Data Scientist; AI National Security - eSC​/eDV

As a Consulting Data Scientist, you will:

• Design, develop and deploy AI and Data Science solutions across multiple client engagements.
• Translate complex and often ambiguous business problems into practical analytical and AI-driven solutions.
• Deliver Generative AI use cases including Retrieval-Augmented Generation (RAG), semantic search, knowledge retrieval, intelligent assistants and agentic workflows.
• Apply machine learning, statistical analysis and predictive modelling techniques to structured and unstructured datasets.
• Conduct exploratory data analysis, feature engineering, model development, evaluation and validation activities.
• Evaluate, fine‑tune and optimise AI models to improve performance, reliability, explainability and business value.
• Work closely with Data Engineers, Architects, Product Owners and client stakeholders throughout the delivery lifecycle.
• Support the deployment and operationalisation of AI solutions through cloud platforms, APIs, MLOps practices and modern integration approaches.
• Communicate technical findings and recommendations to both technical and non-technical audiences.
• Contribute to best practices across AI engineering, governance, responsible AI and secure-by-design delivery.
• Support and mentor junior practitioners where appropriate.

Successful candidates will combine strong analytical capability with modern AI engineering practices, helping clients unlock value from traditional Machine Learning, Generative AI, Retrieval-Augmented Generation (RAG), semantic search, agentic workflows and advanced analytics.
