Director, Ux, Search Model Behavior

Google Google · Big Tech · San Francisco, CA +2

Director of UX for Model Behavior in Google Search, focusing on shaping user interactions with conversational agents and generative features like AI Overviews and AI Mode. This role involves defining strategy for model persona, conversational architecture, and interaction principles, translating user needs into technical signals for helpful, safe, and aligned AI experiences. Responsibilities include embedding UX into the ML lifecycle, influencing technical architecture via SFT and RLHF, owning AI voice/tone policies, developing constitutional guidelines, establishing evaluation frameworks for quality, hallucination reduction, and bias mitigation, and leading a multidisciplinary team.

What you'd actually do

  1. Partner directly with ML/Engineering leadership to embed UX principles into the model development lifecycle. Influence technical architecture by translating UX research into actionable protocols for model training, system prompting, Supervised Fine-Tuning (SFT), and Reinforcement Learning from Human Feedback (RLHF).
  2. Own/scale overarching voice, tone, and behavioral policies of Search AI. Develop constitutional guidelines and conversational frameworks that dictate how the model responds to complex, ambiguous, or sensitive queries.
  3. Define what “great” looks like across all AI surfaces. Establish rigorous qualitative rubrics and human-evaluation frameworks to continuously measure model output quality, reduce hallucinations, and mitigate bias.
  4. Lead a multidisciplinary team of UI Designers, UX Researchers, Model Behavior Specialists, and Program Managers. Foster a collaborative culture that operates at the intersection of design, linguistics, artificial intelligence.

Skills

Required

  • 15 years of experience managing multi-disciplinary design and technical interaction teams.
  • Experience managing teams of integrated content specialists.
  • Experience in RLHF, model fine-tuning, and developing evaluation frameworks (e.g., SxS testing).

Nice to have

  • Bachelor’s degree in English, Journalism, Media, Communications, HCI, or related field, or equivalent practical experience.
  • Experience fostering divergent design thinking, shepherding radical ideas that can truly evolve products.
  • Experience leading the model behavior vision and execution of large-scale products with a focus on localization, usability, and accessibility best practices for global AI platforms.
  • Excellent communication and scaled leadership experience, with the ability to lead model behavior in an ambiguous space, and work to define methods/approaches.
  • Curiosity and excellent technical aptitude to understand the global product ecosystem and influence cross-functional stakeholders across Google and drive scalable model design solutions.
  • Track record of building/scaling multidisciplinary teams within highly matrixed environments.
