Job Description

Key Responsibilities

• Perform end-to-end ETL testing, including source-to-target data validation, reconciliation, and transformation checks across multiple stages of the pipeline.

• Write and execute complex SQL queries for backend data validation.

• Create detailed test plans, test scenarios, and test cases/scripts based on mapping documents, user stories, and business requirements.

• Design and run reconciliation checks between legacy, staging, target databases, and reporting layers.

• Validate data correctness in target applications to ensure migrated/loaded data supports key business scenarios.

• Log, track, and manage defects to closure using tools such as Jira, including clear steps, SQL evidence, and impact analysis.

• Provide daily/regular test execution and status reports to stakeholders, highlighting progress, defect trends, and risks.

• Collaborate effectively with cross-functional teams (data engineers, migration developers, functional QA, BAs, architects, and customer SMEs) to ensure data quality and timely delivery.

• Contribute to and maintain reusable SQL libraries, reconciliation templates, and best-practice checklists for data testing across projects.

• Mentor junior QAs new to data testing on SQL, reconciliation techniques, and Guidewire data migration concepts; contribute to reusable data-QA accelerators for PS.

Required Experience

• 6–8 years of overall QA / testing experience, with at least 3–4 years focused on data testing or data migration in enterprise systems.

• Strong SQL skills (joins, aggregations, reconciliation queries) and experience validating large datasets across multiple databases or stages.

• Hands-on experience in at least one of:

  • Data migration to core policy/claims/billing systems, or

  • ETL/ELT and data warehousing / data lake testing.

• Familiarity with Guidewire InsuranceSuite data models and migration tooling.

• Proven experience designing data test strategies, authoring detailed test cases, and executing reconciliation/NFR tests across multiple dry runs.

• Strong defect investigation skills: able to isolate issues using SQL, mapping documents, and logs, and articulate root causes and business impact.

• Comfortable working in Agile/Scrum delivery with distributed teams (data engineers, migration developers, functional QA, architects, customer SMEs).

• Good communication skills and ability to manage own workload, priorities, and timelines.

Nice to Have

• Experience on Guidewire based data migration projects (InsuranceSuite cloud or on-prem) or similar core system transformations.

• Exposure to cloud data platforms (e.g., AWS, Azure, Fabric/OneLake, Snowflake) and associated ETL/ELT tools.

• Experience with analytics and BI tools such as Power BI or Fabric and with Guidewire data tooling such as Data Studio and Explore, for validating downstream datasets, reports and KPIs.
