We are seeking a highly skilled Senior Software Developer with strong expertise in C programming to work across Linux kernel space and user space components. The role involves designing, developing, optimizing, and maintaining low-level system software, with a focus on performance, reliability, and security. 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

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-levelI/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-solvingskills
• 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
