• Write and optimize SQL queries across Oracle and SQL Server environments to troubleshoot data issues and validate results.

• Build, update, and maintain dashboards, reports, and Power BI deliverables that support business visibility and decision-making.

• Monitor ETL workflows, including SSIS-related processes, to identify failures, coordinate fixes, and improve data flow reliability.

• Produce clear technical documentation for support procedures, reporting logic, recurring issues, and resolution steps.

• Collaborate with cross-functional teams in Agile delivery settings, participating in planning, tracking, and continuous improvement activities using tools such as JIRA.

• Contribute to quality assurance efforts by validating outputs, testing changes, and helping maintain high data accuracy standards.

• Provide project-based support and take the lead on assigned initiatives when required, ensuring deadlines and service expectations are met.


• At least 5 years of experience in application support, data analysis, or a related data warehouse environment.
• Hands-on data warehouse experience is required.
• Minimum 4 years of experience using Python for scripting, automation, or data processing.
• Strong experience working with Oracle and SQL Server databases, including advanced query development and troubleshooting.
• Proven ability to create reports, dashboards, and data visualizations using Power BI and related Microsoft reporting tools.
• Solid understanding of ETL concepts and practical exposure to SSIS, SSRS, or similar data integration and reporting technologies.
• Demonstrated experience working within Agile methodologies, along with strong communication, documentation, problem-solving, and project coordination skills.
• Exposure to cloud platforms, AI frameworks or libraries, and QA practices would be considered an asset.
