About Brainsquare

Brainsquare designs, develops, integrates and manages business-critical applications. We combine technical expertise with a practical understanding of our customers’ operations, helping teams build and maintain reliable software.

Your mission

As a Senior .NET Software Engineer, you will join an experienced development team working on business-critical applications in Antwerp.

You will design and develop backend components and REST APIs using C# and .NET 8. Working within the existing architecture, you will translate requirements into reliable, maintainable solutions and take ownership of your work from technical design through implementation.

This long-term assignment combines hands-on development with close collaboration. You will contribute to technical decisions, share your expertise and help the team deliver high-quality software.

Your main tasks

  • Take ownership of the technical design and development of backend components.
  • Develop and maintain REST APIs using C# and .NET 8.
  • Implement data access with Entity Framework and work with SQL databases.
  • Apply SOLID principles, Clean Architecture and dependency injection to deliver maintainable code.
  • Investigate technical issues and translate findings into practical solutions.
  • Collaborate with the technical lead and other team members on implementation choices and integration requirements.
  • Contribute to code quality through reviews, unit testing and automated testing practices.
  • Communicate progress, technical decisions and delivery risks clearly.

What we are looking for in you

  • Strong hands-on experience in .NET development, preferably as a senior developer or technical lead.
  • Proven experience building REST APIs with C# and .NET 8.
  • Practical experience with Entity Framework.
  • A solid understanding of SOLID principles, Clean Architecture and dependency injection.
  • Solid SQL knowledge.
  • The ability to take responsibility for both technical design and implementation.
  • Strong analytical and problem-solving skills.
  • Clear communication and a proactive approach to working with colleagues.
  • Fluent English; knowledge of Dutch is a plus.
  • Availability for a long-term assignment in Antwerp.
  • Availability to work on site in Antwerp three days per week, combined with two days of remote work.

Experience with Git, unit testing and automated testing practices, particularly xUnit, is preferred.

Familiarity with microservices architecture and cloud-based solutions, particularly Microsoft Azure, is a plus.

What we offer to employees

As a Brainsquare employee, you will work alongside experienced technical colleagues and have opportunities to develop your expertise. We will discuss the employment arrangement, salary, benefits and mobility options based on your situation and the assignment.

What we offer to freelancers

As a freelancer, you can expect a focused assignment, a clear technical briefing and direct communication throughout the selection process and collaboration. You will join an established team with a concrete need for additional development capacity.

Why choose Brainsquare?

You will contribute to software that supports an industrial business environment, with room to take ownership of backend design and development. The assignment combines hands-on engineering with close collaboration in an existing technical team.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
