At Meta, we are building Personal Superintelligence to empower every individual with greater agency. The RealTime AI team within MSL is seeking a Principal Product Designer to lead the user experience of embodied, AI-powered agents. In this role, you will operate at the intersection of high-end craft and machine learning research. You will be responsible for translating complex AI capabilities into intuitive, high-fidelity human experiences, ensuring our "RealTime" vision is both technically feasible and resonant with users.
Job Responsibility:
Drive the Interaction Framework for Embodied AI: Establish and evolve the design patterns for real-time AI
define how AI surfaces across mobile, glasses, and future form factors, balancing proactive assistance with user control
Execute Multimodal Design Strategy: Lead the development of scalable interaction systems that integrate voice, vision, and gesture
design the feedback loops that make AI feel responsive, low-latency, and contextually aware
Define Behavioral UI: Define the "personality" and pacing of AI interactions
ensure these agents feel human-centric, reliable, and helpful rather than intrusive
Strategic XFN Partnership: Partner with Product, ML Research, and Engineering to influence model behavior
use design as a lens to help the team prioritize data collection and model tuning based on UX needs (e.g., latency vs. accuracy)
Bridge Research and Product: Drive high-velocity prototyping for "zero-to-one" AI features
translate raw research (like live world-understanding) into production-ready product visions for the Family of Apps and Reality Labs
Design Leadership & Mentorship: Serve as a pillar of the MSL design community
unblock complex design challenges for the team, mentor L5/L6 designers, and raise the collective "quality bar" for AI design within the organization
Requirements:
8-10+ years of experience in product design or creative direction, with a portfolio showcasing the experience solving complex, systems-level problems
Demonstrated experience designing for non-deterministic systems
understanding of prompting, model constraints, and how to design for "graceful failure" in AI
Proven track record of navigating extreme ambiguity and driving projects from concept to execution with minimal guidance
Proficiency in Figma and a high degree of experience with AI-assisted coding or prototyping tools (e.g., Cursor, Framer, or similar) to demonstrate motion and interaction
A history of using research and signals to balance technical capabilities with human wellbeing and user agency
Nice to have:
Conversational UX Experience: Specific experience building digital assistants, chatbots, or virtual beings
Cross-Pillar Impact: Experience driving design standards or initiatives that have been adopted across multiple product teams or organizations
High-Velocity Shipping: Experience operating in "startup-style" environments within larger companies, shipping quickly under technical constraints
Persuasive Communication: Experience representing design at the leadership level (VP/Director), articulating the "why" behind complex design bets
