The position requires strong low-level systems experience and the ability to work across hardware, OS, and platform boundaries.

Responsibilities

• Design, develop, and maintain kernel-level network drivers across supported operating systems (e.g., Linux/KVM, ESX, Windows).
• Support integration of new Ethernet technologies and network interface cards.
• Own network-related bug fixes, performance improvements, and stability enhancements.
• Provide network driver support for major and minor product releases, ensuring quality and release readiness.
• Investigate and resolve customer-critical networking issues and escalations.
• Support customer Proof-of-Concepts (POCs) that require deep networking or driver-level expertise.
• Collaborate with hardware, platform, QA, and customer-facing teams to diagnose and resolve complex, cross-layer issues.
• Participate in code reviews, design reviews, and documentation to support long-term platform maintainability.

• Mentor junior engineers and contribute to technical skill development across the team.

Qualifications

• Strong experience in kernel-level or driver development, with a focus on networking.
• Proficiency in C/C++ and low-level systems programming.
• Experience working with Linux kernel networking stack, device drivers, or equivalent low-level OS components.
• Understanding of Ethernet technologies, NICs, interrupts, DMA, and performance considerations.
• Experience debugging complex system-level issues across hardware and software boundaries.
• Proficiency with version control and bug tracking systems (e.g., Git, JIRA).
• Experience working in Agile development environments, using tools such as Jira.
• Hands-on experience with debugging and performance analysis tools (e.g., perf, Wireshark, kernel debuggers).
• Experience participating in code review and design review processes.

Preferred Qualifications

• Experience with multi-OS driver support (Linux/KVM, Windows, ESX).
• Familiarity with virtualization platforms and hypervisors.
• Experience supporting customer escalations or field issues involving low-level system components.
• Prior work in high-availability, fault tolerant, or mission-critical systems.
• Familiarity with modern development workflows and tools, including AI-assisted development tools (e.g., Cursor).
