The role

This is a senior technical, hands-on role sitting at the intersection of advanced analytics, healthcare strategy and client delivery. You will lead complex data science workstreams, translating ambiguous clinical, commercial and policy questions into robust, decision-focused analytics.

You’ll work closely with consultants, engineers and client stakeholders, acting as a trusted analytical advisor while maintaining a strong focus on delivery quality, reproducibility and impact.

Key responsibilities

Client delivery & advisory

• Communicate complex methods and insights clearly to non-technical audiences
• Operate confidently in ambiguous problem spaces, applying structured problem-solving

Advanced analytics & modelling

• Build predictive models for health outcomes, healthcare utilisation and commercial performance
• Deliver population health analysis, disease burden studies and real-world evidence work
• Apply rigorous statistical methods with a focus on transparency and interpretability
• Work with both structured and unstructured data sources

Data engineering & software engineering

• Design, build and maintain scalable data pipelines integrating multiple data sources
• Write clean, well-tested, reproducible Python code using modern engineering practices
• Use Git for collaborative development, code reviews and CI/CD workflows
• Work with cloud-based storage and compute environments (e.g. AWS or GCP)
• Manage Python environments (e.g. conda, poetry, uv, pip) and use Bash/CLI tooling

Stakeholder & delivery management

• Lead technical discussions, workshops and presentations
• Identify risks, dependencies and delivery constraints within data workstreams
• Maintain high standards of documentation, quality control and delivery excellence
• Support and mentor more junior team members

• Experience designing and implementing complex data pipelines
• Experience working with cloud platforms and secure data environments
• Confident communicator, able to explain technical concepts to non-technical stakeholders
