• Exceptional attention to detail, with a demonstrated commitment to ensuring data accuracy, completeness, and consistency
• Strong communication skills, capable of clearly conveying data issues, processes, and insights to both technical and non-technical teams
• A degree in a quantitative subject
  
  
  

Good if you also have:

• A genuine passion for cricket
• Previous experience in a role focused on data quality, or data analysis
• A working knowledge of basic statistics or machine learning concepts, particularly as they apply to data validation or modeling workflows
