at Eurofins

🏢 About Eurofins

Eurofins is a global leader in analytical testing services, focusing on making environments safer, healthier, and more sustainable through scientific innovation. Working here means contributing to meaningful projects that impact food safety, environmental protection, and pharmaceutical quality worldwide. The company's mission-driven culture offers engineers the chance to apply technical skills to solve real-world problems with global significance.

About This Role

As a Principal Software Engineer at Eurofins India, you'll lead the design and development of complex Java applications that support critical testing services across 50+ countries. This role involves driving modernization initiatives, migrating legacy systems to modern architectures, and mentoring engineers while remaining hands-on with implementation. Your work will directly impact the scalability and reliability of systems that process millions of analytical test results annually.

💡 A Day in the Life

A typical day involves collaborating with global teams to design Java-based solutions for analytical testing systems, writing code for Spring Boot applications, reviewing pull requests from engineers you're mentoring, and planning modernization efforts for legacy systems. You'll balance technical leadership responsibilities with hands-on development work, ensuring that architectural decisions translate into working software that supports Eurofins' testing services worldwide.

🎯 Who Eurofins Is Looking For

  • Has 6-10 years of hands-on Java development experience specifically on global enterprise projects, not just domestic applications
  • Demonstrates deep technical expertise with Java 8+, Spring Boot, REST APIs, and modern front-end frameworks (Angular/React), plus experience with both SQL and MongoDB databases
  • Has proven experience leading technical direction while remaining actively involved in coding and implementation, not just architecture design
  • Possesses experience with product development lifecycles in Lean Agile/Scrum environments and has successfully migrated legacy systems to modern architectures

📝 Tips for Applying to Eurofins

1

Highlight specific global or enterprise-scale Java projects in your resume, quantifying impact (e.g., 'reduced processing time by 40% for systems serving 20+ countries')

2

Explicitly mention experience with legacy system modernization and migration projects, as this is a core responsibility mentioned in the job description

3

Include examples of technical mentorship or leadership in product development environments, not just individual contributor achievements

4

Tailor your application to emphasize how your skills align with Eurofins' mission of creating safer, healthier environments through technology

5

Prepare concrete examples of complex Java application development using the specific tech stack mentioned (Spring Boot, REST APIs, Angular/React, MongoDB)
