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 to work closely with product, design, mobile, and machine learning team members to design & build experiences that re‑define in‑store shopping. You’ll help build engaging & intuitive web experiences and the event‑driven & real‑time backend services that power them.

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.
