  • Collaboration & Engagement: Work with Data Engineers, Platform Engineers, Product Owners, Business SMEs, and third-party partners to ensure connected technical testing solutions; review implemented Unit tests for data processing applications.

Qualifications

  • Experience in data engineering testing; strong knowledge of AWS data pipelines, Data Warehouse, Data Lakehouse, ETL/ELT processes, data quality concepts, and related testing methodologies.
  • Experience building advanced test automation frameworks from scratch using object-oriented and scripted languages; breadth across different tech stacks.
  • Proficiency in Java Script/Type Script, Java, C#, Python (two or more); strong understanding of object-oriented programming.
  • Experience in AWS cloud services (AWS Glue), Python/Py Spark, SQL, YAML configurations, and CI/CD tools (Git Hub Actions or similar).
  • Knowledge of AI-driven testing solutions and automation accelerators; solid understanding of data feeds architectures and best practices.
  • Strong problem-solving, data quality, defect management, and reporting skills (e. g., JIRA, XRAY, ADO); API/interface testing is a plus.
  • Non-functional testing experience and AWS fundamentals; AWS Certified Data Engineer is a plus; familiarity with HDFS.
