We are looking for an experienced Informatica Cloud Data Integration (CDI) Engineer to join our data modernization initiative. In this role, you will be instrumental in migrating legacy, mission-critical SAS data workflows, scripts, and business logic onto modern cloud-native architectures using Informatica Intelligent Cloud Services (IICS) CDI.

You will lead the end-to-end design, implementation, and optimization of cloud-based data ingestion and transformation pipelines, ensuring seamless business continuity and data fidelity.

Responsibilities

Pipeline Architecture & Design (CDI)

  • ● Architect, design, develop, and deploy robust, scalable ELT/ETL pipelines using Informatica Cloud Data Integration (CDI).
  • ● Design modular data integration components, including complex Data Synchronization Tasks, Mapping Tasks (MCTs), and Taskflows.
  • ● Build low-latency, scalable pipelines connecting diverse sources to enterprise cloud data warehouses/lakes (e.g., Snowflake, BigQuery, AWS Redshift, or Databricks).
  • ● Establish best practices for parameterization, dynamic configuration, error handling, session logging, and alerting in IICS CDI.

SAS Migration & Modernization

  • ● Conduct thorough analysis of legacy SAS scripts, macros, data steps, and SQL procedures (PROC SQL, DATA steps, hash objects) to extract and document business rules.
  • ● Reverse-engineer legacy SAS logic into target data models and transformational logic in CDI and SQL.
  • ● Design parallel-run execution strategies, reconciliation pipelines, and regression testing frameworks to validate numerical and structural parity between SAS outputs and CDI outputs.
  • ● Decommission obsolete SAS workflows, identifying consolidation and performance optimization opportunities.

Performance Optimization & Governance

  • ● Optimize CDI mappings and pushdown optimization (Full/Source pushdown) to maximize processing efficiency on cloud warehouses.
  • ● Manage IICS Secure Agents, runtime environments, and scheduling integration (e.g., Control-M, Autosys, or Cloud Native Schedulers).
  • ● Partner with Data Governance, Security, and Quality teams to implement data masking, lineage tracking, and compliance standards.

Requirements

  • ● Informatica Cloud Data Integration (CDI): 4+ years of hands-on experience building complex mappings, hierarchical transformations, lookups, and taskflows in IICS CDI.
  • ● SAS Modernization / Translation: 2+ years of direct experience analyzing, modernizing, or re-platforming legacy Base SAS / SAS MACRO workflows. Ability to read SAS code fluently and reconstruct its logic using modern SQL/CDI.
  • ● SQL & Data Warehousing: Advanced SQL proficiency (complex analytical functions, windowing, subqueries) with hands-on experience in at least one modern cloud warehouse (Snowflake, AWS Redshift, Google Cloud BigQuery, or Azure Synapse/Databricks).
  • ● Data Modeling: Solid understanding of Star Schema, Snowflake Schema, SCD (Slowly Changing Dimensions Types 1, 2, 3), and data staging patterns.
  • ● End-to-End Delivery: Proven record of participating in large-scale data re-platforming, validation, and historical data reconciliation.
  • ● Strong analytical problem-solving skills with meticulous attention to detail in data validation and discrepancy resolution.
  • ● Ability to articulate technical trade-offs between pushdown SQL execution and CDI transformations to technical and non-technical stakeholders.
  • ● Experience mentoring mid-level/junior engineers and conducting code/design reviews.
  • ● Education: Bachelor’s or Master’s degree in Computer Science, Information Technology, Data Engineering, or a related quantitative field (or equivalent practical experience).
  • ● Experience: 6+ years of overall data engineering/integration experience, with a proven focus on IICS CDI implementations and legacy ETL/code migrations.

Preferred

  • ● Official Informatica Cloud Data Integration Specialist Certification.
  • ● Hands-on scripting capability in Python or Bash for pipeline automation and validation.
  • ● Familiarity with CI/CD deployment pipelines for IICS artifacts (Git integration, asset export/import APIs).
  • ● Experience handling semi-structured data formats (JSON, Parquet, Avro, XML) within CDI.
