We are seeking a highly skilled Senior C/C++ Linux Engineer to support a mission-critical modernization initiative for a client in Philadelphia, PA. This role involves upgrading legacy Linux-based desktop applications by migrating them from outdated GUI frameworks (Motif/X11) to modern solutions like Wayland and GTK/Qt. The engineer will be responsible for building high-performance, real-time software with a focus on reliability, security, and low-latency responsiveness. This position is essential to platform stability, operational continuity, and long-term technology resilience.

- Write Bash scripts for build automation, deployment routines, and system diagnostics
- Optimize application performance using multithreading, memory management, and scheduling techniques
- Debug and profile applications with tools like gdb, valgrind, perf, and strace
- Implement secure coding practices and support audit-readiness for critical systems
- Integrate GUI applications with enterprise middleware and backend services
- Configure and maintain lightweight Linux desktop environments and custom window managers
- Manage source code and CI/CD workflows using Git and Bitbucket
- Develop and support IPC mechanisms (sockets, shared memory, DBus) for inter-process communication
- Support containerized deployments using Docker in secure environments
- Document system architecture, migration plans, and operational procedures
Qualifications:
- Bachelor’s degree in Computer Science, Software Engineering, or a related field (required)
- 10+ years of hands-on experience in C/C++ development on Linux systems
- Expertise in event-driven programming and development of Linux desktop applications
- Experience modernizing GUI applications from Motif/X11 to GTK, Qt, or Wayland
- Proficiency in Bash scripting and build systems like Make, CMake, and Meson
- Familiarity with Wayland protocols and compositor-client architecture
- Experience with Git-based version control and CI/CD pipelines (Bitbucket, GitLab, etc.)
- Strong understanding of Linux system internals, IPC, and GUI performance tuning
- Exposure to low-level graphics APIs such as OpenGL or Vulkan (preferred)
- Ability to develop custom Wayland protocols and implement IPC optimizations via shared memory (preferred)
- Excellent documentation and communication skills
