The role is responsible for validating migrated data pipelines, performing source-to-target reconciliation, identifying root causes of data discrepancies, and partnering with development teams to accelerate defect resolution.\nThe ideal candidate should possess strong expertise in DBT, Snowflake, ETL/Data Warehouse concepts, SQL-based reconciliation, and legacy Informatica workflows, with the ability to independently analyze complex data issues and provide actionable defect diagnostics.\nRoles & Responsibilities:\nData Validation & SIT Support\nPerform end-to-end source-to-target data validation across Informatica and DBT-based implementations.\nValidate data completeness, accuracy, transformations, aggregations, and business rules across staging, core, and mart layers.\nExecute record count, aggregate, reconciliation, SCD, and incremental-load validation.\nAnalyze data discrepancies and identify root causes before routing defects to development teams.\nPrepare SQL evidence, impacted records, and detailed defect diagnostics to improve defect quality and reduce turnaround time.\nParticipate in SIT defect triage sessions and collaborate with development teams to accelerate issue resolution.\nValidate data lineage and trace data flow across source systems, DBT models, and Snowflake objects.\nDBT & Data Engineering Support\nTranslate Informatica mappings, transformations, and business rules into DBT models where required.\nDevelop and maintain DBT tests (schema tests, custom tests, data-quality validations).\nDesign and implement staging, core, and mart layers using DBT best practices.\nParticipate in performance analysis and optimization of DBT models and Snowflake queries.\nSupport deployment validation and migration activities across environments.\nQuality & Governance\nContribute to SIT strategy, test case reviews, and validation frameworks.\nEnsure defects are documented with clear root-cause analysis, business impact, and remediation recommendations.\nSupport regression testing and release validation activities.\nMaintain validation documentation, reconciliation reports, and testing evidence.\nExperience & Skills\n7+ years of experience in Data Warehouse, ETL, Data Engineering, or Data Validation.\n2+ years of hands-on experience with DBT (Core or Cloud).\nStrong experience in Data Warehouse Migration / Modernization programs.\nExperience supporting SIT or large-scale data validation initiatives.\nDeveloper-level understanding of Informatica mappings, workflows, and transformations.\nExperience working with Snowflake and modern cloud data platforms.\nGood communication skills and ability to read/understand existing ETL logic and requirements documentation.\nMust Have:\n1) Strong Knowledge of\nAdvanced
