About the role

  • Design, develop, and maintain IBM DataStage ETL jobs that ingest file feeds (CSV, fixed-width, delimited) and load curated destination tables in SQL Server.
  • Build end-to-end ETL flows, including staging, transformations, validations, and publishing to downstream schemas.
  • Perform source-to-target mapping and implement transformation logic based on business and technical requirements.
  • Use common DataStage stages and patterns (e.g., Sequential File, Transformer, Lookup, Join/Merge, Aggregator, Sort, Funnel, Remove Duplicates), with attention to partitioning and parallel job design.
  • Write, optimize, and tune SQL Server queries, stored procedures, and T?SQL scripts used in ETL workflows.
  • Implement restartable and supportable jobs: parameterization, robust logging, reject handling, auditing columns, and reconciliation checks.
  • Apply data quality controls (format checks, referential checks, null/duplicate checks, threshold checks) and produce clear exception outputs for remediation.
  • Monitor and troubleshoot ETL runs using DataStage Director/Operations Console and SQL Server tooling; perform root-cause analysis and fix defects.
  • Improve performance through job design tuning (partitioning strategy, sorting choices, buffering, pushdown where appropriate) and SQL tuning (indexes, statistics, set-based logic).

Requirements

  • Hands-on IBM DataStage ETL development experience, including data mapping and transformation implementation.
  • Strong SQL Server experience with advanced T?SQL (joins, window functions, CTEs, temp tables, indexing basics, query plans).
  • Solid understanding of file-based ingestion and parsing (CSV, fixed-width, headers/trailers, control totals, encoding, delimiters, quoting/escaping).
  • Experience designing ETL jobs with good operational characteristics: parameter-driven design, logging, error handling, restart/re-run strategy, and auditability.
  • Ability to troubleshoot data issues end-to-end (source file – stage tables – target tables) and communicate findings clearly.
