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.

The ideal candidate is comfortable working in large legacy systems, diagnosing complex issues, and building modern service-based components that help evolve the system architecture over time.

Responsibilities:

• Maintain and enhance a large enterprise Windows desktop application written in native C++
• Understand and work effectively within a large legacy C++ codebase
• Debug complex production issues including:
• • memory leaks
  • race conditions
  • deadlocks
  • application crashes
• Perform crash dump analysis and runtime diagnostics
• Optimize memory usage, CPU performance, and concurrency
• Maintain and enhance Oracle database integrations
• Maintain existing SOAP-based integrations using Axis2/C
• Design and develop Java-based backend services using Spring / Spring Boot
• Gradually extract or migrate business logic from the desktop application into service-based components
• Design APIs that allow the legacy C++ system to interact with new services
• Troubleshoot and maintain build systems using Visual Studio and MSBuild
• Collaborate with QA, product management, DevOps, and architecture teams
• Conduct code reviews and enforce engineering best practices
• Contribute to incremental refactoring and modernization of legacy components

Qualifications:

8–12 years of software development experience, including strong experience with native C++ development and exposure to Java-based backend services using Spring or Spring Boot.
