We are seeking a Senior Data Engineer to design and build scalable data solutions that harmonize enterprise data across multiple ERP ecosystems
. This role focuses on integrating and standardizing data from SAP (ECC/S4

HANA), Oracle ERP, SaaS ERP platforms (such as Net Suite), and other enterprise systems into unified data models.

The engineer will collaborate closely with ERP functional teams, Functional Data Experts (FDEs), and product engineers to translate complex business logic into robust data transformation pipelines and canonical enterprise data models
.

This role requires strong experience in SQL, Python, enterprise data modeling, and ERP data structures
, combined with the ability to solve complex cross-system data inconsistencies and harmonization challenges
.

Enterprise organizations often operate across multiple ERP systems and business platforms
, each with different schemas, definitions, and data semantics. Without proper harmonization, data becomes fragmented and unreliable for operations, analytics, and decision-making.

This role is critical in building the data foundation that enables organizations to operate with consistent, trusted enterprise data across systems.

• Design and develop scalable ETL/ELT pipelines to ingest and transform data from enterprise systems including:
  • SAP ECC / S4
    
    HANA
  • Oracle ERP / Oracle Fusion
  • SaaS ERP platforms such as Net Suite
  • Legacy ERP and adjacent enterprise systems
• Implement transformation pipelines using SQL and Python.

  • relational data platforms
  • dimensional analytics models
  • enterprise semantic layers.

• Work closely with ERP functional teams and Functional Data Experts (FDEs) to translate business rules into technical implementations.
• Convert functional requirements into:
  • SQL transformation logic
  • Python-based processing pipelines
  • validation and reconciliation frameworks.

• Implement data validation, reconciliation, and monitoring frameworks.
• Identify and resolve enterprise data issues such as:
  • duplicate master data
  • inconsistent definitions across ERP systems
  • incomplete or legacy datasets
  • configuration-driven inconsistencies.

• 5–8+ years of experience in Data Engineering, Data Integration, or Data Platform development
• Experience working with enterprise ERP systems, such as:
• SAP (ECC or S/4
  
  HANA)
• Oracle ERP / Oracle Fusion
• Net Suite or other SaaS ERPs
• Experience supporting ERP transformation, migration, or multi-system integration initiatives.

• Advanced SQL
• Strong Python for data engineering workflows and pipeline development

• Experience building ETL/ELT pipelines
• Experience processing large-scale enterprise datasets
• Familiarity with modern data architectures and distributed processing

• Strong understanding of:
  • relational data models
  • dimensional models
  • canonical enterprise data models

• General Ledger
• Accounts Payable / Receivable
• Financial transactions

• Materials and product data
• Procurement and vendor management
• Inventory and logistics
