Your Role

You will support a major database migration project from SAP HANA to PostgreSQL in a high-security IT environment.

Your main responsibilities will include:

• Analyze existing SAP HANA database structures, views, procedures, and SQLScript logic
• Design and implement PostgreSQL schemas, tables, views, functions, and stored procedures
• Support the migration of database logic from SAP HANA / SQLScript to PostgreSQL / PL/pgSQL
• Develop and test migration scripts, data transformation logic, and validation routines
• Optimize SQL queries, indexes, and PostgreSQL database performance
• Document technical decisions and migration steps clearly and reliably

Your Tech Stack & Experience

You should have solid experience in database development and migration projects, particularly in several of the following areas:

• Extensive experience with SQL and PostgreSQL
• PL/pgSQL, stored procedures, functions, triggers, or similar database-side programming
• Database design, data modeling, schema development, and performance tuning
• Data migration, ETL, transformation logic, and data validation
• Linux-based environments and Git or comparable version control systems
• Experience with reporting solutions, preferably based on open-source tools

Experience with the following would be a strong plus:

• SAP HANA, SAP HANA SQL, SQLScript, calculation views, or generated SAP HANA views
• Migration from SAP HANA, Oracle, SQL Server, DB2, or other enterprise databases to PostgreSQL
• Proxmox or virtualized infrastructure environments
• High-security, regulated, public-sector, aerospace, defense, or mission-critical IT environments
