About the job
Be part of a team that pushes boundaries, developing custom silicon solutions that power the future of Google's direct-to-consumer products. You'll contribute to the innovation behind products loved by millions worldwide. Your expertise will shape the next generation of hardware experiences, delivering unparalleled performance, efficiency, and integration.
As a HSIO IP Validation Engineer, you'll help evaluate, test, characterize, and qualify the High-Speed I/O (HSIO) IPs that are part of Google’s System-on-Chips (SoCs). In this role, you will be responsible for all aspects of post-silicon validation for critical HSIO interfaces like PCIe, USB, UFS, Mobile Industry Processor Interface (MIPI) (C-PHY/D-PHY), and DisplayPort that power our latest mobile phones, wearables, tablets, and laptops.
Google's mission is to organize the world's information and make it universally accessible and useful. Our team combines the best of Google AI, Software, and Hardware to create radically helpful experiences. We research, design, and develop new technologies and hardware to make computing faster, seamless, and more powerful. We aim to make people's lives better through technology.
Responsibilities
- Own bench-level design validation and electrical compliance for High-Speed Serial Interfaces (MIPI M-PHY, USB3.2), ensuring certification readiness across PVT operating conditions.
- Characterize signal and power integrity using oscilloscopes, BERTs, and VNAs to perform advanced analysis including eye diagrams, Jitter decomposition, and receiver (Rx) tolerance.
- Collaborate with cross-functional teams to root-cause complex PHY-level electrical issues and protocol link-up failures, driving design corrective actions.
- Design Python-based automation to improve lab efficiency and partner with architecture teams to implement end-to-end manufacturing test solutions.
- Influence next-generation product design via validation feedback and support production teams in developing ATE/SLT screens to reduce Defective Parts per Million (DPPM).
