Founding Product Designer
Location: London (Hybrid - Flexible 2-3 days/week in King’s Cross)
About the Company
Our client is building the first monetization and payments platform for AI agents, enabling businesses to scale the agency economy into the trillions. Every AI company will need a billing and pricing solution to unlock its full potential, and this company is redefining how AI-powered businesses charge and demonstrate value.
Founded by experienced entrepreneurs with a track record of scaling and exiting category-defining companies, the team is backed by EQT and Sequoia. They are now assembling world-class talent to define a new industry category.
Why This Role?
As the Founding Product Designer, you’ll play a key role in shaping an entirely new category of software. Rather than following existing UX patterns, this role requires creating new ones to solve real-world challenges in AI monetization. For someone who thrives in ambiguity, has a strong product vision, and can execute quickly, this is a rare opportunity to make a significant impact.
What You’ll Do
* Lead the end-to-end design process for the core product, from concept to production.
* Work closely with engineering and product leadership to craft a UX that helps AI companies price, bill, and grow their businesses.
* Define the information architecture for a product that has no direct comparisons, requiring first-principles thinking and innovation.
* Rapidly prototype and iterate, testing ideas with design partners and customers.
* Design clear, compelling interfaces that communicate the value of AI agents and enable seamless transactions.
* Operate as a hybrid Product Designer/Product Manager, balancing strategic thinking with hands-on execution.
* Participate in customer meetings and product discussions to gain deep insights into AI-driven monetization.
What They’re Looking For
* 5+ years of experience in product design, ideally in B2B SaaS, fintech, or AI.
* Experience in early-stage or 0→1 product development, where there’s no playbook, and you have to define the path.
* Ability to work at a systems level, designing dashboards, workflows, and information architecture for complex problems.
* A strong point of view on design, with the ability to challenge assumptions and think beyond existing patterns.
* Strong collaboration skills—able to work closely with engineers, product managers, and founders in an iterative, feedback-driven environment.
* A portfolio showcasing strong UX, product thinking, and an ability to solve complex problems through design.
Bonus Points
* Experience designing for AI-driven products, fintech, or payments platforms.
* Background in data visualization, dashboards, or information-heavy UX.
* Familiarity with AI monetization, LLMs, or agent-based technologies.
* Experience in startups selling to other startups, where design expectations are extremely high.
* Knowledge of AI tools like v0.dev or lovable.dev.
What Success Looks Like
* Deep understanding of the problem space, with participation in customer conversations and early prototyping.
* Creation of foundational UX/UI patterns and early iterations of the core product.
* Ownership of the design vision, working closely with the founding team and engineers to launch an MVP with real-world adoption.
Why Join?
* Build from the ground up: Be the first designer at a well-funded startup solving a multi-trillion-dollar problem.
* Work with world-class founders: Learn from leaders who have built and exited successful businesses.
* Shape the AI economy: Help define how AI-powered businesses monetize.
* Competitive salary + equity: Get in early at a company positioned for significant growth.
