Responsibilities

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)
Participate in code reviews, testing, documentation, and release activities; maintain clear runbooks and operational procedures
