## Description

Are you a C# Developer who enjoys building complex software, working with modern architectures and developing applications used by customers worldwide? Would you like to develop new features, build integrations and help migrate legacy systems to the cloud?
For an international family owned business in Roosendaal, the Netherlands, we are looking for a Medior C# Developer to join the development team. The company manages an impressive portfolio of approximately 4 million products and serves customers around the world. No less than 80% of its customers are based outside the Netherlands. The technology behind its international webshop is largely developed and maintained in house. The new webshop has recently gone live, marking the beginning of an exciting next phase: developing new features, integrating systems and modernising existing software.
Important: You must live within a maximum 45 minute door to door commute of the office. You will work on site in Roosendaal three days per week.

What will you do?
You will join a development organisation consisting of nine developers across two teams, supported by an additional development team outside the Netherlands.
You will work on the continued development of the webshop and its underlying systems, focusing on new features, technical integrations and the modernisation of existing applications.

Your responsibilities will include:

 * Developing and maintaining software using C# and .NET.
 * Building new features for the international ecommerce platform.
 * Developing modern web applications using Blazor.
 * Building and optimising APIs and integrations between different systems.
 * Working within a microservices architecture.
 * Developing and optimising SQL databases and queries.
 * Contributing to the further development of the Microsoft Azure cloud environment.
 * Using Azure DevOps for source control, collaboration and CI/CD processes.
 * Working with Kubernetes to deploy and manage applications.
 * Contributing to the modernisation of existing software and the migration of legacy applications to the cloud.
 * Collaborating with developers and technical colleagues in the Netherlands and Moldova.
 * Identifying opportunities to improve performance, maintainability, code quality and overall system architecture.

You will have the opportunity to contribute ideas, take ownership of technical solutions and help shape the future development of the platform. Your work will directly support the company's international operations.
