at Eurofins

🏢 About Eurofins

Eurofins is a global leader in analytical testing services, committed to promoting safer, healthier, and more sustainable environments. Their mission-driven work impacts industries like pharmaceuticals, food, and environment, offering a sense of purpose beyond typical tech roles.

About This Role

As a Senior Software Engineer, you'll be a full-stack developer responsible for analysis, design, and development of .NET and WPF applications within a high-impact software product suite. Your work will directly support Eurofins' mission by enabling efficient laboratory workflows and data management.

💡 A Day in the Life

Your day might start with a stand-up meeting to discuss progress on features for the lab software suite. You'll then dive into coding tasks like implementing a new WPF module for sample tracking, writing unit tests, and debugging a production issue reported by lab technicians. After lunch, you might collaborate with QA to review test cases or participate in a design review for a microservice endpoint.

🎯 Who Eurofins Is Looking For

  • 5-8 years of experience in .NET and WPF/Angular, with deep proficiency in C#, WPF/XAML, Web APIs, LINQ, Entity Framework, and SQL.
  • Strong background in object-oriented design and UML, with experience in SOA or microservices architecture.
  • Passion for code quality: writes well-factored, optimized, unit-tested code and has excellent debugging skills.
  • Familiarity with Agile methodologies (Scrum/Kanban) and experience with performance management in C# or SQL.

📝 Tips for Applying to Eurofins

1

Tailor your resume to highlight specific WPF and .NET projects, especially those involving complex UIs or data binding.

3

Include links to your GitHub or code samples demonstrating clean, unit-tested code and use of design patterns.

4

Mention any experience with Azure DevOps, CI/CD, or cloud deployment, as it's a preferred skill.

5

In your cover letter, explicitly connect your past work to Eurofins' mission of improving health and sustainability.
