Senior DataStage Consultant
Orlando, FL Hybrid 3-Days onsite Need Local
Long Term
Contract
• 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.
• Collaborate with business analysts, data modelers, QA, and production support to deliver stable pipelines.
Required skills and experience
• 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.
Preferred qualifications
• Experience with DataStage Parallel Jobs tuning (partitioning methods, collect/sort trade-offs, skew handling).
• Familiarity with UNIX/Linux basics and shell scripting for orchestration and file handling.
• Experience with job scheduling/orchestration tools (e.g., Control M, Autosys) and CI/CD practices.
• Knowledge of common warehousing patterns (incremental loads, slowly changing dimensions, surrogate keys, effective dating).
• Experience with version control (Git) and structured promotion/release processes across environments (dev/test/prod).
• Exposure to data governance practices (metadata, lineage, naming standards) and secure handling of sensitive data.
Education
• Bachelor’s degree in Computer Science, Engineering, Information Systems, or equivalent practical experience.
What success looks like in this role
• File feeds land and load consistently with clear reconciliation results.
• Failures are diagnosable from logs and reject outputs without deep forensics.
• Jobs meet runtime SLAs through solid DataStage design and SQL tuning.
• Mappings and transformations are documented and traceable to requirements.
