Optimize application performance (startup time, UI rendering, memory usage) and ensure stability under real-world workloads.
Work on multi-threading, asynchronous programming, and inter-process communication where required.
Integrate third-party libraries, device/SDK interfaces, and platform-specific components (Windows/Linux; embedded a plus).
Write unit tests and automation tests (Qt Test, GoogleTest, QML test frameworks), ensuring code quality and maintainability.
Debug production issues, analyze crashes/logs, perform RCA, and implement preventive fixes.
Collaborate with product owners, UX designers, and backend teams to translate requirements into reliable, user-friendly features.
Maintain technical documentation, coding standards, CI build configurations, and participate in code reviews and change management routines.

Strong hands-on experience in C++ (C++11/14/17) with solid understanding of OOP, STL, memory management, and design patterns.
Excellent expertise in Qt framework (Qt Core, Qt Widgets, Qt Network, Qt Concurrent) and Qt Creator/CMake/qmake build systems.
Proven experience in QML/Qt Quick (Layouts, Controls, Animations, JavaScript in QML) and C++ QML integration.
Good understanding of multi-threading, synchronization, and thread-safe UI updates in Qt.
Strong debugging skills using GDB/LLDB/Visual Studio Debugger, profilers, and performance tools.
Experience with version control (Git) and CI/CD pipelines for builds/tests (Jenkins/GitLab CI/Azure DevOps).
Working knowledge of networking fundamentals and Qt networking APIs (HTTP/WebSockets/TCP/UDP as applicable).
