Interaction Design Lead

IDEO London is seeking an Interaction Design Lead with a passion for creating human-centred experiences and helping teams do their best work. You'll lead and co-lead multidisciplinary teams, stay close to the craft, and guide clients from complex questions to tangible products and services. Your work will span digital and physical experiences, including new ways for people to interact with AI.

We're a global design consultancy where curiosity, empathy, and solving complex challenges drive us. For over 40 years, we've partnered with clients to innovate in healthcare, mobility, education, retail, and beyond. Here, every challenge is a chance to grow, connect, and create impact.

Interaction Design is at the heart of creating meaningful human-centred experiences that meet people's needs and help businesses move forward. As an Interaction Design Lead, you'll bring together craft, creative direction and project leadership to help teams turn strategy into experiences people can use. As AI becomes part of everyday products and services, you'll help us explore how people understand, trust and stay in control of systems that can act on their behalf.

• Lead and co-lead multidisciplinary project teams from research and framing through design, prototyping and delivery, balancing people's needs, client goals and technical possibilities
• Set a clear design direction and stay hands-on with journeys, flows, interfaces and interaction details, connecting individual touchpoints to a coherent product or service experience
• Build and guide prototypes at the right fidelity to answer the team's questions, using Figma, code and AI-assisted tools to make ideas tangible early and test them with people
• Partner with researchers and technologists to plan experiments, test usability and accessibility, and use qualitative feedback and product data to refine designs and assess their impact
• Explore conversational and agentic UX: design how people express intent, approve actions, understand what an AI system is doing, redirect it and recover when things go wrong
• Own project plans, resource needs and delivery milestones; brief and delegate work clearly, spot obstacles early, and help the team navigate ambiguity while maintaining creative quality

• The ability to scope, brief and delegate design work, manage timelines and resources, and empower a small to medium team to take ownership of different parts of a project
• A keen eye for visual hierarchy, responsive interfaces, motion and micro-interactions, and the ability to critique work and offer clear, actionable feedback
• Strong prototyping skills in Figma or comparable tools, and confidence experimenting with AI-assisted ideation and prototyping while checking outputs and making your own design judgements
• A commitment to accessibility and inclusive design, and thoughtful judgement about privacy, bias and people's agency when designing with AI
