We are looking for a Senior or Mid Software Engineer to join our R&D team and take ownership of existing device programming tools used in automotive environments. A key aspect of this role is experience with device communication or firmware programming tools, as the software directly interacts with hardware devices for firmware flashing, updating, and configuration.
The main goal of this position is to take over and modernize existing device programming tools (“loaders”) originally developed in Delphi 7, migrating them to the C# / .NET platform. These applications are used to program, update, and configure automotive device firmware while ensuring reliable communication with devices through various interfaces. The objective is to build a clear, maintainable, and scalable architecture suitable for long-term development.
