User Experience Designer jobs in United Kingdom

This is your chance to join a close-knit development team where clean code, smart design, and problem-solving come together to make a real impact.

Obsessed with clean code?

Love the challenge of making interfaces intuitive, beautiful, and blazingly fast?

Our client is growing – and we’re on the lookout for a Front End Developer who thrives on crafting sleek, accessible and high-performing interfaces using vanilla JavaScript, HTML, and modern CSS. You’ll join a small, collaborative team that cares deeply about doing things right – from semantic markup to slick, user-friendly experiences that just work.

You’ll be responsible for building and maintaining scalable web applications that meet both client and user expectations. That means translating technical and business requirements into clean, maintainable code, and getting hands-on with everything from layout structure to dynamic interactions. Whether it’s refining an existing component or investigating an edge-case bug, you’ll take ownership of your code and strive for pixel-perfect execution.

• Turning requirements into intuitive user experiences
• Writing well-structured HTML, accessible to all
• Creating responsive, flexible layouts
• Handling interactivity with clean, asynchronous JavaScript
• Diagnosing and fixing bugs with confidence

To hit the ground running, you’ll need around three years of commercial front-end experience and a passion for quality. You’ll have strong fundamentals in HTML, CSS, and JavaScript—and you won’t be afraid to dive into dev tools to fine-tune performance or chase down tricky issues.

You’ll know how to build experiences that work for all users, and you’re happy collaborating with others—whether that’s sharing code, bouncing around ideas, or working through problems with clients.

• 3+ years’ commercial experience
• Strong HTML/CSS/JavaScript skills
• Confidence with async/await, event handling, and debugging
• Solid grasp of accessibility and semantic design
• Visa/Sponsor free ability to work in the UK and would pass an advanced security check

• Experience with Astro or other static site generators
• Familiarity with PHP or basic Linux admin
• Design sensibility and understanding of user flows

This is a fully remote role, though the client is based in Yorkshire and time in the office may be required from time to time. You’ll be part of a close-knit and experienced team that values clarity, integrity, and quality over quantity. They’re known for simplifying complexity across a range of technical services, and this role offers you the chance to contribute to that mission in a meaningful way.

The position is full-time (37.5 hours), permanent, and includes a requirement for basic security vetting. You’ll have the freedom and support to do your best work, with a strong focus on continuous learning and technical excellence.

If you’re ready to build things that are fast, accessible, and genuinely useful – we’d love to hear from you.
