Senior Product Designer in London

The Global Performics Team strategizes and provides digital activation services for global advertisers in over 57+ markets around the world with the aim to deliver the optimal outcome. Our Performance Centre of Excellence drives performance solutions across several channels including social, search, programmatic, commerce and affiliates.

We are seeking a Senior UX/UI Designer to join our team and lead AI-enabled UX/UI design for our cutting-edge performance marketing platform. As the Senior UX/UI Designer, you will pioneer AI-to-UI (A2UI) design paradigms, leveraging Figma MCP (Model Context Protocol) integrations and generative AI tools to rapidly translate complex data insights and AI-driven recommendations into intuitive, adaptive interfaces that empower marketers to make informed decisions.

Your role will involve designing AI-assisted workflows, building intelligent component systems that respond to real-time data, and ensuring our platform delivers exceptional usability through AI-augmented design processes. The ideal candidate should have extensive experience in designing AI-native applications, hands-on expertise with Figma MCP server integrations and A2UI pipelines, a deep understanding of user-centred design principles, and the ability to bridge the gap between large language models and production-ready UI.

• Lead end-to-end AI-enabled UX/UI design processes for our AI-based performance marketing platform, integrating A2UI pipelines and Figma MCP servers into the design workflow from user research and information architecture to AI-accelerated prototyping and usability testing.
• Design AI-adaptive interfaces and workflows using A2UI frameworks that dynamically render AI-generated content and make complex performance data easily digestible for marketers of varying technical expertise.
• Create AI-ready design systems and intelligent component libraries optimized for Figma MCP integrations, ensuring consistent user experiences across the platform while enabling AI-driven design token management and scalability for future features.
• Collaborate with product managers, engineers, data scientists, and AI/ML teams to translate LLM outputs and AI model capabilities into production-ready UI components through A2UI design patterns and MCP-connected workflows.
• Conduct user research and usability testing to validate design decisions and continuously improve the platform's user experience based on real user feedback.
• Develop AI-assisted wireframes, prototypes, and high-fidelity designs using Figma with MCP server connections, leveraging AI-powered design generation while ensuring accessibility standards and responsive design principles.
• Architect AI-to-UI rendering pipelines and streamline data visualization interfaces that surface AI-generated actionable insights from performance marketing campaigns in real time.

• Relevant experience in UX/UI design - ideally focused on complex web applications, data platforms, or SaaS products.
• Proven experience designing AI-native interfaces and A2UI systems where LLM outputs are rendered as dynamic UI, with demonstrated ability to simplify complex AI-driven concepts for end users.
• Expertise in AI-augmented design tools with advanced Figma proficiency including MCP server integrations, AI plugins, and Dev Mode; experience with prototyping tools like Framer, Principle, or AI-native tools such as Galileo AI or Uizard.
• Strong foundation in user research methodologies including user interviews, usability testing, A/B testing, and analytics interpretation.
• Deep understanding of information architecture and interaction design principles for complex data-driven applications.
• Experience with AI-connected design systems and component libraries that support MCP-driven design token synchronization, including documentation and maintenance best practices.
• Knowledge of front-end technologies and AI integration patterns (HTML, CSS, JavaScript, React basics) including understanding of how LLM APIs render into frontend components via A2UI patterns.
• Portfolio showcasing AI-enabled UX/UI projects demonstrating A2UI implementations, AI-assisted design workflows, and measurable impact on user experience.
• Excellent communication and presentation skills with ability to articulate design decisions to stakeholders at all levels.

• Experience in marketing technology (MarTech) or advertising technology (AdTech) with understanding of performance marketing workflows and KPIs.
• Familiarity with data visualization principles and experience designing dashboards, reporting interfaces, or analytics platforms.
• Hands‑on experience with Figma MCP server setup, configuration, and plugin development for AI-connected design workflows.
• Experience building A2UI prototypes that translate structured AI/LLM outputs (JSON, streaming responses) into interactive UI components.
• Familiarity with Model Context Protocol (MCP) architecture and experience connecting AI tools to design environments via MCP servers.
• Understanding of generative AI design tools, prompt-to‑UI workflows, and experience with AI copilot interfaces or conversational UI design patterns.
• Bachelor’s degree in UX/UI Design, Interaction Design, Human‑Computer Interaction, or related field (or equivalent practical experience).
