About algo1

We’re 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

We’re looking for a Full Stack Engineer with Frontend specialism to work closely with product, design, mobile, and machine learning team members to design & build experiences that re‑define retail shopping. You’ll help help build engaging & intuitive web experiences using highly responsive UI components and real-time data flows.

We are looking for people of varying experience levels who are willing to take the lead on delivering features end-to‑end. You will have already embraced agentic coding and how it can be used to enhance individual and team productivity.

What You Will Own

  • Design and implement reactive, real‑time web interfaces that help manage & redefine what is possible with in‑store content personalisation
  • Understand the different users of the platform and advocate for their needs
  • Translate user and business needs into a functional web application using RBAC and ReBAC to cater to the different users
  • Contribute to API and broader system design & documentation as part of end‑to‑end delivery of features

Essential Qualifications

  • Strong understanding of UX principles and web design fundamentals
  • Expert in Typescript and React
  • Experience with real‑time and bi‑directional communication protocols and patterns (eg. WebSockets, SSE)
  • Built and deployed services on any major cloud providers’ services (Azure, GCP, AWS)
  • AI‑Native development: Fast iteration & prototyping using AI tools such as Copilot, Claude or Cursor

Nice to Have

  • Experience in backend development and event‑driven architecture
    • Our stack includes python, FastAPI, postgres, Kafka and MQTT
  • Worked with 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.
