UI/UX Designer

About algo1

algo1 is a VC-backed, stealth-mode company building behavioural AI for the retail industry. Our platform is designed from the ground up. No legacy, no patchwork systems, just a clean slate and a clear vision. Our mission is to bring the intelligence of modern machine learning directly to the in-store shopping experience.

The Role

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.

What You Will Own

• 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 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.

• Evolve the design system that underpins the product.

Essential Qualifications

• 3–5 years designing digital products across UX and UI.

• 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.

• 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.

Nice to Have

• 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.

• Experience designing AI-powered or consumer-facing products.
