About algo1

algo1 is a VC-backed, stealth-mode startup 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.

What We Offer

  • Competitive salary and meaningful equity.

  • 25 days' annual leave.

  • The opportunity to define a product millions of people could use every week.

If you’re excited by the idea of shaping the future of retail and eager to make a real impact from day one, we’d love to hear from you.
