Job description

Strong likelihood of extension

We're looking for a Senior UX Designer to help shape the future of AI-powered experiences within a large, regulated organisation.

This is not a traditional UX role focused on design systems or incremental product improvements. Instead, you'll be helping define how emerging AI capabilities are experienced by customers, creating intuitive interaction patterns, conversational journeys and new ways for users to engage with AI within a consumer mobile app.

You'll thrive in this role if you enjoy working in ambiguity, exploring new problem spaces and helping shape products where established patterns don't yet exist.

What You’ll Be Doing

• Defining end-to-end AI-powered customer experiences within a consumer mobile application
• Designing intuitive interaction patterns for conversational and AI-driven experiences
• Exploring how customers discover, access and move between multiple AI capabilities and agents
• Creating prototypes and concepts to test ideas, validate assumptions and influence product direction
• Translating complex propositions into simple, intuitive user experiences
• Working closely with Product, Engineering, Research and Design stakeholders
• Balancing long-term experience vision with practical, deliverable UX solutions
• Helping establish new interaction models for emerging technologies
• Strong UX Design experience within consumer-facing mobile applications
• Outstanding interaction design skills with a focus on user behaviour, journeys and experience architecture
• Experience designing complex products or services from discovery through to delivery
• Proven ability to work in ambiguous environments and define experiences where requirements are still emerging
• Strong systems-thinking mindset, connecting multiple journeys, touchpoints and capabilities into a cohesive customer experience
• Excellent prototyping skills using tools such as Figma
• Ability to move between strategic experience thinking and detailed interaction design

Highly Desirable

• Conversational UX or chat-based experiences
• AI Assistant, GenAI or intelligent product experience
• Agentic AI or multi-agent experience
• Experience designing new interaction patterns and behaviours
• Exposure to regulated environments such as Financial Services, Insurance, Healthcare or Government

We’re Particularly Interested In People Who Have

• Designed mobile-first consumer experiences
• Worked on innovative, zero-to-one products
• Shaped how users interact with AI-powered capabilities
• Defined behaviours and interactions, not just user journeys and processes
• Used research and insight to create structured solutions to complex problems
• Created and tested concepts where no established design pattern existed

If you're passionate about emerging technologies and excited by the challenge of defining the next generation of AI-powered customer experiences, we'd love to hear from you.
