Responsibilities

• Lead end-to-end interaction design on client projects, from initial concepts and user flows through to high-fidelity prototypes and design specifications
• Take ownership of complex design challenges, applying user-centered design principles, behavioural psychology, and established UX heuristics to solve problems strategically
• Create sophisticated interactive prototypes using Figma, ProtoPie, Principle, or Framer to demonstrate interaction models, micro-interactions, and multi-step user journeys
• Design and document scalable design systems, interaction patterns, and component libraries that maintain consistency across large-scale digital products
• Collaborate closely with researchers to translate user insights and testing findings into actionable design improvements and strategic recommendations
• 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

Requirements

• 3–5 years of experience in interaction design, UX design, or product design within an agency, consultancy, or product team environment
• A strong portfolio demonstrating end-to-end project ownership—showing strategic thinking, interaction craft, and measurable impact across diverse projects
• Expert-level proficiency in Figma with demonstrated ability to build complex, component-based design systems and interactive prototypes
• Deep understanding of interaction design principles, design psychology, and usability heuristics with the ability to apply them strategically across different contexts
• Proven experience designing responsive, multi-device experiences with sophisticated interaction patterns that adapt intelligently across breakpoints
• Strong knowledge of accessibility standards (WCAG AA) and practical experience designing inclusive interactions for diverse user needs
• Experience working directly with development teams, understanding technical constraints, and producing clear, implementable design specifications
• Excellent stakeholder management and presentation skills—comfortable leading workshops, presenting to senior clients, and navigating feedback diplomatically
• Ability to work autonomously, manage multiple projects simultaneously, and prioritize effectively in a fast-paced agency environment
• Experience mentoring or supporting junior designers
• Experience leading design on projects in regulated or complex industries (healthcare, life sciences, financial services, public sector) where compliance and trust are critical
• Advanced prototyping skills using ProtoPie, Principle, Framer, or After Effects to demonstrate sophisticated interaction behaviours and animated transitions
• Understanding of front-end development (HTML/CSS/JavaScript fundamentals) to inform feasibility and collaborate more effectively with technical teams
• Experience designing AI-enhanced interfaces, intelligent search systems, personalization engines, or adaptive user experiences
• Knowledge of analytics and user testing tools (Hotjar, Maze, UserTesting) and experience using quantitative and qualitative data to validate design decisions
