Backend / Integration Engineer

Backend / Integration Engineer (Legacy systems)

Logicplan is an early stage company building software for European logistics. We integrate with the systems transport companies already run rather than replacing them, which means a lot of work with older technology: EDI, FTP, SOAP and bespoke connectors.

The role

Own and extend our integration layer across legacy systems. For each system you build a reliable connector that feeds data into Logicplan in real time and keeps running in production. For example, a connector for a Windows service in C# / .NET that ingests orders from a customer's TMS over EDI.

Responsibilities

  • Build connectors that ingest from legacy systems and map and validate heterogeneous XML and JSON into our normalized order model

  • Deliver into our REST API in near real time, idempotent and lossless under network failure

  • Handle failure with retries, exponential backoff and a dead letter path, no duplicated or dropped orders

  • Make it operable: structured diagnostics, health signals, configuration over hardcoding

  • Extend the layer to the next systems as we grow

What we look for

  • Deep C# / .NET (Windows Services, background workers, async, HttpClient)

  • Proven legacy integration experience, not just modern REST

  • REST integration and data transformation (XML, JSON, schema mapping)

  • Strong instincts for failure modes and reliability in distributed integration

  • Energized by moving fast with AI agents while keeping a high bar on what ships

  • EDI or logistics exposure is a plus, not required
