Senior Data Scientist

Senior Data Scientist

London – Remote

Salary range - £70,000-£100,000 depending on experience level

About the Role

We are looking for a Senior Data Scientist to join a mission-driven team building data-driven solutions that improve outcomes in the healthcare sector. In this role, you’ll design, build, and deploy predictive models that harness real-world behavioural data to drive impactful insights.

This is a hands-on role ideal for someone who thrives in a collaborative, fast-paced environment and is excited by the challenge of applying data science at scale. You’ll work closely with cross-functional teams to operationalize models, support product development, and contribute to a modern MLOps pipeline.

What You’ll Do

• Develop and deploy predictive models using behavioural and real-world data
• Translate complex datasets into actionable insights that improve healthcare outcomes
• Contribute to the full ML lifecycle, from data wrangling and feature engineering to model deployment and monitoring
• Collaborate with engineering and product teams to ensure models are integrated into production systems via scalable pipelines
• Champion best practices in MLOps, including CI/CD for ML, model versioning, testing, and monitoring
• Design experiments (A/B testing, uplift modelling) to measure impact and optimize performance

What We’re Looking For

• PhD background in a relevant field
• Proven commercial in data science, with a strong foundation in predictive modelling and machine learning
• Proven experience working with consumer behaviour data—ideally within healthcare, digital health, or related B2C environments
• Strong programming skills in Python, with experience using libraries like scikit-learn, XGBoost, and pandas
• Practical experience in MLOps or strong knowledge of model deployment (e.g. MLflow, Airflow, Docker, Kubernetes, model monitoring tools)
• Familiarity with cloud environments (AWS, GCP, or Azure) and data pipelines
• Excellent communication skills—able to explain technical work to non-technical stakeholders and come to meetings with ideas
