Lead Backend Engineer – Pos Platforms Integration
Summary
Lead backend engineer building resilient POS integrations for a global retail brand, focusing on ERP, OMS, CRM, and loyalty systems using Node.js, TypeScript, Kafka, and cloud-native stacks.
In short
At On, retail isn't just a channel—it's an experience. As we scale our global footprint, we're laying the foundation for a future‑ready Point of Sale (POS) ecosystem. To do that, we need robust backend systems that orchestrate flawless integration between the physical and digital, the store and the cloud. We're looking for a Backend Engineer to drive the integration of our POS platform with mission‑critical systems such as ERP, OMS, CRM, and loyalty engines. You'll architect and build resilient services, shape our event‑driven data flows, and ensure our store operations stay fast, reliable, and future‑proof. You'll be joining the Retail Experience team — where technology meets the shop floor and every request matters. If you love crafting clean APIs, streamlining integrations, and optimizing real‑world system performance, you'll feel right at home.
