Founding Product Designer / Frontend Engineer

Founding Product Designer / Frontend Engineer B2B UX Expert Stealth AI Start-up

London - Onsite Equity Included

A stealth-stage, AI-native start-up - backed by Creandum (investors in Spotify, Klarna, Neo4j, Depop) - is rethinking how businesses interact with complex data and AI workflows. With early customer adoption, increasing demand, and a fast-growing team, they're now looking for someone who lives at the intersection of UX design and front-end development to help define the face of the product.

This team is building an LLM-leveraged solution designed for high-value B2B users. It's already in use - and now needs a thoughtful, inventive product and UI/UX expert to make it not just powerful, but deeply usable.

What You'll Own

• Lead the UX strategy and frontend execution for a product that blends AI complexity with business-critical clarity
• Translate user workflows into intuitive, clean interfaces with real-world utility
• Build and iterate on the frontend in React, TypeScript, and modern web tooling
• Partner with AI engineers, founders, and customers to shape every part of the product's user experience

You'll Be a Great Fit If You

• Have designed and built B2B user interfaces, particularly for technical or data-heavy tools
• Are fluent in UX research, prototyping, and frontend development
• Care deeply about user feedback, elegant interaction design, and system clarity
• Are excited to work onsite in London, collaborating daily with a team solving hard technical problems
• Want to shape a product from first principles - and have real equity in what you're building

This is a rare role where your design sensibility and technical skill will both be core to the product's success. You'll help define how people interact with advanced agentic AI - and make that experience simple, powerful, and beautiful.
