About the Job

In this role, you will shape the evolution of Gemini’s mobile experience on Floaty, turning it into a seamless, contextual, and highly listenable assistant. As a key member of the Gemini App Model UX team, you will collaborate with product managers, engineers, and research scientists to solve unique multimodal and voice issues for a highly visible representative experience of Gemini. You will work directly with Google’s advanced AI models to build real-world solutions that refine talk tracks, optimize dynamic responses, and manage complex multi-modal context switching. Your work will ensure that every model response feels intuitive, glanceable, and reliable, driving meaningful engagement and quality improvements for millions of users on-the-go.

Artificial intelligence will be one of humanity’s most transformative inventions. At Google DeepMind, we are a pioneering AI lab with exceptional interdisciplinary teams focused on advancing AI development to solve complex global challenges and accelerate high-quality product innovation for billions of users. We use our technologies for widespread public benefit and scientific discovery, ensuring safety and ethics are always our highest priority.

Responsibilities

• Specify the ideal conversational structures, query categorization logic, and underlying interaction patterns that bring voice, text, and multimodal entry points to life.
• Implement advanced system instructions (SIs) that optimize dynamic responses based on user signals and device capabilities.
• Apply systems thinking to deliver flexible solutions that scale across a range of devices.  
• Initiate qualitative assessments of model performance, establishing principle-based rubrics to drive continuous quality hillclimbing across core user journeys (CUJs).
• Partner with AI product designers to craft leading-edge multimodal solutions, ensuring model responses, device signals, and screen relevancy work in concert to deliver cohesive, glanceable experiences.

Qualifications

Minimum qualifications:

• Bachelor's degree in Cognitive Science, Human-Computer Interaction (HCI), Linguistics, a related field, or equivalent practical experience.
