The role will help maintain data quality and consistency across diverse health systems.

Responsibilities

• Assist in developing, reviewing, and maintaining diagnosis code lists and mappings (e.g., ICD-10, ICD-10 variants, SNOMED, MedDRA) used across GVDN projects.
• Ensure coding lists align with study-specific case definitions and international frameworks (e.g., Brighton Collaboration, GAIA).
• Support the design and refinement of diagnosis-code–based screening definitions, under the guidance of epidemiologists and clinical experts.
• Identify deprecated or ambiguous codes and recommend updates to reduce misclassification.
• Help harmonise code lists across projects while maintaining study-specific analytic intent.

• Familiarity with REDCap and data management workflows.
• Strong attention to detail and organisational skills.
• Ability to communicate clearly with multidisciplinary teams.
