Senior Data QA Developer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Data QA Developer based in Canada.

This is a senior engineering role focused on ensuring the integrity, reliability, and scalability of modern data platforms. You’ll design and build automated quality frameworks that validate complex pipelines, transformations, schemas, and datasets. Working closely with data engineers and product stakeholders, you’ll help embed quality controls early in the development lifecycle. You’ll work hands-on with Python, SQL, BigQuery, Airflow, and modern CI/CD practices to create dependable data products. The role offers significant ownership in a fast-moving, technology-driven environment where engineering quality directly impacts business-critical analytics. It’s an opportunity to help establish data quality standards and build resilient infrastructure within a high-growth organization.

Accountabilities:: Design and architect robust, automated data quality frameworks and testing suites using Python and SQL to validate data integrity, schema consistency, transformation logic, and pipeline behavior.

Partner with Data Developers and Product Managers during solution design to establish data contracts, quality gates, acceptance criteria, and testing strategies before implementation begins.

Develop automated data-SLA monitoring and observability capabilities to identify anomalies and data quality issues across BigQuery, Airflow, and downstream systems.

Perform detailed validation of complex ELT/ETL processes, ensuring datasets are accurate, secure, reliable, and optimized for analytics and reporting workloads.

Integrate data-specific automated testing and regression checks into Git-based CI/CD pipelines and infrastructure-as-code workflows.

Investigate data defects, pipeline failures, anomalies, and SQL performance issues, identifying root causes and implementing durable solutions.

Collaborate with engineering teams to improve data modeling, documentation, governance, development workflows, and overall quality standards.

Contribute to continuous improvement initiatives that make data development, deployment, monitoring, and validation more efficient and reliable.

Help establish scalable QA practices and technical standards that support the growth of a modern cloud-based data platform.
