Overview:
We are looking for a Senior Software Engineer to maintain, enhance, and progressively modernize a large enterprise Windows desktop application built in native C++.
The current system includes UI components, backend business logic, Oracle database integrations, and SOAP-based service integrations (Axis2/C). The application has evolved over several years and contains a complex legacy codebase requiring strong debugging skills and architectural understanding.
In addition to maintaining the existing C++ system, this role will contribute to modernization initiatives by designing and developing Java-based backend services using Spring / Spring Boot, enabling gradual migration of business logic from the legacy application into scalable service-based components.
