About the opportunity

For one of our clients, we are looking for an experienced Data Engineer to join an innovative company at the intersection of Data, AI and Financial Technology.

This is not a traditional enterprise environment. You'll be joining a company with a genuine start-up mindset where ownership, initiative and collaboration are highly valued. You'll have the opportunity to help shape the data platform that powers next-generation AI solutions, working alongside a passionate team that enjoys solving complex challenges.

If you're looking for a project where you can make a real impact instead of simply maintaining existing systems, this could be the right fit.

Your responsibilities

As a Data Engineer, you'll play a key role in designing and developing the data platform that supports advanced analytics and AI initiatives.

Your responsibilities include:

Designing, building and maintaining scalable data pipelines

Integrating data from a wide variety of internal and external sources

Developing reliable data processing workflows for analytics and AI use cases

Improving data quality, performance and reliability across the platform

Supporting the deployment of AI solutions into production environments

Working closely with software engineers, AI specialists and business stakeholders

Contributing to data governance, security and compliance best practices

Continuously improving the overall data architecture and engineering standards

Your profile

We're looking for someone who combines strong technical expertise with a proactive, hands-on attitude.

Ideally, you have:

Bachelor's or Master's degree in Computer Science, Data Engineering or equivalent experience

At least 5 years of experience as a Data Engineer

Strong experience with Python and SQL

Experience designing and implementing data integration solutions

Hands-on experience with AWS cloud services

Solid knowledge of modern data architectures, including Data Lakes and Data Warehouses

Affinity with AI, Machine Learning or modern data-driven applications

Excellent communication skills and the ability to work in multidisciplinary teams

A pragmatic mindset with a strong sense of ownership

Flexibility and adaptability to thrive in a fast-moving environment

What you'll find

An exciting freelance assignment with real impact

A modern technology stack focused on Data and AI

A collaborative team where your ideas matter

A dynamic environment with a true start-up culture

The opportunity to help build innovative products from the ground up

Hybrid working model with 3 onsite days per week in the Leuven region (fixed requirement)

English-speaking working environment

If you're an experienced Data Engineer who enjoys building scalable platforms, taking ownership and working in an ambitious environment where innovation is part of the daily mindset, we'd love to hear from you
