AI-Enhanced Backend Software Engineer - Customer Integration

Responsibilities

We are building AI-enhanced digital products with a clear purpose: to help people all over the world see and hear better. At our Digital Excellence Hub in Málaga, you’ll join a senior, international engineering team focused on shipping high-quality software faster and smarter using the latest AI development tools.

Within our Customer Intelligence domain, we are building the backbone that powers customer-centric experiences across the entire Fielmann ecosystem.

One of our key initiatives is a scalable data ingestion platform that connects core operational systems with our customer engagement toolchain.

Your mission will be to design and build a robust, event-driven backend service layer that:

• Ingests and transforms high-volume operational data
• Ensures reliable, secure, and compliant data flows
• Enables real-time and batch integrations
• Serves as the foundation for analytics, automation, and AI-driven personalization

You will be building infrastructure-grade services that become mission-critical for how we understand and serve our customers.

This is your opportunity to shape the future of AI enhanced software engineering in a real-world, purpose-driven environment.
