Principal Validation Engineer

Job Description

We are seeking a highly experienced and deeply hands-on Principal Validation Engineer to join our dynamic Silicon Validation team in Bengaluru. In this critical role, you will serve as a technical architect 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 and senior validation engineers, fostering a culture of technical excellence. Responsibilities: Technical Leadership & Architecture: Serve as the primary technical expert for post-silicon validation of complex DC-DC converter products (e.g., LDO, Buck, Boost, Buck-boost, Drivers, Controllers, etc ). Architect 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 advanced 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 deep technical mentorship and guidance to junior and senior validation engineers on DC-DC converter principles, validation methodologies, test planning, debugging techniques, and best practices. Foster a strong 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 key technical liaison 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 all 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: 12+ years of extensive, hands-on experience in Electrical/Electronics Post-Silicon Validation, with a significant focus on DC-DC converters and power management ICs. Deep technical expertise 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). Strong 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. Mastery 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 across various corners (PVT), operating modes, and stress conditions. Familiarity with industry-standard EDA tools for schematic/layout viewing, simulation analysis, and potentially test pattern generation (e.g., Cadence Virtuoso/Spectre, Siemens Calibre, Synopsys Verdi, etc.). Excellent communication, interpersonal, and mentorship skills. Ability to work effectively in a hybrid work environment with a strong presence in the Bengaluru lab. Qualifications: Bachelors or Masters degree in Electrical Engineering, Electronics Engineering, or a related field. Why Join Our Team: This is a unique opportunity to be a foundational technical leader in our growing Silicon Validation team in India. You will play a pivotal role in bringing cutting-edge DC-DC products to market, shaping our validation methodologies, and directly contributing to the technical growth of your team members. If you are passionate about power electronics, enjoy hands-on validation, and thrive in a mentorship role, we encourage you to apply.
