About The Job

As a Firmware Engineer on the Layer 1 Radio Frequency (RF) Software team, you’ll focus on the RF configuration and driver, including the development, integration, customization, and performance enhancement of modem RF on Android devices, working closely with Pixel Software/Hardware teams, original equipment manufacturers (OEM) and vendors.

In this role, you’ll be the point of contact for all debugging, analyzing, and fixing modem RF issues from bring-up, factory, certification (e.g., GCF, PTCRB, IOT), field testing and customers. You’ll also be responsible for validating the function and performance of RF features. In this team, you’ll have the opportunity to expand your domain knowledge vertically (i.e. from antenna/RF to protocols) and understand the modem from the viewpoint of the system. You will also be encouraged to propose your innovative and practical ideas to optimize the RF performance.

Making the world’s information universally accessible and useful doesn’t stop at the desktop. The Mobile team builds tools to get you the information you need no matter where you are. Android has become the world’s most popular mobile ecosystem, powering billions of devices, from smartphones to tablets, watches to TVs and everything in between. Whether adding to the core Android experience, forging new markets for digital content, creating immersive and portable versions of our products or managing relationships with a global community of developers, the Mobile team is giving you Google on the go.

Responsibilities

• Develop RF configuration and driver, and validate the function and performance of modem RF features.
• Debug, analyze, and fix modem RF issues from bring-up, factory (e.g., SMT, FATP), certification (e.g., GCF/PTCRB/IOT), field testing, and customers.
• Work with Software/Hardware teams to deliver high-quality Pixel modem.
• Work with RF Software RFFE control driver (e.g., MIPI-based, GPIO-based) development.
• Design review with RF hardware in terms of front-end schematic, block diagram for standalone/CA/ENDC cases.
