Job Description
We have developed a Qt-based embedded application that is deployed as a standalone, dedicated OS using Yocto Project. The system boots directly into the Qt application (no desktop environment), and is intended to behave like an independent appliance-style OS. However, we are facing critical performance and stability issues in the current Yocto build that need to be diagnosed and fixed by an experienced Yocto engineer.. Current System Overview Custom Yocto image Qt-based GUI application Direct boot into Qt application (no X11 desktop) Touchscreen-based embedded device Hardware-specific BSP already available Image is booting and functional, but not production-ready What We Expect From You Analyze the Yocto configuration (layers, recipes, local.conf, kernel config) Debug Qt performance issues on embedded Linux Optimize Qt, kernel, and system services Ensure stable, responsive UI behavior Suggest best practices for production-grade Yocto images Clearly explain root cause + applied fixes
Required Skills Strong experience with Yocto Project Embedded Linux system optimization Qt (Qt Widgets / Qt Quick) on embedded devices Kernel configuration & device drivers (touchscreen, input) Performance debugging on low-resource systems Experience with production embedded products (not demos) Nice to Have Experience with Buildroot vs Yocto comparison Qt boot-to-app optimization Systemd service tuning Touchscreen driver tuning (EVDEV, tslib, libinput) Project Type Short-term debugging & optimization Possibility of long-term collaboration if work quality is good Apply tot his job
