Ux Design jobs in United Kingdom

You’re a problem-solver, not just a pixel-pusher. You obsess over user flows, not just colours. And you’re looking for a blank canvas—where your design thinking shapes not only the interface but the entire product experience.

If you’ve led UX design in early-stage startups or thrive in ambiguity with a founder who has built and exited a SaaS business, this might be your next adventure.

Our client—a Silicon Valley-backed AI startup—is reshaping how product teams collaborate, discover, and solve. With a product already near release and strong internal feedback loops, the challenge now is levelling up from “usable” to “unmissable.”

They’re seeking a Founding UX Designer to elevate the product from functional to lovable. This is not a UI facelift—it's deep, intentional work across interaction design, information architecture, and AI-first workflows.

You’ll sit between the founder and a small design team, helping drive clarity, connect the dots, and shape the entire experience. Your fingerprints will be on every detail—from discovery to deployment.

• Impact from Day One: Design a product you and your peers would want to use every day.

• Founder Access: Work side-by-side with a visionary founder, learning how to co-solve in high-trust environments.

• Creative Ownership: Start with a blank slate—no design-by-committee here.

• Flexible Working: London-based hybrid preferred, but flexibility is offered.

• Fast Feedback Loops: Work in cycles where ideas get tested, not trapped.

• You’ve designed complex systems, ideally in startup environments.

• You’re excited about working pre-product-market fit and love the challenge of crafting usable and lovable tools.

• You value feedback and collaboration, especially with fast-thinking founders.

• You’re structured in how you approach information architecture and interaction design.

• You can bring AI-first design thinking into the product (e.g., using AI to sketch, prototype, and iterate).

• You don’t need a team of researchers—you can go deep on your own with real users and raw data.

• You care about creating products people want to use—not just ones they can use.

• Competitive Salary + Equity

• Flexible work setup (remote-friendly, ideally London-based for ad hoc meets)

• Work directly with a Silicon Valley founder and a product-obsessed team

• Real ownership over product direction, design system, and customer experience
