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.

The Role We're looking for a Full Stack Engineer to work closely with product, design, mobile, and machine learning team members to design & build experiences that re define in store shopping. We believe that agentic, LLM driven workflows are here to stay and are looking for engineers who have embraced this and will bring a different perspective to our product development lifecycle. You'll help build engaging & intuitive web experiences and the event driven & real time backend services that power them. You'll work across the stack, implementing highly responsive UI components and real time data flows and APIs on a backend designed for scale & flexibility. What You Will Own Design and implement reactive, real time web interfaces that help manage & redefine what is possible with in store content personalisation Contribute to distributed, event driven backend services connecting our web experience with information from remote devices and external data sources. Model and manage structured and semi structured data across storage layers Integrate AI driven personalisation and real time insights into user flows Contribute to overall system design: service boundaries, data ownership, scaling, and observability Essential Qualifications Built modern full stack applications (Python/Java/Go + React/ts) Worked with a variety of storage technologies (eg. Postgres, Mongo, Redis, Object) Experience with async and bi directional communication protocols and patterns (eg. WebSockets, SSE) Designed and implemented event driven distributed systems (eg. Kafka/Pulsar, RabbitMQ, MQTT, or similar) Actively utilising and experimenting with AI development tools (eg. Claude, Copilot, Cursor) to speed up iteration, prototyping and overall development Nice to Have Built and deployed services on any major cloud providers' services (Azure, GCP, AWS) Experience with container orchestration and service containerisation (Kubernetes, Docker) Worked with real time data collection and/or processing Worked in an IoT or Edge oriented architectures Experience or knowledge in retail POS, inventory, or loyalty systems 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.

About algo1 algo1 is a VC-backed stealth-mode company building behavioural AI solutions 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 As a Staff Engineer, you'll work at the intersection of Product, ML, and Engineering to design and build the retail stack of the future. You'll be building user experiences on top of a platform that combines AI driven content delivery on autonomous edge devices on an IoT network, combined with the backend infrastructure of a cutting edge adTech platform. This isn't a staff role where you "work across the stack", you'll be an integral part of defining the stack. What You Will Own System Architecture: Design and lead the implementation of distributed, event-driven services that bridge the gap between cloud intelligence and edge devices. Technical Strategy: Set the standards for service boundaries, data ownership, and system observability to ensure we scale seamlessly from 1 to 1,000+ locations. AI Integration: Architect the orchestration layer for LLM-driven agentic workflows, moving beyond simple API calls to deeply integrated, autonomous system behaviours. Mentorship & Culture: Continuously raise the bar for engineering excellence. Conduct deep design reviews, mentor mid-level engineers, and champion a culture of "building with AI" and the use of autonomous development agents to accelerate our velocity. Essential Qualifications Track Record: 8+ years of experience, with recent years spent in a Staff, Lead, or Principal capacity at a high-growth startup or a sophisticated scale-up. Full-Stack Mastery: Expert-level proficiency in modern backends (Python, Go, or Java) and high-performance frontends (React/TypeScript). Real-time Protocols: Mastery of async real-time, bi-directional communication protocols and patterns whether that's (WebSockets, SSE) for low-latency, real-time user experiences. "AI-First" Mindset: With AI tools, you have optimised your entire workflow around and can teach others to do the same. Nice to Have Edge & IoT: Experience with "Cloud-to-Edge" orchestration and managing state across geographically distributed systems. Containerised Workloads: High comfort level with Kubernetes and container orchestration in a CI/CD-heavy environment. Distributed Systems: Experience designing and operating event-driven architectures at scale (e.g., Kafka, Pulsar, or MQTT). Domain Expertise: Prior exposure to the complexities of large scale retailTech, adTech, or marTech platforms. 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.
