At Q-Tech , we are looking for an AI Engineer to join one of our clients in the technology sector .

Preferably based in Barcelona or the surrounding area, but if you bring solid experience, we're open to other locations!

The Role

This is a hands-on engineering role . You will:

• Research, design, and train models suited to the specific needs of our products
• Fine-tune existing open-source and foundation models to maximize accuracy and performance
• Own the full model lifecycle: data curation, experimentation, evaluation, and production deployment
• Collaborate with mobile and backend engineers to integrate models directly into our apps
• Define and track the metrics that drive quality — and continuously push them in the right direction
