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 bring solid experience in database development and migration projects, especially in several of the following areas:

• Strong SQL and PostgreSQL experience
• PL/pgSQL, stored procedures, functions, triggers, or comparable database-side programming
• Database design, data modelling, 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

A strong plus would be experience with:

• 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

We are looking for experienced database professionals who understand that migration is not only about moving data, but also about preserving logic, performance, reliability, and business-critical functionality.

You are a good fit if you:

• Have a strong database engineering mindset

• Work carefully, independently, and with a strong sense of responsibility
• Communicate clearly with technical stakeholders
• Are willing to work on-site due to project security requirements
• Are eligible to work in a high-security project environment
