How to Apply for Senior .Net Fullstack Developer

at Eurofins

🏢 About Eurofins

Eurofins is a global leader in analytical testing services, operating in over 50 countries with a mission to promote safer, healthier, and more sustainable environments. Working here means contributing to mission-critical software that directly impacts laboratory operations worldwide, from food safety to pharmaceutical testing.

About This Role

As a Senior .Net Fullstack Developer, you will build and enhance next-generation LIMS, customer portals, and e-commerce platforms that streamline global lab workflows. Your work will directly improve efficiency and accuracy in analytical testing, supporting Eurofins' mission of public health and environmental safety.

💡 A Day in the Life

You'll start with a daily stand-up to sync with your Agile team, then dive into coding new features for the LIMS portal—perhaps optimizing a sample tracking module or building a customer dashboard. After lunch, you might review a colleague's pull request, collaborate with QA on test cases, and end the day deploying a hotfix to Azure.

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume without highlighting relevant domain experience (e.g., LIMS, e-commerce) or specific technologies like Angular 13+.
  • Failing to demonstrate hands-on Azure experience—mentioning only on-premises deployments can be a red flag.
  • Overlooking the importance of unit testing and code reviews; be prepared to discuss your testing strategy and tools.
