Job description

As an Intern Full Stack Developer (Estimation Website), you will build a web application that allows teams to estimate integration requests based on complexity, dependencies, and required effort.

It will also incorporate a feedback loop to check how accurate assessments are.

Your responsibilities

  • Design and develop a modern full‑stack web application

  • Build REST APIs in .NET for storing and retrieving estimations

  • Implement the SQL database and data access layer

  • Develop the UI in React with reusable components

  • Deploy the solution to RedHat OpenShift

  • Write unit and integration tests

  • Document the solution and present it to stakeholders

Your profile

  • Full‑stack interest - You enjoy working across the stack and want to build a complete application end‑to‑end.

  • Basic .NET skills - You can work with C#/.NET or are eager to learn it to build REST APIs

  • SQL understanding - You know how to design simple data models and write queries

  • React fundamentals - You have experience with JavaScript/TypeScript and want to build clean, reusable UI components

  • Structured problem‑solving - You can translate complex input into a clear workflow and logic

  • Attention to quality - You care about writing reliable code and tests

  • Language skills - You communicate fluently in Dutch and English

Our offer

  • A people-oriented work environment with a strong focus on the well-being of our employees

  • A permanent training offer that enables personal and professional development

  • Our office is located in Zwijndrecht and also accessible by Waterbus or shuttle
