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.

At YouTube, we believe that everyone deserves to have a voice, and that the world is a better place when we listen, share, and build community through our stories. We work together to give everyone the power to share their story, explore what they love, and connect with one another in the process. Working at the intersection of cutting-edge technology and boundless creativity, we move at the speed of culture with a shared goal to show people the world. We explore new ideas, solve real problems, and have fun — and we do it all together.

Responsibilities

• Design, implement, and deploy improvements to machine learning models (e.g., Product Detection, Video Classification, Timestamp Detection) to enhance accuracy and coverage.
• Build and maintain pipelines for training data curation and model evaluation. Ensure the models learn from shopping signals by managing quality datasets, while developing evaluation frameworks to measure performance and analyze cases.
• Collaborate with cross-functional teams to ensure new model signals are adopted by downstream systems (e.g., Recommendation system, Creator team, etc).
• Contribute to the back-end infrastructure (e.g., orchestration, storage, serving, freshness) to ensure models run efficiently at YouTube scale, impacting system latency and cost.
• Implement solutions in one or more specialized ML areas, utilize ML infrastructure, and contribute to model optimization and data processing.
