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.

Grow the YouTube Ads business by understanding user interest and recommend ads

that are aligned with user interest. The YouTube Ads User Models are a suite of

large-scale AI systems designed to model users commercial interests by

leveraging Google-wide data sources approved for advertising purposes. Designed

for multi-task learning across various surfaces, these models are applied to

numerous downstream tasks, including retrieval, user action prediction, rich

user generation, and knowledge distillation for training more compact models.

Work with a team of software engineers, ML engineers, and Data Scientists to

understand long-term user interest from a source of information from across the

company. Build a large recommendation system using LLMs, Sequence Modeling,

GNNs, and other similar algorithms. Predict likelihood of user interest in a

particular ad.

Google Ads is at the forefront of AI innovation, applying cutting-edge machine

learning and Generative AI models like Gemini to power a multi-billion dollar

global business.

Our work directly impacts billions of users by protecting users from harm,

improving ad quality, and optimizing campaigns for advertiser

return-on-investment. We foster a culture of deep collaboration, partnering

closely with teams like Google Research and DeepMind to solve complex

challenges. Join us to work on state-of-the-art AI, take on problems at an

unparalleled scale, and build the next generation of advertising technology.

Individual pay is determined by factors including job-related skills,

experience, and relevant education or training.
