Job description
5 DAYS ONSITE
- Design, develop, and maintain real-time, fault-tolerant desktop applications using C and C++ on Linux platforms
- Migrate legacy GUI applications from Motif/X11 environments to modern Linux display protocols such as Wayland, using toolkits like GTK, Qt, or EFL
- Write and maintain Bash scripts to automate build processes, deployment routines, and system-level diagnostics
- Optimize application performance through multithreading, memory management, and low-latency scheduling techniques
- Debug and profile applications using tools such as gdb, valgrind, perf, and strace to ensure stability and responsiveness
- Implement secure coding practices and support audit-readiness for mission-critical systems
- Collaborate with cross-functional teams to integrate GUI applications with enterprise platforms and middleware
- Configure and support lightweight desktop environments and custom window managers, including MWM and Wayland compositors
- Manage source code and development workflows using Bitbucket, Git, and CI/CD pipelines
- Develop and maintain IPC mechanisms (e.g., sockets, shared memory, DBus) for inter-process communication
- Document system architecture, migration strategies, and operational procedures for modernization initiatives
- Participate in code reviews, refactoring efforts, and legacy system analysis to support long-term maintainability
- Support containerized deployment of desktop applications using Docker in secure, isolated environments
