🎯 Who Eurofins Is Looking For

  • 9-11 years of experience in full-stack development using the Microsoft stack, with deep expertise in .NET, C#, MVC, WebAPI, and .NET Core.
  • Strong front-end skills in Angular 13+, JavaScript, TypeScript, jQuery, HTML5, and CSS3, with a portfolio of modern, responsive web applications.
  • Proven ability to apply SOLID principles, design patterns, and n-tier architecture to build scalable, maintainable systems.
  • Experience with Azure services (App Services, Functions, etc.) and MSSQL, including performance tuning and query optimization.

📝 Tips for Applying to Eurofins

1

Highlight your experience with Angular 13+ specifically; many .NET developers focus on backend, so showcase your front-end projects.

Emphasize any work with Azure components, even if minor, as it's a bonus and aligns with Eurofins' cloud initiatives.

3

Provide concrete examples of code reviews you led or participated in, demonstrating your ability to enforce best practices.

4

Mention any experience with SOA projects, as the job description explicitly requires it; describe the architecture and your role.

5

Tailor your resume to include specific metrics (e.g., performance improvements, reduced load times) to show impact.

✉️ What to Emphasize in Your Cover Letter

['Your passion for building scalable, high-quality web applications that contribute to a safer and healthier world.', "Specific examples of how you've applied SOLID principles and design patterns in past projects.", "Your experience with both front-end (Angular) and back-end (.NET Core) development, showing you're a true full-stack developer.", "Your familiarity with Azure and how you've used it to deploy or optimize applications."]
