• Troubleshoot data pipeline issues, production defects, and integration failures.
• Follow engineering standards for code quality, CI/CD, documentation, security, and operational readiness.

• 6+ years of experience in data engineering, ETL development, ML engineering, analytics engineering, or software engineering.

• Experience working with data integration or ETL tools such as AWS Glue, Qlik Data Integration, Snowflake, or similar platforms.
• Familiarity with AWS services such as S3, Glue, Lambda, SageMaker, CloudWatch, or related cloud services.
• Understanding of data modeling, data quality, orchestration, metadata, and pipeline monitoring.
• Exposure to machine learning workflows, feature engineering, batch scoring, or model deployment support.
• Experience working with structured and semi-structured data.
• Familiarity with Git, CI/CD pipelines, automated testing, and Agile delivery practices.
• Strong problem-solving skills and ability to troubleshoot pipeline and data issues.
• Ability to collaborate effectively with engineering, data science, product, and business teams.
• Bachelor’s degree in Computer Science, Information Technology, Information Systems, or a related field (or equivalent industry experience).

• Experience supporting offer optimization, personalization, recommendation, customer insights, onboarding, or digital acquisition platforms.
• Exposure to MLOps practices, model registries, feature stores, batch scoring, or model monitoring.
• Experience with CDC, event-driven integration, or near-real-time data movement.
• Experience working with merchant, customer, application, product, or transaction data.
