You will work closely with cross-functional teams including system architects, QA, and hardware engineers to build robust and scalable system-level solutions.

Responsibilities

Core Development

• Design, develop, and maintain software components in C for both:
• Kernel space (Linux kernel modules, drivers, subsystems)
• User space applications, daemons, and system services
• Implement high-performance and low-latency solutions with attention to memory and CPU efficiency
• Develop and maintain device drivers, kernel modules, and system-level interfaces
  

System-Level Engineering

• Work with Linux internals (process scheduling, memory management, IPC, networking stack)
• Debug complex issues across kernel and user space boundaries
• Analyze system performance and implement optimizations
  
  

Debugging & Troubleshooting

• Investigate and resolve issues using tools such as:
• gdb, strace, perf, ftrace
• Kernel crash dumps (kdump, crash tool)
• Root cause analysis for system crashes, memory leaks, and race conditions
  

Integration & Collaboration

• Collaborate with hardware teams for driver development and bring-up
• Work with DevOps and QA to integrate solutions into CI/CD pipelines
• Participate in design reviews and contribute to architectural decisions
  
  

Code Quality & Security

• Write clean, maintainable, and well-documented code
• Ensure adherence to coding standards (e.g. Linux kernel guidelines where applicable)
• Address vulnerabilities and ensure secure coding practices
  
  

Qualifications

Required Qualifications

• Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent experience
• 5–10+ years of professional experience in C programming
• Strong experience with:
• Linux kernel development
• User space system programming
• Solid understanding of:
• Operating systems concepts (processes, threads, memory, synchronization)
• POSIX APIs, system calls, and low-level I/O
• Experience with:
• Kernel module development and debugging
• Multithreading and concurrency primitives
• IPC mechanisms (pipes, sockets, shared memory)
  
  

• script languages (bash/python);
  

Preferred Qualifications

• Experience with embedded Linux systems
• Knowledge of cross-compilation and toolchains
• Familiarity with networking protocols and kernel networking stack
• Experience with:
• Build systems (Make, CMake, Yocto, Buildroot)
• Version control systems (Git, GitLab/Bitbucket workflows)
• Exposure to security concepts (SELinux, secure boot, sandboxing)
• Hardware interfaces knowledge – PCIE, XFI, ILK, GMII would be appreciated
  

Soft Skills

• Strong analytical and problem-solving skills
• Ability to work independently and in a collaborative team environment
• Clear communication and documentation abilities
• Proactive mindset with ownership of task
  
  

What We Offer

• Opportunity to work on low-level, high-impact system software
• Exposure to cutting-edge kernel and performance optimization challenges
• Collaborative engineering environment
• Competitive compensation and growth opportunities
