• Partner with developers to improve testability and system observability
• Support rapid feedback loops that reduce rework and deployment risk

• Act as a quality coach within the team, influencing design and delivery decisions

• Strong experience in automated testing using Python and SQL
• Deep understanding of data pipelines, ETL, and analytics platforms
• Experience testing APIs and distributed systems
• Comfortable working with CI/CD pipelines and Dev Ops tooling
• Analytical mindset with a focus on prevention over detection
