Linux Kernel Developer

🌍 Remote (EU-based candidates only)
📌 Full-time, Long-term
💼 Experience: 6+ years

About the Project

Our client is a leading provider of accounting SaaS solutions. The project centers on the development of a custom hypervisor aimed at reducing total cost of ownership for memory-intensive applications and improving system performance. The current focus is porting the technology from Intel to ARM platforms.

As a Linux Kernel Developer, you'll join a specialized Virtualization Team responsible for building low-level tools and components from scratch—not just configuring or integrating existing solutions.

Main Responsibilities

• Design and develop tools for virtualization, including original development and enhancement of existing tools.
• Contribute to kernel and driver development with a focus on both ARM and x86 architectures.
• Collaborate with the team to implement low-level modules for virtualization and multi-core management.
• Port and optimize the software stack from Intel to ARM platforms.
• Create and maintain technical documentation.
• Support performance optimization and troubleshoot low-level issues.

Required Skills

✅ Must-Have:

• Proficient in ANSI C programming.
• Hands-on experience with Linux kernel or driver development (ARM & x86).
• Strong knowledge of multi-core programming, including interrupts, memory barriers, and lockless data structures.
• Low-level x86 or ARM programming, including processor opcodes/emulation.
• Solid background in Linux POSIX development (beyond system integration).
• Experience writing technical documentation and low-level module design.
• Excellent command of English (written & spoken).
• Effective communication and collaboration skills.

➕ Nice to Have:

• Experience optimizing software for ARM processors.
• Familiarity with Hypervisors and virtualization tools (e.g., KVM, QEMU).
• Knowledge of Assembly (x86_64 or aarch64).
• Experience with VMWare, Azure, or AWS is a strong advantage.

Team Insights

We're looking for hands-on kernel engineers with real development experience—whether it’s contributing to the Linux kernel, creating custom distributions, writing device drivers, or building memory/file system/network stack tools. Candidates with virtualization experience (especially with KVM, QEMU, or large-scale cloud platforms) will stand out.
