Job description

*100% remote opportunity for candidates based in Poland

Sanoma Learning is the leading European learning company, serving over 20 million students in 11 countries.

We offer printed and digital learning materials as well as digital learning and teaching platforms for primary, secondary, and vocational education.

Our methodologies are developed based on deep teacher and student insights, with a strong focus on understanding their needs.

By combining our educational technologies and pedagogical expertise, we create learning products and services with the highest learning impact.

In our Technology organization, you will join the largest cross-cultural community of Sanoma Learning and contribute to the digital transformation and future of education in Europe.

The Data Scientist / AI Engineer (for Content Consumption Layer) will contribute to advancing AI experimentation at Sanoma Learning.

Reporting to the Senior Director, Head of Data and AI, this role focuses on creating prototypes (PoCs/MVPs) using cutting-edge AI tools – especially in the domain of Generative AI and LLMs.
The role involves translating business needs into well-scoped AI experiments, building functional prototypes, and collaborating with cross-functional teams including product owners, engineers, project managers, and analysts across Sanoma Learning’s operating companies.
This is a hands-on position well suited for a technically capable and curious AI engineer who thrives on experimentation and iteration and is eager to turn new ideas into tangible value.

Key Responsibilities

•    Design and develop PoCs and MVPs using modern AI techniques, with focus on Generative AI, LLMs, and agent-based systems.
•    Contribute to the Content Consumption Layer team development
•    Collaborate with product and experimentation teams to translate business ideas into AI prototypes.
•    Work across the technical stack – from data preprocessing to model implementation, orchestration, and deployment.
•    Build retrieval-augmented generation (RAG) pipelines leveraging Sanoma Learning’s proprietary content.
•    Apply prompt optimization and performance tuning to ensure efficient model usage and optimize costs
•    Contribute to MLOps practices including model versioning, CI/CD, and testing pipelines.
•    Ensure compliance with data privacy standards in close collaboration with security and legal teams.
•    Document solutions and share learnings, contributing to internal best practices and experimentation infrastructure.
•    Stay up to date with the evolving AI ecosystem and bring in relevant tools and techniques.

Must-have requirements

Education
• Bachelor’s or Master’s degree in Computer Science, Machine Learning, AI, Data Science, Engineering, or a related technical field.
