Your Responsibilities

Data Quality & Validation

• Design and implement data validation frameworks to ensure accuracy and consistency across ingestion, transformation, and reporting layers.
• Validate data transformations between OLTP and OLAP systems, including schema, logic, and aggregation correctness.
• Execute end-to-end testing of data pipelines, from raw data ingestion through downstream reporting outputs.
• Develop automated data quality checks to detect anomalies, breakages, and data drift.

Testing & QA Process

• Define and maintain test plans and detailed test cases tied to specific data workflows and use cases.
• Document validation logic, QA processes and testing methodologies for repeatability and auditability.
• Establish standards for data quality metrics and acceptance criteria across datasets and reporting outputs.

Issue Resolution & Cross-Functional Work

• Investigate data discrepancies, perform root cause analysis and resolve pipeline or transformation issues.
• Partner with Data Engineering, Analytics, and Product teams to align on data definitions, transformations and validation requirements.
• Validate client‑facing dashboards, reports and analytical outputs against source data and business logic.
• Support validation of campaign performance data, reporting outputs, and QBR deliverables.

Your Qualifications

• Bachelor’s or Master’s degree in Computer Science, Data Analytics, Statistics, Mathematics or a related quantitative field.
• 3+ years of experience in data QA, data analytics or data engineering support roles with hands‑on responsibility for validating production datasets.
• Advanced SQL skills used for data validation, reconciliation and anomaly detection across large datasets.
• Experience testing data pipelines and transformations across multiple layers (ingestion, ETL/ELT, reporting).
• Experience validating BI dashboards and reports (e.g., "Tableau"), including metric definitions and data consistency.
• Experience building or maintaining automated data quality checks using Python or similar scripting languages.
• Working knowledge of data modeling concepts, including differences between OLTP and OLAP systems.
• Experience working with large‑scale datasets in cloud data environments (e.g., Redshift, Hive, EMR or equivalent).
• Experience investigating and resolving data issues through structured root cause analysis.

Preferred Qualifications

• Experience working with transaction‑level datasets (e.g., credit/debit card data), loyalty data or consumer purchase data.
• Experience validating marketing analytics, campaign performance data or programmatic advertising datasets.
• Familiarity with data quality frameworks, monitoring tools or testing methodologies used in production data environments.
