Surfaces Model UX Designer, GeminiApp, DeepMind

Minimum qualifications:

• Bachelor's degree in Cognitive Science, Human-Computer Interaction (HCI), Linguistics, a related field, or equivalent practical experience.
• 6 years of experience in conversation design, content design, with equivalent experience designing for conversational AI/LLMs.
• Include a portfolio, website, or any other relevant link to your work in your resume (providing a viewable link or access instructions).

Preferred qualifications:

• Experience in interaction design, particularly managing mixed tactile/voice entry points and mid-conversation modality switching.
• Experience in guiding cross-functional teams through ideation, validation, and iteration processes, transforming abstract ideas into shippable, user-centered model behavior.
• Experience in vibe-coding and developing AI-powered prototypes.
• Familiarity with behavioral data and strong capability to utilize user signals and life-cycle data to create data-driven designs, while being equally capable of moving forward in the absence of data.
• Excellent communication and collaboration skills with the ability to articulate positions, and challenge cross-functional partners with rigorous model UX principles.

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 Deep Mind, 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.

We are pushing the boundaries across multiple domains. Our global teams offer various learning opportunities and varied career pathways for those driven to achieve exceptional results through collective effort.
