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.
We are the Recommendations Machine Learning (RecML) team in Core ML's Applied ML organization. Our mission is to accelerate product innovations through ML for recommendations and user modeling. We collaborate with various Alphabet product areas and partner with them to help accelerate product innovations through applied research in recommendations and user modeling. We also generalize successful innovations into standardized, maintainable, and production-grade solutions for use by other teams and products.
The AI and Infrastructure team is redefining what’s possible. We empower Google customers with breakthrough capabilities and insights by delivering AI and Infrastructure at unparalleled scale, efficiency, reliability and velocity. Our customers include Googlers, Google Cloud customers, and billions of Google users worldwide.

Responsibilities
- Define and execute the applied research roadmap for the Large User Model ecosystem, balancing immediate customer needs with long-term technical evolution to scale foundational models across high-traffic surfaces.
- Support initiatives with product leadership to translate complex business goals into technical model formulations, delivering step-function improvements in user engagement and business metrics while optimizing for latency and performance trade-offs.
- Optimize model performance by researching and implementing adaptation techniques (transfer learning/domain adaptation) that balances high-quality output with strict inference latency requirements for production environments.
- Drive architectural improvements by establishing a strategic feedback loop with pre-training teams, utilizing downstream performance analysis to influence data curation, model architecture, and novel evaluation metrics for engagement-specific needs.
- Design and productionize fine-tuning pipelines that translate general-purpose state-of-the-art (SoTA) Foundation User Models into effective, domain-specific recommendation engines.
