About This Role
As a Senior Database Developer at Eurofins India, you'll architect and implement distributed data models using Cosmos DB and MongoDB to support large-scale, high-throughput applications for analytical testing services. This role is impactful because you'll directly enable the company's global data infrastructure, ensuring reliable performance for mission-critical systems that process scientific data across multiple continents.
💡 A Day in the Life
A typical day involves analyzing query performance metrics from global laboratory systems, designing new data models for analytical testing workflows, collaborating with development teams on API integrations for data access, and writing automation scripts to optimize database scaling. You'll spend time troubleshooting performance issues across time zones while planning infrastructure improvements to support Eurofins' expanding testing services.
🚀 Application Tools
🎯 Who Eurofins Is Looking For
