Job Title: Senior C/C++ Linux Engineer
Location: Washington, D.C. (Onsite)
Duration: 12 months contract

Job description:
We are seeking a highly experienced C/C++ Linux engineer to design, modernize, and support real-time, fault-tolerant desktop applications. This role focuses on migrating legacy Motif/X11 GUI applications to modern Linux display protocols (Wayland) while ensuring high performance, security, and 24x7 system availability.

Key Responsibilities

• Design, develop, and maintain real-time, fault-tolerant Linux desktop applications using C and C++
• Migrate legacy GUI applications from Motif/X11 to modern frameworks such as GTK, Qt, or EFL on Wayland
• Optimize application performance using multithreading, memory management, and low-latency scheduling
• Debug and profile applications using gdb, valgrind, perf, and strace
• Develop and maintain Bash scripts for build automation, deployment, and system diagnostics
• Implement secure coding practices and support audit-readiness for mission-critical systems
• Build and maintain IPC mechanisms (sockets, shared memory, DBus)
• Configure and support lightweight desktop environments, custom window managers, and Wayland compositors
• Collaborate with cross-functional teams to integrate GUI applications with enterprise platforms and middleware
• Participate in code reviews, refactoring, and legacy system analysis
• Ensure 24x7 system availability and operational stability
• Create and maintain technical documentation including architecture diagrams, migration strategies, and operational procedures.

Required Deliverables

• Optimized Linux binaries and executables
• Well-structured C/C++ source code repositories
• Bash scripts for automation and diagnostics
• Build configurations using Make, CMake, or Meson
• Modernized GUI components migrated from Motif/X11
• Unit, integration, and performance test suites
• CI/CD pipeline configurations integrated with Bitbucket/Git
• Accessibility and compliance features (AT-SPI, keyboard navigation, screen readers)
• Legacy code refactoring and modernization reports.

Required Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or related field
• 10+ years of hands-on C/C++ development on Linux
• Strong expertise in Linux desktop application development and event-driven programming
• Experience with Motif, X11, and MWM, including legacy code refactoring
• Proficiency in Bash scripting
• Strong knowledge of Wayland architecture and GUI migration strategies
• Experience with Git/Bitbucket, branching strategies, and CI/CD pipelines
• Hands-on experience with CMake/Make and debugging tools (gdb, valgrind)
• Familiarity with OpenGL or Vulkan for rendering optimization.

Nice to Have

• Experience with custom Wayland compositors
• Exposure to high-availability or mission-critical systems
• Performance benchmarking for latency-sensitive applications
