• Contribute to CI/CD pipelines and Git-based workflows
• Troubleshoot and optimise data pipelines for reliability and performance

Required Experience

• Strong Data Engineering background
• Advanced Python and SQL skills
• Experience with PySpark or distributed processing tools
• Proven track record building reusable data frameworks
• Strong testing experience (pytest, mock data, data validation techniques)
• Solid understanding of data quality, integrity, and pipeline behaviour
• Experience with CI/CD, Git, and code review processes

Desirable

• Experience in enterprise or cloud-based data environments
• Exposure to dbt, Great Expectations, or similar tools
• Experience in retail, hospitality, or customer-focused industries
