• Implement data quality checks, reconciliation logic, validation rules, and observability mechanisms to ensure confidence in enterprise data products.  
• Support governance requirements through traceable transformation logic, documentation, lineage awareness, and adherence to platform and enterprise standards.  
• Collaborate with security, infrastructure, and operations teams to support compliant, secure, and reliable deployment of data solutions in a regulated environment.  
• Write clean, maintainable, and well-documented code following team standards for version control, peer review, testing, and deployment.  
• Participate in unit testing, integration testing, debugging, and continuous improvement across pipeline and data product components.  
• Leverage modern engineering tools, including AI-assisted development tools where appropriate, to improve productivity, quality, and consistency.  
• Participate in agile ceremonies such as sprint planning, backlog refinement, daily standups, demos, and retrospectives.
