🏢 About Eurofins

Eurofins is a global leader in analytical testing services, dedicated to making the world safer, healthier, and more sustainable. Working here means contributing to impactful projects that support environmental and public health, with a strong emphasis on innovation and quality.

About This Role

As a Senior Software Engineer, you will architect and build scalable enterprise applications using .NET Core, Angular, SQL, and Azure. Your work will directly enable Eurofins to deliver reliable testing services globally, while mentoring junior engineers and ensuring high code quality.

💡 A Day in the Life

A typical day starts with a stand-up to discuss progress on user stories. You might spend the morning coding a new API in .NET Core, then pair with a front-end developer to integrate an Angular component. After lunch, you review a junior's pull request, optimize a slow SQL query, and troubleshoot a production alert before logging off.
