C Systems Engineer at KadMap

About the job

• The ideal candidate will work on the core infrastructure that powers our operating system-level platform. This role focuses on Linux internals, kernel configuration, protocol stack optimization, and low-level systems programming.
• You will help design, implement, and fine-tune essential components of our system, such as memory management, networking, and runtime environments to deliver a fast, stable, and secure foundation for our broader platform. Ideal candidates are comfortable writing C, navigating system calls, debugging kernel-space issues, and building tools that run close to hardware.

Responsibilities 

OS & Kernel Engineering

• Modify and configure kernel subsystems (e.g., networking, memory, process scheduling).
• Write or maintain simple kernel modules, system daemons, or startup routines.
• Build minimal Linux variants or adapt existing OS components for custom use cases.

Network & Protocol Work

• Tune and optimize networking stack configurations (TCP/IP, DNS, routing).
• Develop or adapt simple communication protocols for internal or local systems.
• Assist in debugging and profiling network performance issues.

Systems Tooling & Automation

• Build or extend CLI tools for tracing, logging, and system performance analysis.
• Automate kernel builds, image packaging, and deployment for development and testing environments.

Platform Support & Debugging

• Investigate low-level bugs or stability issues within the system.
• Collaborate with other engineers to validate changes and test across hardware variations.
• Provide technical input during design reviews involving systems-layer decisions.

Core Requirements

• Proficiency in C with some experience writing system-level code.
• Solid understanding of Linux internals (system calls, boot process, user-space interfaces).
• Familiarity with kernel modules, init systems (e.g., systemd), and basic OS architecture.
• Experience using tools like strace, perf, tcpdump, or gdb.
• Comfort working with bash or Python for scripting and automation.

Nice to Have (Not Required)

• Experience with QEMU, KVM, or other virtualization tools.
• Exposure to embedded Linux environments or custom distributions.
• Familiarity with networking concepts like NAT, routing tables, or tunneling protocols.
• Contributions to any low-level systems projects (even personal or hobbyist).
• Manage and monitor installed systems
• Test and maintain operation systems
• Monitor application performance

Qualifications 

• Bachelor's degree in Computer Science or related field
