We're looking for a Mid-Weight UX Designer to take creative ownership of interaction design across high-impact client projects. You'll be the design lead on key work streams, shaping user experiences for enterprise platforms, complex B2B services, healthcare applications, and consumer-facing digital products that demand both strategic thinking and exceptional craft.

This is a role for a confident designer who can work independently, mentor junior team members, and bridge the gap between strategy and execution. You'll lead design thinking from concept through to delivery, collaborating with UX researchers, visual designers, developers, and client stakeholders to create interaction designs that solve real business problems while elevating user experience standards.

You won't just be executing briefs, you'll be helping to define them, challenging assumptions, and using your experience to guide clients toward smarter, more effective solutions.

• Work with development teams throughout build phases, reviewing implementations, problem-solving technical constraints, and ensuring interaction fidelity
• Lead client-facing design presentations and workshops, articulating design rationale, defending creative decisions, and facilitating productive feedback sessions
• Mentor junior designers, providing constructive critique, sharing best practices, and helping to raise the overall craft quality across the team
• Champion accessibility and inclusive design, conducting audits and embedding WCAG standards into every stage of the design process
• Contribute to new business pitches and proposals, helping to shape project approaches and demonstrate our design capabilities
• Stay ahead of industry trends, emerging interaction patterns, AI-enhanced interfaces, and new tools—bringing thought leadership to internal discussions and client work
• Support the evolution of our design practice, contributing to internal processes, toolkits, and knowledge-sharing initiatives
