Role Overview: 1
Ab Initio lead:
We are seeking an experienced Ab Initio expert to lead and support the migration of legacy Ab Initio workloads to Azure Databricks. The candidate will serve as the onshore technical subject-matter expert, bridging business stakeholders and offshore delivery teams while ensuring data accuracy and delivery quality throughout the migration.
Scope of Engagement
· Migrate Ab Initio graphs and plans to Azure Databricks ETL jobs, covering assessment, conversion, validation, and help with Production.
· Translate Ab Initio logic into Databricks (Spark/PySpark/SQL) equivalents.
· Act as the onshore SME, partnering with business teams and translating requirements into clear specs for offshore delivery.
· Provide guidance, knowledge transfer, and data debugging support to offshore engineers.
· Support data validation during migration and help resolve source-side Ab Initio ETL execution issues.
· Flexible working hours to ensure effective overlap with offshore teams across time zones.
Roles & Responsibilities
Key Responsibilities
· Analyze and interpret existing Ab Initio graphs, plans, and components to document business and transformation logic.
· Translate complex Ab Initio functions (transform, rollup, join, partition/departition, lookup, normalize/denormalize, etc.) into target Databricks ETL designs.
· Partner with business teams to capture requirements and translate them into actionable specifications for offshore development teams.
· Provide technical guidance and knowledge transfer to offshore engineers executing the conversion.
· Lead data debugging, reconciliation, and root-cause analysis to resolve discrepancies between source (Ab Initio) and target (Databricks) outputs.
· Support data validation and reconciliation throughout the migration to ensure source-to-target parity.
· Troubleshoot and resolve source-side Ab Initio ETL execution issues to keep migration and validation on track.
· Define reusable conversion patterns, templates, and best practices to accelerate delivery.
· Support SIT/UAT cycles, validate data parity, and assist with performance tuning on Databricks.
Required Skills & Experience
· Strong hands-on expertise with Ab Initio (GDE, Co>Operating System, EME, Conduct>It plans, Continuous Flows).
· Deep understanding of Ab Initio graph design, components, and DML/transform functions.
· Working knowledge of Azure Databricks, Apache Spark, PySpark, and SQL.
· Proven experience in legacy ETL modernization or migration programs.
· Strong data analysis, validation, and debugging skills with the ability to trace logic across complex pipelines.
· Excellent communication skills to work across business stakeholders and distributed offshore teams.
Preferred Qualifications
· Experience migrating Ab Initio (or comparable legacy ETL such as Informatica/Teradata) to Databricks or other cloud lakehouse platforms.
· Familiarity with Azure data services (ADLS, ADF, Azure SQL) and CI/CD for data pipelines.
· Domain exposure to healthcare, banking, or other regulated, data-intensive industries.
· Experience leading or mentoring offshore delivery teams.
