AI-Enhanced Software Engineer - Customer Intelligence

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 Customer Intelligence, we build and operate the backbone that powers customer-centric experiences across the entire Fielmann ecosystem. Our products make customer and order information securely available across online shops, stores and customer service. They support millions of customers while respecting consent, access-control and data-protection requirements.

One of our key initiatives is building a scalable customer data infrastructure that connects customer and order data across our core operational systems.

Your mission will be to build and maintain robust backend services that:

• Handle high-volume of operational data
• Ensure reliable, secure, and legal-compliant data flows
• Unify customer and order data across various sales channels
• Enable real-time and batch data handling
• Serve as the foundation for customer authentication, customer identity resolution and customer identity stitching.

You will be building enterprise-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.
