Lead UI/UX Designer

We’re rethinking homes for how people really live, and we’re looking for a Lead UI/UX Designer to join our Technology team to help shape intuitive, high-performing experiences for our customers and teams.

Success in this role means improving Castlery’s customer journey, from discovery to post-purchase, while creating better tools for our internal teams. You’ll also evolve our design system, improve collaboration with Engineering, mentor designers and use AI tools to help the team work smarter.

What you'll be doing:

• Lead the design of customer experiences across web and mobile, from early exploration through to launch and iteration.
• Shape key moments across discovery, product pages, cart, checkout and post-purchase.
• Design internal tools that make life easier for our Operations, Customer Experience, Retail and Fulfilment teams.
• Turn broad or ambiguous problems into clear design opportunities, practical priorities and experiences that can ship.
• Use customer insight, product data and experimentation to inform your decisions - without letting the numbers replace good design judgement.
• Work closely with Product, Engineering, Data, Marketing and Supply Chain to balance customer needs, commercial goals and technical realities.
• Evolve our design system so it is coherent, useful and genuinely adopted, rather than becoming a library that nobody uses.
• Stay close to the details: flows, prototypes, typography, interaction, responsive behavior, accessibility and the final build.
• Lead critiques and design reviews that make the work better without making the room defensive.
• Mentor designers through the work, giving them context, honest feedback and the space to develop their own judgement.
• Help set a clear design direction while creating an environment where strong ideas can come from anyone.
• Explore how AI-assisted tools can improve research, prototyping and delivery, while knowing when human judgement matters more.

What you need to succeed:

• 5-10 years of experience in product, UX or UI design, with a proven track record of delivering digital products across web and mobile.
• A strong portfolio demonstrating your design process, individual contribution and the impact of your work.
• Strong visual and interaction design skills, including typography, layout, imagery, motion and responsive design.
• Experience designing products that support business and user outcomes, such as conversion, revenue, efficiency or error reduction.
• Experience with user research, experimentation and A/B testing.
• Advanced proficiency in Figma and experience building or managing design systems.
• Experience mentoring designers, providing constructive feedback and leading design reviews.
• Strong commercial judgement and the ability to balance design quality, business priorities and delivery timelines.
• Working knowledge of accessibility standards and inclusive design practices.
