, spectrum analyzers, network analyzers, thermal chambers, etc.). • Lead root cause analysis of complex silicon issues, collaborating closely with design, system, and test engineering teams to drive timely resolutions. • Develop custom test setups, validation boards (PCB schematics and layout review), and fixtures to thoroughly test DC-DC converter performance. • Mentorship & Guidance:• Provide technical mentorship and guidance to junior validation engineers on DC-DC converter principles, validation methodologies, test planning, debugging techniques, and best practices. • Foster a technical learning environment within the team, promoting knowledge sharing and continuous improvement. • Test Development & Automation:• Define requirements for, and potentially contribute to, the development of automated test scripts and frameworks for efficient validation execution. • Contribute to the selection, adoption, and optimization of validation tools and infrastructure to improve overall team efficiency. • Cross-Functional Collaboration:• Act as a lead between the Silicon Validation team and cross-functional teams including IC Design, System Design, Firmware, Product Engineering, and Application Engineering. • Drive effective communication of validation findings, risks, and recommendations to various stakeholders. • Quality & Compliance:• Ensure validation activities adhere to rigorous quality standards, functional safety requirements, and operational protocols (e.g., ESD, safety). • Contribute to the continuous improvement of validation processes (e.g., SWIFT process adoption) and documentation standards. Required Skills & Experience: • 9+ years of extensive, hands-on experience in Electrical/Electronic Post-Silicon Validation, with a significant focus on DC-DC converters and power management ICs. • Strong technical experience in DC-DC converter topologies (e.g., Buck, Boost, Buck-Boost, LDOs, Gate Drivers), control schemes, and their critical performance parameters (efficiency, ripple, load transient, stability, EMI/EMC). • Good proficiency in PCB schematics, layout review, and design considerations for high-frequency, high-current power circuits. Experience with validation board design is a significant plus. • Expert of bench validation methodologies and debugging techniques. Highly skilled in using and interpreting data from lab equipment such as high-bandwidth oscilloscopes, arbitrary waveform generators, electronic loads, network analyzers, spectrum analyzers, power meters, etc. • Proven ability to perform root cause analysis of complex silicon issues and drive solutions collaboratively with design teams. • Experience with test planning and execution for silicon validation ac
