MSL Product Designer

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 experience into intuitive, high-fidelity human experiences, ensuring our "RealTime" vision is both technically feasible and resonant with users. **Responsibilities** Drive the Interaction Framework for Embodied AI: Establish and evolve the design patterns for real-time AI. You will 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. You will design the feedback loops that make AI feel responsive, low-latency, and contextually aware \* Define Behavioral UI: Beyond visual components, you will define the "personality" and pacing of AI interactions. You’ll 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. You will 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. You will 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. You will unblock complex design challenges for the team, mentor L5/L6 designers, and raise the collective "quality bar" for AI design within the organization **Qualifications** Advanced Craft & Systems Thinking: 10+ years of experience in product design or creative direction, with a portfolio showcasing the experience solving complex, systems-level problems \* AI/ML Fluency: Demonstrated experience designing for non-deterministic systems. You understand prompting, model constraints, and how to design for "graceful failure" in AI \* Strategic Autonomy: Proven track record of navigating extreme ambiguity and driving projects from concept to execution with minimal guidance \* Prototyping: 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 \* Human-Centric Approach: A history of using research and signals to balance technical capabilities with human wellbeing and user agency Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements) \* Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews) \* Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies \* 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 \* Demonstrated experience integrating AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
