The role requires 2 days per week on site in London.

Qualifications

• Use a range of research, testing and validation techniques to shape concepts and improve designs from the earliest stages.
• Work alongside researchers and wider product teams to turn customer feedback, research findings and behavioural insight into clear design opportunities.
• Test assumptions and hypotheses throughout the design process, ensuring decisions are grounded in evidence rather than opinion.
• Combine qualitative research with product data and customer behaviour to understand pain points and identify areas for improvement.
• Own the design of end-to-end digital experiences, considering the complete customer journey rather than individual screens or features.
• Translate complex requirements into clear user journeys, information architecture, wireframes, interaction models and user flows.
• Take ideas from early concepts and sketches through to well-defined, intuitive digital experiences.
• Design with the wider ecosystem in mind, understanding how individual journeys connect across different products, services and digital channels.
• Work closely with Product, Research and Engineering teams to balance user needs, commercial priorities and technical feasibility.
• Use research insights, behavioural trends and product performance data to guide design decisions and prioritisation.
• Partner with Product Managers and Product Owners to identify opportunities, influence product direction and establish measures of success.
• Ensure experiences meet appropriate accessibility, usability and inclusive design standards.
• Create high-fidelity interface designs and interactive prototypes in Figma, turning UX concepts into polished digital experiences.
• Use prototypes to explore different approaches, communicate interaction behaviour and test ideas before development.
• Design responsive experiences for web and mobile, considering different screen sizes, devices, platforms and accessibility needs.
• Refine designs through an iterative process, incorporating user testing, stakeholder input and feedback from development teams.
• Create and apply reusable components, interaction patterns and design standards that improve consistency across products.
• Contribute to the continued development and adoption of design systems and component libraries.
• Work closely with developers to make sure designs are practical to implement and that the finished product reflects the intended experience.
• Champion strong standards across visual design, interaction design, accessibility and overall design quality.
• Work as part of a cross-functional product team, partnering closely with Product, Engineering, Research and other Design specialists.
• Clearly communicate design thinking and rationale, using research, customer insight and data to support recommendations.
• Facilitate collaborative sessions and design discussions to explore problems, generate ideas and build alignment.
• Contribute throughout the product lifecycle, from discovery and problem definition through to design, validation and delivery.
• Help create a consistent customer experience across products by championing shared design principles, patterns and ways of working.
