Data Science Lead (AI)

Your role

As the Data Science Lead, you will define and uphold Data Science standards supporting Neo, the newly launched group-wide AI platform. You will guide experimentation, evaluation, and refinement of AI models, and coordinate Data Science contributions for new features entering Neo. The role focuses on knowledge quality and alignment with Neo’s platform requirements, working closely with product and engineering teams.

Your tasks

• Lead Data Science activities across streams, ensuring consistent methodology, model quality, and evaluation practices.
• Define experimentation frameworks, test protocols, prompt evaluation methods, and feasibility assessments for new features.
• Supervise model interactions with Neo’s knowledge base to ensure accuracy, relevance, and controlled behaviour.
• Guide Data Scientists in refining models using insights from the feature intake process and platform requirements.
• Work with engineering and architects to ensure models are ready for integration, without taking on MLOps execution.

Your profile

• Bachelor’s or Master’s degree in Data Science, Computer Science, Applied Mathematics, or a related field.
• 7+ years of experience in Data Science, including NLP, retrieval-augmented systems, LLMs, or applied AI solutions.
• Proven ability to lead Data Science teams and establish experimentation pipelines and evaluation frameworks.
• Strong knowledge of LLMs, embeddings, vector search, and model assessment techniques.
• Hands-on experience with Python, notebooks, experimentation frameworks, and AI evaluation tooling.
• Comfortable working cross-functionally with product, engineering, architecture, and knowledge teams.
