Job description

Track 1 – Database Migration (Backbone/Backend)

This track covers the migration of the legacy Sybase database environment to a modern SQL-based platform. The focus is not traditional infrastructure DBA work, but rather application-level database development — specifically, deep analysis of existing Sybase stored procedures, understanding the embedded business logic within them, and re-engineering or converting that logic to function correctly in the target database environment. Vendor staff will work closely with internal leads who oversee data migration pipelines and stored procedure logic to ensure accuracy, performance, and functional parity throughout the migration waves.

Position 1: Application DBA / Stored Procedure Developer

Key responsibilities include analysing and documenting existing Sybase stored procedures to understand embedded business and application logic, re-engineering or converting stored procedures to T-SQL or the target platform's equivalent, validating that converted logic produces functionally equivalent outputs, collaborating with application developers to resolve logic dependencies between the database layer and application code, supporting schema migration and data integrity validation, and participating in migration wave testing and cutover activities.

Requirements:

Minimum 3 years of experience in application-level database development or stored procedure engineering

Strong expertise in Sybase stored procedures and database architecture

Proficiency in T-SQL or equivalent target platform SQL dialect

Ability to read, interpret, and re-engineer complex business logic embedded in database procedures

Experience with database migration projects, including schema conversion and functional validation

Familiarity with ETL pipelines and data migration methodologies is an advantage
