The Opportunity

We're working with a major UK financial services organisation that is investing heavily in next-generation Conversational AI. This role sits within a brand-new, greenfield proposition, focused on evolving traditional chatbots into agentic AI experiences that can reason, act, and support customers in more meaningful ways.

• Design and evolve natural, human-like back-and-forth conversational interactions
• Work across discovery, journey mapping, and problem framing to deeply understand user needs
• Help establish new design processes and ways of working in an environment with no existing blueprint
• Collaborate closely with designers, product, and engineering teams
• Take ownership of design decisions, clearly articulate the rationale, and influence direction across the team

What We're Looking For

• Strong, hands-on experience in Conversational AI (essential)
• Background in content design, with a clear move into conversation design
• Deep understanding of human conversation fundamentals and how they translate into machine-led interactions
• Experience designing conversational interfaces using large language models (LLMs)
• Comfortable working in fast-paced, experimental environments with evolving requirements
• Confident senior designer who can lead through ambiguity and bring others along
• Curious, engaged, and ideally active in design communities, bringing external thinking into the organisation
