WHY WE EXIST At algo1, we're reimagining one of the world's most overlooked digital experiences: grocery shopping. Every week, billions of people make hundreds of decisions in stores, often distracted, in a hurry, and with little patience for technology that gets in their way. We believe AI can transform this experience, but only if it's paired with exceptional UX and design. ABOUT THE ROLE We're looking for a UI/UX Designer with exceptional instincts, strong visual craft, and an obsession with interactive design. This role sits equally across UX thinking and UI execution. One day you might be simplifying a complex decision-making flow; the next you'll be refining typography, spacing and motion until every interaction feels natural. - You'll work directly alongside our Head of Design to shape the end-to-end shopper experience, from early concepts through to polished production interfaces. - You'll design flows, interactions, prototypes and systems that solve real problems for real shoppers inside real stores. - You'll help evolve the design system that underpins the product. WHAT YOU'LL DO - Design intuitive end-to-end product experiences, from discovery and concept exploration through to polished production UI. - Turn complex user problems into simple, elegant interaction flows. - Create high-fidelity interfaces with exceptional attention to typography, spacing, hierarchy and visual detail. - Build interactive prototypes to communicate ideas, validate assumptions and refine experiences before development. - Use motion and micro-interactions intentionally to improve clarity, feedback and delight. - Partner closely with engineers to ensure the quality of shipped experiences matches the quality of the design. - Contribute to and evolve our design system, including components, tokens, patterns and documentation. - 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. WHAT GREAT LOOKS LIKE ESSENTIAL - 3–5 years designing digital products across UX and UI. - A portfolio demonstrating thoughtful interaction design and beautifully crafted interfaces. - Strong user experience skills with the ability to simplify complex workflows. - Excellent visual design fundamentals, including typography, layout, spacing, colour and hierarchy. - Experience building and evolving design systems using reusable components, tokens and patterns. - Highly proficient in Figma, prototyping and modern product design workflows. - Strong understanding of interaction design, usability and accessibility principles. - Comfortable using AI as part of your everyday design process. - Thrives in fast-moving, ambiguous environments where shipping and learning happen quickly. NICE TO HAVE - Experience creating or scaling a design system from the ground up. - Motion design skills with a strong understanding of meaningful animation and interaction. - Familiarity with Tokens Studio, design-to-code workflows and modern frontend collaboration. - Experience contributing beyond product into brand systems and visual identity. - Previous startup experience. - Experience designing AI-powered or consumer-facing products. OFFICE IS OUR DEFAULT This is primarily an office-based role for someone who enjoys sketching ideas together, reviewing prototypes side by side, and rapidly iterating with designers and engineers throughout the day. Our office overlooks what we think is London's best garden square, just a couple of minutes from Tottenham Court Road. WHAT WE OFFER - Competitive salary backed by leading venture capital investors. - Meaningful equity in a company building for the long term. - 25 days' annual leave plus bank holidays. - The opportunity to define the UX of a product millions of people could use every week.
