Senior Software EngineerEPAM Systems

We are seeking a highly analytical and data-focused Senior Software Engineer to play a pivotal role in our upcoming platform migration.

This is a high-impact, data-intensive role requiring deep expertise in relational databases (Microsoft SQL Server and Sybase), complex data transformation, and meticulous data validation.
