Project Description

Working on creating early AI prototypes to drive experimentation in Sanoma Learning.

Role Responsibilities

The Data Scientist / AI Engineer 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.
• 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

• Bachelor’s or Master’s degree in Computer Science, Machine Learning, AI, Data Science, Engineering, or a related technical field.
• Relevant certifications in AI/ML, cloud platforms, or MLOps are a plus.

Experience

• 3–5 years of hands-on experience in AI engineering, machine learning, or applied data science roles.
• Experience developing PoCs or MVPs using LLMs, transformers, or related GenAI techniques.
• Familiarity with RAG systems and vector databases
• Exposure to cloud-native tools and infrastructure (e.g., AWS, GCP, Azure), Docker/Kubernetes, and orchestration tools like Airflow or Prefect.
• Experience implementing or adapting LLM evaluation frameworks is a plus.
• Understanding of compliance and governance requirements (e.g., GDPR, responsible AI practices).
• Prior exposure to EdTech or publishing is beneficial but not required.

Skills

• Solid understanding of transformer-based models and prompt engineering techniques.
• Proficiency in Python and experience with libraries such as LangChain, LangGraph, or OpenAI/Anthropic APIs
• Familiarity with vector databases, embedding pipelines, and chunking strategies.
• Ability to develop agentic workflows and multi-step AI task execution.
• Working knowledge of MLOps, version control, and model deployment pipelines.
• Strong analytical thinking and experimentation mindset.
• Comfortable working in agile, cross-functional environments, with good written and verbal communication skills.
• Curious, adaptable, and eager to learn and implement new technologies in a fast-evolving space.

Personal Attributes

• Data-driven decision-making approach
• Proactive and positive “can-do” attitude, demonstrating initiative and resilience.
