Functie omschrijving

We are currently developing our cloud web portal, mobile app and scanner to become ready for our next customers. As we expect in the coming year to implement our solution at the supply chains of the largest food retailers in the world, we have exciting times ahead. 

We will add lots of new features to our Android (Xamarin) app and web platform and get more robust for heavy usage. Also, we have to think about how we can guarantee near 100% uptime and revisit deployment structures. To integrate into business processes and exchange data between our customers, we will need to further develop APIs. All our new features are split up in user stories and are executed in sprints. You will primarily work with our junior developer and a software tester. Also, you will participate in agile ceremonies, to estimate the user stories, review acceptance criteria, and do sprint reviews. Furthermore, we work in Microsoft’s Azure environment and have CI/CD pipelines in Azure DevOps and also use it for writing and tracking our user stories.

  • Implementing automated unit test cases surrounding your code. 
  • Design and recommend software solution architectures.
  • Write design specification documents for new projects.
  • Using a project scheduling application, determine tasks, assign resources, and manage a project.

  • Experience with (no)SQL.
  • Experience in JavaScript or Angular.
  • Experience with the Windows platform.
  • Experience with web systems and web service technologies (HTML, CSS, REST, etc.).
  • Knowledge of .NET is a plus.
  • Full stack web development experience is a plus.
