• Hands-on experience with C, C++ (11/14), Python, and TCL programming languages.
• Experience with concurrent programming, multithreaded, and multi-process systems.
• Strong understanding of firmware architecture, software design patterns, and scalable embedded software design.
• Experience developing Qt/QML user interfaces.
• Hands-on experience with HTTP/REST APIs and secure web services.
• Good knowledge of Assembly (when required), RTOS concepts, and embedded systems development.
• Strong experience working in Linux (embedded and development environments), Windows, and macOS.
• Experience with Git/GitHub version control systems.
