Do you want to develop modern, scalable systems in technology-intensive environments where you can influence both solutions and technical choices? Here you will work closely with both product and technology – in teams where you have influence over solutions and technical choices.

We are looking for a Fullstack Developer with a backend focus to join our team in Jönköping. The role covers the entire development chain, from requirements analysis and system design to implementation, testing, deployment, and further development. You will work with tools and systems in a product-oriented environment, connected to systems and tools used in the development and testing of robotics solutions, where quality, stability, and user benefit are in focus.

Your future responsibilities:

  • Develop scalable backend solutions in C# and .NET
  • Build and further develop APIs and backend solutions for tools and systems in a complex product environment
  • Develop desktop applications and internal tools in WPF
  • Work with cloud-based solutions in Azure, including deployment and infrastructure
  • Work with the entire lifecycle from requirements to testing, release, and maintenance
  • Contribute to code quality, automated tests, and CI/CD flows
  • Troubleshoot, optimize, and further develop existing systems

We are looking for someone who has:

  • A Bachelor's or Master's degree in Computer Science or another relevant field.
  • Several years of experience in software development in C# within the .NET framework.
  • Experience with ASP.NET Core and backend development, preferably with .NET-based web technologies (e.g., Blazor).
  • Experience with Azure (cloud services and infrastructure)
  • Experience in agile development projects, preferably in collaboration with cross-functional teams.
  • Fluency in Swedish and English, both spoken and written.

Additional qualifications:

  • Experience with automated tests, unit tests, and test-driven development
  • Experience with tool development close to embedded systems or similar technical environments
  • Experience with Unity
  • Experience with cross-platform or mobile development (e.g., .NET MAUI, iOS, or Android)

Your personal qualities

You have a curious and solution-oriented attitude, are self-driven in your work style, and see the value in close collaborations – both with customers and colleagues. You are interested in the latest technologies within the software field and see the consulting role as an opportunity to grow professionally while contributing value to every project you take on.
