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 looking for a senior staff engineer to join the AI Data organization. In this role, you will be responsible for technical leadership for several critical areas of collecting high-quality data for GenAI workflows.

This role focuses on design and development of systems for catering to different stages of genAI data - pre-training, SFT (Supervised Fine-Tuning)/RLHF (Reinforcement Learning from Human Feedback), for the overall data flywheel. The focus will be in innovating various ways to quickly generate high-quality data for frontier use-cases including Agents, RL, etc.

This role requires working closely with GDM, Research and other infrastructure teams, in addition to cross functional collaboration with different product teams.
