About The Position

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 manage information at a 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.In this role, you will design the new intelligence layer of the Search’s growth ecosystem with a new long-term life-cycle model.In Google Search, we're reimagining what it means to search for information – any way and anywhere. To do that, we need to solve engineering issues and expand our infrastructure, while maintaining a universally accessible and useful experience that people around the world rely on. In joining the Search team, you'll have an opportunity to make an impact on billions of people globally.

Requirements

Responsibilities

Design and deploy advanced models (e.g., Contextual Bandits, Transformers, Sequence Modeling) to optimize promo inventory by leveraging on multi-headed objective functions that balance growth goals against user annoyance costs.
Build systems for training, deploying, and monitoring models. Scale our ML training infrastructure with TensorFlow and JAX.
Optimize model architectures for high-throughput, low-latency environments, ensuring the ML models never compromise core Search performance.
Drive model performance by testing and ingesting novel signals (including multi-modal embeddings and Large Language Model (LLM)-generated user profiles), designing and executing A/B tests to measure ML-driven feature effectiveness, and iterating quickly based on findings.
Build the engine that manages and generates hyper-personalized, multi-turn LLM prompts within the new AI Mode infrastructure.
