ABOUT THE JOB:

Google's software engineers develop the next-generation technologies that change

how billions of users connect, explore, and interact with information and one

another. Our products need to handle information at massive scale, and extend

well beyond web search. We're looking for engineers who bring fresh ideas from

all areas, including information retrieval, distributed computing, large-scale

system design, networking and data storage, security, artificial intelligence,

natural language processing, UI design and mobile; the list goes on and is

growing every day. As a software engineer, you will work on a specific project

critical to Google’s needs with opportunities to switch teams and projects as

you and our fast-paced business grow and evolve. We need our engineers to be

versatile, display leadership qualities and be enthusiastic to take on new

problems across the full-stack as we continue to push technology forward.

Our team’s mission is to build next generation of USB (Universal Serial Bus)

connectivity and charging for Pixels and enable end users to use Google’s

first-party and third-party chargers and accessories, USB-C connectivity with

host PCs while ensuring USB-C port health and reliability. Our team owns the

software stack needed to provide seamless experience while using Type-C USB

ports in Pixel phones and tablets.This is a unique opportunity to experience

full stack Android system software development.

In this role, you will direct code across different parts of Android stack right

from Linux kernel, HAL, Android system server to fiddling with hardware in

bootloader and directly influencing silicon architecture. You will be working

and collaborating across areas and through every stage of development from

schematic reviews to user experience.

The Platforms and Devices team encompasses Google's various computing software

platforms across environments (desktop, mobile, applications), as well as our

first party devices and services that combine the best of Google AI, software,

and hardware. Teams across this area research, design, and develop new
