Product Designer (UI/UX) in London

Help reinvent one of the world’s most familiar experiences. Every week, millions of people spend hours shopping for food. Yet despite huge advances in technology and AI, the in-store experience has barely changed. At algo1, you’ll design the interactions that bring behavioural AI into the physical world, helping shoppers discover products, plan meals, make healthier choices, and feel genuinely understood and supported as they shop.

You’ll tackle unusual design challenges at the intersection of digital interfaces, physical environments, and human behaviour, turning complex AI capabilities into experiences that feel simple, useful, and natural. You’ll work directly with founders, engineers, product leaders, and machine-learning specialists. You’ll take ideas from concept to live experience quickly, test them with real shoppers, and use what you learn to make the product better. This is an opportunity to have a major influence on a new kind of shopping experience and help define how people interact with AI in everyday life.

algo1 is backed by leading investors and was founded by two experienced entrepreneurs: a serial entrepreneur with a track record of building category-defining companies, and a retail data and analytics expert whose work has shaped how some of the world’s largest grocers understand their shoppers.

More About the Role

This role reports directly to our Head of Design and works closely with Product and Engineering. You'll own the experience of a completely new kind of retail interaction. Working alongside our Head of Design, you'll define how behavioural AI feels in the hands of millions of shoppers. From the first sketch to the interface that ships in stores, you'll set the standard for how our products look, feel and behave. This isn't a role maintaining an established product or polishing an existing design language. You'll help define the visual language, interaction patterns and design culture of a company that's still being built.

What You'll Own

• Own the shopper experience from first concept to production, making thousands of design decisions that collectively determine how effortless our product feels.
• Turn complex user problems into simple, elegant interaction flows that people can use instinctively.
• Create high-fidelity interfaces with exceptional attention to typography, spacing, hierarchy and visual detail.
• Prototype relentlessly, answering difficult product questions before they're written in code.
• Use motion and micro-interactions intentionally to improve clarity, feedback and delight.
• Raise the quality bar across engineering and design so that what ships feels as considered as what was designed.
• Evolve the design system through reusable components, tokens, patterns and documentation that enable the team to move faster.
• Use AI throughout your workflow to explore concepts, generate ideas, prototype faster and improve design quality.
• Observe real shoppers using the product in stores and translate behavioural insights into better experiences.
