Senior Backend Engineer

The backend is where the digital twin either earns its reliability or quietly loses it. As Senior Backend Engineer at WareBee you will own the contracts the product lives and dies by — the ingestion pipelines that turn warehouse data into a model, the APIs, durable storage, background work, and the observability that lets a small team operate them with confidence at 3 am.WareBee runs on two engines: Physical AI — a living, spatial model of the warehouse floor, its racks, aisles, and movement — and Process AI, which learns how work actually flows through it. Your systems are what keep both fed, fast, and reliable.What you will doDesign APIs and data models that are obvious to the next person who touches themBuild ingestion and background processing that handles large warehouse datasets without losing workPair with frontend and optimisation teammates to ship features end to endMake production legible — tracing, structured logs, useful errors, fast recoveryPush back on complexity that does not earn its keepWhat we are looking forSeveral years building production backends that other engineers extended after youComfort with relational thinking, schema design, and the failure modes of distributed systemsA test discipline that means deployments rarely surprise youBias toward boring, type-safe technology you can hand offCare about the developer experience of the people who come after youHands-on warehouse, logistics, or supply-chain experience — you’ve seen how a real floor runs (a strong plus)What we offerSenior ownership of the systems behind a product warehouse managers depend onA small senior team where engineering decisions are made by engineersHybrid in Cambridge, UK or Tel Aviv, Israel — or fully remote
