{"title": "Signal Integrity and Power Integrity Engineer, Pixel Watches", "level": "Early", "location": "Mountain View, CA, USA", "description": "Be part of a diverse 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 Signal Integrity and Power Integrity (SIPI) Engineer, you will be responsible for the SIPI analysis and design of next-generation Pixel watches. You will be involved in each stage of the product development from the prototype to the mass production including PCB/FPCB stackup, design rules, pre-layout and post-layout simulations for electrical interfaces, critical signals, and power delivery networks (PDNs). You will closely work with cross-functional teams to solve any SIPI related design issues and provide solutions. Simulation and measurement correlation is the key to maintaining the simulation confidence level in product development. In this role, you will be responsible for the correlation between simulation and lab measurement including the characteristics of passive channels, interface timing and PDN impedances, which require you to be familiar with lab equipment including VNA, TDR, and Oscilloscope, etc. Google's mission is to organize the world's information and make it universally accessible and useful. Our Devices & Services team combines the best of Google AI, Software, and Hardware to create radically helpful experiences for users. We research, design, and develop new technologies and hardware to make our user's interaction with computing faster, seamless, and more powerful. Whether finding new ways to capture and sense the world around us, advancing form factors, or improving interaction methods, the Devices & Services team is making people's lives better through technology.", "salary": "$102,000-$150,000 + bonus + equity + benefits", "key_qualifications": "Bachelor's degree in Electrical Engineering, a related field, or equivalent practical experience.
