This is a role for someone comfortable owning ambiguity, not waiting for a fully specified ticket. You will help build the NLP, generative AI, and RAG capabilities that let users query complex health databases in plain language safely, accurately, and grounded in trusted data.\n\nResponsibilities: \nOwn data science problems end-to-end from ambiguous business or clinical questions to scoped problems, models, and measurable outcomes.\nDevelop predictive and statistical models across health domains: supply chain demand forecasting, claims and denial analytics, and population health indicators.\nDesign experiments and validation approaches defining success metrics, baselines, and evaluation criteria before building.\nWork with large-scale, multi-country datasets, handling the messiness, gaps, and inconsistencies of real-world health data.\nBuild and improve natural-language-to-data capabilities: LLM- and RAG-based systems that let users query health databases in plain language, including text-to-SQL, retrieval over schema and documentation, and grounding model outputs in trusted data.\nApply NLP and generative AI techniques to unstructured health data clinical notes, documents, and free-text fields where structured extraction adds value.\nPartner with data engineers to productionise model feature pipelines, retraining, monitoring, and drift detection rather than handing off notebooks.\nCollaborate with product and domain teams to translate clinical and operational questions into well-scoped data problems with clear success criteria.\nCommunicate findings and their limitations honestly to technical and non-technical stakeholders, including government counterparts.\nSet analytical standards for the team's methodology, rigour, reproducibility, and documentation and mentor junior analysts and data scientists.\nContribute to architecture and tooling decisions for the analytics and ML stack.\n\nRequirements: \n5+ years of experience in data science, with a track record of shipping models and analyses that reached real users or decisions.\nDemonstrated experience on large-scale projects working with high-volume data and systems where scale and performance matter.\nProven ability to handle ambiguity: you can take an open-ended problem, structure it, and drive it to a defensible answer with limited direction.\nStrong Python for data science: Pandas, NumPy, scikit-learn, and at least one deep learning or advanced modelling framework where relevant.\nStrong SQL and hands-on experience with large or analytical datasets; comfort with columnar databases such as ClickHouse, BigQuery, Snowflake, or DuckDB is a plus.\nSolid grounding in statistics and machine learning fundamentals: you can choose the right method and explain why, and you know the difference between correlation and a usable signal.\nHands-on experience with Natural Language Processing (NLP) text processing, embeddings, and language model fundamentals.\nPractical experience with generative AI and large language models (LLMs) prompting, evaluation, and building applications on top of foundation models via APIs or open-weight models.\nExperience designing and building Retrieval-Augmented Generation (RAG) systems, chunking, embeddings, vector search, and retrieval quality and an understanding of how to ground LLM outputs to reduce hallucination.\nFamiliarity with natural-language-to-SQL / text-to-data approaches and their failure modes, especially the accuracy and safety concerns of letting an LLM query a real database.\nExperience taking models to production and maintaining them, monitoring, retraining, and model quality over time, not just training and handing off.\nClear communication: you can defend a methodology to a technical peer and explain the same result plainly to a non-technical decision-maker.\nStrong data quality and epistemic discipline: you surface uncertainty and caveats rather than overstating confidence.\n\nNice to Have: \nExperience with health data FHIR, claims, supply chain, or logistics is a strong differentiator but not a hard requirement.\nExperience with time-series forecasting, causal inference, or optimisation in an operational context.\nFamiliarity with LLM tooling and frameworks like LangChain, LlamaIndex, or equivalents and vector databases such as pgvector\nExperience evaluating LLM and RAG systems, systematically building eval sets and measuring answer accuracy, faithfulness, and retrieval quality rather than relying on spot checks.\nFamiliarity with MLOps tooling experiment tracking, model registries, and pipeline orchestration (Dagster, Prefect, or Airflow).\nExperience with dbt or equivalent transformation tooling and lakehouse or medallion architecture patterns.\nComfort working in a B2G context where data sovereignty, auditability, and reproducibility are first-class concerns.\nPrior experience mentoring or setting technical direction for a small data team.\nSkills\nGenerative AI, LLM, Large Language Model, NLP, Natural Language Processing, Python, RAG, Retrieval-Augmented Generation,
