Full stack .NET developer

As a Full Stack .NET Developer, you’ll play a key role in building high-quality software solutions that power our internal and external operations. Working closely with your team, you’ll transform business needs into clean, efficient, and scalable code — while ensuring everything is well-documented and thoroughly tested. You’re not just writing code; you’re shaping the systems that keep our business running smoothly.

We’re looking for a developer who is curious, collaborative, and passionate about creating great software. If you love problem-solving, clean architecture, and continuous improvement, we’d love to have you on our team.

What You’ll do

• Develop and maintain custom-built applications, contributing to bi-weekly release cycles.

• Review code and provide constructive feedback to help elevate the whole team.

• Refactor and optimize existing code to enhance performance and reduce technical debt.

• Solve daily challenges, balancing short-term fixes with sustainable long-term solutions.

• Translate user stories into clear development tasks and write comprehensive unit tests.

• Proactively propose improvements to architecture and system design, collaborating with the IT Manager or Team Lead.

Who You Are

• You have 3+ years of experience as a Full Stack or Back-End Developer.

• Skilled in HTML, CSS, C#, SQL, and .NET Core.

• Experienced with Azure DevOps or similar platforms.

• Knowledge of Microservices, Kubernetes, and preferably Microsoft Azure.

• Fluent in English, both spoken and written.

• You thrive in an Agile environment.

• You’re communicative, analytical, and well-organized — a true team player.

ABF is a strongly internationally-oriented trading company, with over 11 million products in stock. Although the market we operate in is conservative, ABF as a company certainly is not.

Only 6% of our customers are located in the Netherlands; the remaining customers are primarily in other European countries and are further fragmented worldwide
