About the Project

We are looking for a Mid .NET Developer to join us on a web application project in the EdTech industry - an educational platform being delivered for our client. The product is a modern, user-facing web application aimed at an end-user audience that expects a polished, accessible experience.

• Work mode: fully remote

• Equipment: your own hardware

Responsibilities

• Design, develop and maintain backend services and REST APIs in .NET 9 powering the educational platform.

• Model the domain together with the team — translate product requirements into clean, maintainable code and a sensible data model in PostgreSQL.

• Implement and evolve the data layer using Entity Framework 9 — entities, configurations, migrations, querying, and performance tuning.

• Design API contracts

• Take ownership of features end-to-end — from refinement, through implementation and testing, to deployment

• Write clean, testable code and cover it with unit and integration tests; contribute to keeping the test suite healthy and meaningful.

Technical Requirements

Required

Nice to have

• Exposure to Azure — deploying and operating .NET services in the cloud.
