You'll join the team behind our Fulfillment Network — the backend that keeps orders, stock, and logistics flowing for thousands of merchants. We care about systems that stay up and get better with every release, and we keep ownership close: the people who build a service also run it. You'll fit in here if you like backend problems that carry real operational weight.
This is a backend-first role — you think of yourself primarily as a backend developer, and the core of the work lives in the .NET / MongoDB space. You'll develop the REST API behind our Fulfillment Network (FFN) and Trade Network (TDN), products used by thousands of customers every day, and own the integration points where backend services and the JTL-Wawi client need to work together seamlessly.
You think in systems and data flows rather than isolated tickets, switch comfortably between technologies, and thrive in a fast-moving, startup-like environment. The principle here is simple: you build it, you run it. You don't own the underlying hardware, but you own your application's operational readiness end to end — when outages happen, you resolve them the same business day. Stability and availability matter to you as much as shipping new features, and you take pride in making the product faster and more reliable with every iteration.
Your Responsibilities
- Develop our FFN / TDN REST API further and own backend features end to end, from design to production
- Build the integration with JTL-Wawi, especially where backend services and client-side behavior need to work together seamlessly
- Support complex business and synchronization scenarios, and handle production incidents and customer-reported issues
- Operate and deploy the API through our pipelines — covering performance optimization, observability, and operational reliability
- Own the operational readiness of your application end to end: you build it, you run it, and you resolve outages within the same business day
