Freelance Lead UX/UI Designer

Freelance Lead UX/UI Designer — Fully Remote (UK-based)

We're working with a leading marketing agency to build a select group of freelance UX/UI designers to support an exciting pipeline of global brand campaigns.

We're looking for a Lead UX/UI Designer who pairs exceptional craft with the confidence to lead projects end to end, with minimal oversight. This is a hard role to fill well, so we're focused on finding someone genuinely senior.

What you'll bringDesign craft: exceptional UX (user flows, information architecture, interaction design) and polished, distinctive UI. You're fluent in responsive, screen-agnostic design, wireframing and prototyping (low- to hi-fi), and have a strong visual foundation across colour, typography, layout and hierarchy. You work confidently within design systems and can build one from scratch.

Breadth: solid grasp of A/B testing and digital optimisation, working knowledge of qualitative and quantitative research, accessibility and semantics, and experience across CMS, commerce, mobile and web. You understand HTML/CSS well enough to design within its constraints and hand off cleanly to developers. Iconography and illustration skills a must; UI animation and motion a nice-to-have.

Client leadership: you own the client relationship — leading meetings, reading the room, and aligning user needs with business priorities without escalating every decision. You identify opportunities, scope and pitch work, facilitate workshops, and lead a project or workstream from beginning to end.

Mindset: you know where AI adds value and where a human must stay in control — critiquing and curating AI output into something usable, and defending that line. You build in accessibility, ethics and compliance from the start, and bring curiosity, empathy and a sharp eye for detail.

Tools: Figma (incl. Figma AI/Make) and Adobe CC; generative and text-to-prototype tools (Figma Make, Lovable, Cursor/Vercel); AI-assisted research and documentation; analytics (Hotjar, GA, Contentsquare); testing platforms (Optimizely, UserZoom, UserTesting); Agile (Scrum, Kanban).

The details

Fully remote, but you must be UK-based. Day rate up to £500 for the right person.
