Experience Level: Mid-Senior to Senior (5-10 years)

Remote Status: On-site

🚀 Role Summary

• Design and evolve the shared chat design system, encompassing foundations, components, and composed patterns across Figma, web, iOS, and Android for the AI-native interaction layer at Wise.

• Shape the end-to-end AI assistant experience, including entry points, conversation patterns, streaming states, and structured UI interactions, ensuring consistency across all platforms.

• Collaborate closely with engineering and content design to define architectural contracts for the assistant's capabilities and UI rendering.

• Partner with product teams to integrate the assistant into their domains, reviewing UI proposals and ensuring adherence to the shared design system.

• Prototype interactions in code to validate AI-specific user experience details such as streaming, interruption, error recovery, and latency states.

📝 Enhancement Note: This role is positioned as a Staff Product Designer, indicating a senior individual contributor role with significant influence over the technical architecture and user experience of a core platform feature. The focus on an "AI-native interaction layer" and "design system" suggests a need for deep expertise in both user-centered design principles and the technical intricacies of building scalable, cross-platform components. The emphasis on "design at the level of architecture" highlights the strategic importance of this role beyond traditional UI design.

📈 Primary Responsibilities

• Own the design and continuous evolution of the Wise Assistant's shared chat design system, ensuring atomic precision (tokens, variants, states) and system-level coherence.

• Design the full spectrum of AI assistant interactions, from initial user entry points to complex conversational flows and integrated UI elements.

• Define and maintain design standards for component states, accessibility, micro-interactions, and overall interaction quality across all supported platforms.

• Collaborate with engineering teams to establish clear component APIs and ensure seamless implementation of design specifications.

• Act as a design authority for partner product teams, guiding their integration of assistant experiences and preventing system fragmentation.

• Develop high-fidelity prototypes, potentially in code, to rigorously test and validate AI-specific interaction patterns and user flows.

• Uphold and elevate the overall product design craft, focusing on usability, intuitiveness, and the seamless integration of AI capabilities into the user journey.

📝 Enhancement Note: The responsibilities emphasize a blend of strategic system design and tactical execution. The need to "define the contracts that govern what the assistant can say and how the design system renders it" points to a role that bridges design and technical specification, requiring a deep understanding of both user needs and system capabilities. The emphasis on "prototyping in code" suggests a hands-on approach and a requirement for technical fluency beyond typical design tools.
