Senior Systems Software Engineer - Base OS Kernel for AI Platforms

About the Role

We are seeking a Senior Systems Software Engineer - Base OS Kernel to join our team remotely. This role focuses on designing, developing, and optimizing the Base OS kernel for cutting-edge AI and high-performance computing (HPC) platforms. As a Senior Systems Software Engineer, you will work closely with enterprise customers, hardware teams, and firmware engineers to tackle complex kernel challenges and ensure scalable, high-performance operating systems.

What You'll Do

• Architect, optimize, and enable the Base OS kernel for AI and HPC platforms, ensuring scalability and reliability across enterprise deployments.
• Collaborate with Tier-1 customers to integrate and optimize internal Linux distributions on advanced hardware.
• Solve complex kernel-level problems related to high core counts, large memory footprints, and multi-rack interconnects.
• Lead hardware bring-up from pre-silicon simulation through OS boot and production stability.
• Develop automated test suites to validate kernel stability, performance, and quality throughout the development lifecycle.
• Anticipate long-term architectural challenges and implement maintainable solutions for future system expansion.
• Mentor and collaborate with engineering teams, providing guidance on kernel architecture, system performance, and best practices.

Requirements

• BS/MS in Computer Science, Electrical Engineering, or equivalent experience; 8+ years in Linux kernel or low-level systems development.
• Expert-level C programming with a strong understanding of concurrency, synchronization, and locking in large-scale NUMA systems.
• Deep knowledge of OS concepts including memory management, interrupt handling, process scheduling, and virtualization (KVM/QEMU, SR-IOV).
• Proven experience with PCIe Gen5/6, CXL, and ARM64 (v8/v9) architectures preferred.
• Demonstrated ability to debug, optimize, and maintain kernels in high-density or large-cluster environments.
• Strong collaboration, mentorship, and communication skills with the ability to balance immediate goals with long-term architectural vision.
• Experience with CI/CD pipelines, automated validation frameworks, or open-source kernel contributions is a plus.

Nice to Have

• Experience with advanced Linux kernel subsystems.
• Familiarity with system-level optimizations for AI workloads.
• Knowledge of emerging technologies in HPC.

What We Offer

• Competitive base salary with potential equity and performance-based bonuses.
• Remote work flexibility across the United States.
• Comprehensive healthcare coverage including medical, dental, and vision.
• Retirement savings plans and life insurance.
• Paid time off, professional development, and learning opportunities.
• Exposure to state-of-the-art AI, HPC, and system-level software projects in a high-impact environment.
• Collaborative culture emphasizing mentorship, technical excellence, and long-term innovation.
