Job Description

Data Scientist responsible for creating a Medical Decision-Support Engine using AI and medical data. Leveraging LLMs and Knowledge Graphs to enhance mental health diagnostics.

Responsibilities:

  • Design robust pipelines for processing Electronic Health Records (EHR) and medical literature.
  • Implement rigorous multi-stage validation frameworks (Sensitivity/Specificity analysis) to ensure clinical safety and model reliability.
  • Adapt Large Language Models using SFT, DPO, or PEFT (LoRA/QLoRA) for specialised medical domains and complex clinical diagnostic reasoning.
  • Architect hybrid retrieval systems that combine vector databases with Knowledge Graphs to eliminate hallucinations and ensure factual grounding.
  • Develop methods to make model outputs transparent.

Requirements:

  • Expert knowledge of Transformer architectures and hands-on experience fine-tuning LLMs (Llama 3, Mistral, etc.)
  • Hands-on experience with Knowledge Graphs, Triple-stores, or Graph Databases (Neo4j, ArangoDB) and Graph Neural Networks (GNNs).
  • Proficiency in LangChain / LlamaIndex and vector search engines (Pinecone, Milvus, or Weaviate).
  • Practical experience with SHAP, LIME, or custom attention-mapping techniques for model interpretability.
  • Strong background in statistical validation for high-stakes environments and handling imbalanced messy data.

Benefits:

  • Meaningful social impact: your work directly contributes to better patient outcomes, faster recovery, and a significant reduction in diagnostic errors.
  • Cutting-edge stack: work at the absolute forefront of AI, combining LLMs with structured Knowledge Graphs (Graph RAG).
  • Solve the "why": you won't just build a model, you'll build a system that clinicians can trust because they understand its logic.
