Job description

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. The first connector is a Windows service in C# / .NET that ingests orders from a customer’s TMS over EDI., * 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

Requirements

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

About the company

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.
