Project Description

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

Size And Composition Of Your Current Team

You will be joining a cross-functional team of 6 professionals: 3 Data Scientists, 2 Analysts, and 1 AI Project Manager.

Role Responsibilities

The Senior Data Scientist / AI Engineer will play a critical role in advancing AI experimentation at Sanoma Learning. Reporting to the Senior Director, Head of Data and AI, this position is designed for a senior technical expert who can lead the development of advanced AI solutions – from ideation through PoC/MVP and into productization.

The role involves building scalable prototypes (especially LLM-based and agentic systems), translating business ideas into technical solutions, and working in close collaboration with cross-functional teams, including product owners, project managers, architects, analysts, and operating companies stakeholders.

Beyond hands-on work, this role is expected to coach junior colleagues, embed best practices, and help raise the AI maturity across the organization.

Key Responsibilities

• Design, develop, and deploy PoCs and MVPs using cutting-edge AI techniques, with a strong focus on Generative AI, including LLMs, and agent-based architectures.
• Translate business challenges into well-scoped AI use cases and deliver end-to-end prototypes in collaboration with product and experimentation teams.
• Work hands-on across the stack – from data ingestion and model development to orchestration, deployment, and monitoring.
• Implement retrieval-augmented generation (RAG) pipelines connected to Sanoma Learning content and multi-step reasoning workflows for practical enterprise use.
• Optimize performance and scalability through techniques like prompt tuning, caching, and efficient inference.
• Establish engineering and MLOps best practices, including versioning, CI/CD pipelines, testing, and cloud-native deployment.
• Ensure AI solutions meet data privacy and compliance standards, working closely with legal and security teams.
• Coach junior team members, foster AI engineering best practices, and help build internal capability across Sanoma Learning.
• Contribute to internal knowledge sharing, including documentation, workshops, and reusable component libraries.
• Stay current with AI research and tooling, evaluating emerging technologies and integrating them into experimentation workflows where relevant.

Must-have Requirements

Education

• Master’s or PhD in Computer Science, Machine Learning, AI, Data Science, Engineering, or a related technical field.
• Additional certifications in cloud engineering (e.g., AWS/GCP), MLOps, or GenAI tooling are an advantage.

Experience

• 5+ years of hands-on experience in data science, AI engineering, or applied machine learning roles, and 2+ years of experience with Generative AI
• Proven experience delivering production-ready PoCs and MVPs with LLMs, transformers, or agentic architectures.
• Hands-on work with retrieval-augmented generation (RAG) systems and vector databases.
• Strong background in cloud-native development (AWS, GCP, Azure), containers (Docker, Kubernetes), and orchestration tools (Airflow, Prefect).
• Experience implementing LLM evaluation and testing frameworks.
• Familiarity with data governance and compliance in AI deployments (e.g., GDPR, EU AI Act).
• Strong track record in mentoring, technical coaching, and/or building internal communities of practice.
• Previous experience in edtech or publishing is a plus.

Skills

• Deep understanding of transformer-based models, prompt engineering, and generative AI workflows.
• Strong programming skills in Python, with experience using frameworks like LangChain, LangGraph, OpenAI API.
• Expertise in retrieval systems, embedding generation, and vector search integration.
• Competence in building agentic pipelines, integrating tools and services for complex task resolution.
• Strong command of MLOps principles, CI/CD, and infrastructure as code (IaC) for deploying and maintaining scalable systems.
• Ability to evaluate model performance using a combination of quantitative and qualitative techniques.
• Excellent communication skills and the ability to collaborate across product, business, and technical teams.
• Self-driven, pragmatic, and excited by the challenge of building real-world AI solutions that deliver tangible value.

Personal Attributes

• Data-driven decision-making approach
• Proactive and positive “can-do” attitude, demonstrating initiative and resilience.
• Strong organizational skills, adept at managing multiple tasks simultaneously.
• Self-motivated, consistently seeking opportunities for improvement and innovation.
• Passionate about opportunities in Data and AI space
