Senior Data Scientist

Job overview

We are seeking an experienced Senior Data Engineer to provide technical leadership and hands-on expertise within the Southwest Secure Data Environment (SWSDE). SWSDE enables secure use of health and care data for research, innovation, service improvement and transformation. Working with NHS organisations, universities and research partners, it supports better outcomes and data-driven decisions.

The postholder will lead the design, development, testing and implementation of complex data pipelines, models and research-ready datasets. Working with NHS providers, researchers, technical teams and delivery partners, you will turn complex requirements into secure, scalable and reusable engineering solutions.

You will combine strong technical skills with the ability to lead complex engineering activity, solve difficult data problems and develop other engineers. Essential experience includes SQL, Python, data integration, data modelling and modern engineering practices.

NHS or healthcare data experience is valuable, but we also welcome applicants from research, public-sector or other complex, regulated environments who offer strong engineering skills and fresh thinking.

The role is administratively based in Bristol, with applications welcome from across the Southwest. Flexible regional and home working is available, with travel to partner organisations as required.

Advert

The postholder will:

· Lead the design, development, testing and delivery of complex health and care data pipelines, models and research-ready datasets.

· Translate research, operational and provider needs into technical specifications and secure, scalable, reusable solutions using SQL, Python and modern engineering technologies.

· Work with NHS providers to understand source systems, datasets, coding, data flows and constraints.

· Profile and validate data, resolving quality issues and leading extraction, ingestion, transformation, linkage and curation.

· Automate processes to improve the reliability, repeatability, traceability and efficiency of data delivery.

· Coordinate engineering across projects, datasets and providers; identify risks, dependencies, capacity issues and barriers, acting or escalating as needed.

· Guide and mentor engineers, peer-review code, pipelines, models, transformations and documentation.

· Promote version control, testing, documentation, reusable components and agreed development practices.

· Work with platform, cloud, architecture, cyber security and information governance teams to meet requirements.

· Maintain documentation, metadata, data dictionaries, lineage and quality controls, and improve SWSDE standards, patterns and cloud capability.
