Focusing on our Sportsbook product, we’re looking for a Data Quality Engineer to help ensure the reliability, accuracy, and trustworthiness of data across our next-generation data platform, supporting multiple brands and markets.

You’ll work on our Sportsbook Data Platform — a modern, event-driven lakehouse built on AWS and aligned to medallion architecture principles — embedding data quality, observability, and governance into the core of our data ecosystem. This role is critical in ensuring that data powering analytics, trading insight, and machine learning is consistent, well-understood, and fit for purpose.

What You’ll Do

• Design and implement scalable data quality frameworks across batch and streaming pipelines.
• Define and enforce data quality rules, including completeness, accuracy, consistency, timeliness, and validity.
• Build automated data validation checks within ingestion and transformation pipelines (e.g. dbt tests, custom frameworks with Soda).
• Develop monitoring and observability capabilities to detect anomalies, data drift, and pipeline failures.
• Implement alerting mechanisms to surface data quality issues to relevant stakeholders in a timely manner.
• Partner with data engineers to embed quality controls within medallion layers (bronze, silver, gold).
• Define and maintain data contracts and schema validation to ensure reliability between producers and consumers.
• Perform root cause analysis of data issues and work with upstream and downstream teams to resolve them.
• Establish and track data quality SLAs/SLOs and report on data health metrics.
• Contribute to metadata management, including data lineage, definitions, and quality annotations.
• Support governance initiatives to improve data trust, discoverability, and standardisation across the platform.

What You’ll Work On

• A modern sportsbook data platform built on AWS, supporting both real-time and batch processing.
• Data quality frameworks embedded across medallion architecture layers.
• Monitoring and observability tooling for data pipelines and datasets.
• High-volume streaming and batch datasets covering bets, pricing, settlements, and customer activity.
• Integration with metadata platforms to provide visibility into lineage, ownership, and quality metrics.
• Cross-team workflows to manage and resolve data incidents and improve data reliability.

Your Experience

• 3+ years experience in data engineering, data quality, or a related field.
• Strong SQL skills and experience working with large-scale datasets.
• Experience implementing data quality checks and validation frameworks (e.g. dbt tests, Soda, or similar).
• Familiarity with data pipeline orchestration and transformation tools (e.g. Airflow, Spark, dbt).
• Experience with cloud-based data platforms, ideally AWS.
• Understanding of data modelling and data lifecycle concepts.
• Experience with data observability, monitoring, and alerting practices.
• Ability to investigate and resolve data issues across distributed systems.
• Strong attention to detail and a proactive approach to improving data reliability.
• Ability to collaborate with engineers, analysts, and business stakeholders.

Nice to Have

• Experience in sports betting, trading, or financial data domains.
• Familiarity with streaming data quality challenges (e.g. late data, duplication, ordering).
• Experience with observability tools (e.g. Soda, Great Expectations, or similar).
• Exposure to metadata and governance tooling (e.g. OpenMetadata, Hive Metastore).
• Understanding of data contracts and schema evolution practices.
• Experience supporting machine learning or analytics data quality requirements.

Why This Role Matters

Data quality is foundational to how we operate our sportsbook. This role ensures that the data powering trading decisions, analytics, and machine learning is accurate, reliable, and trusted. By embedding quality and observability into the platform, you’ll help reduce risk, improve decision-making, and enable teams across the business to confidently rely on data at scale.

We believe talent knows no boundaries. Our hiring process focuses solely on your skills, experience, and potential to contribute to our team.
