we are redefining the economics of AI infrastructure. Our mission is to democratise AI by significantly reducing the Total Cost of Ownership (TCO) of hardware systems — a critical barrier to scalable adoption.

Our proprietary MIMO-over-copper technology powers a high-performance, chiplet-based AI memory fabric that is both scalable and energy-efficient. Unlike traditional interconnects, our solution reduces power consumption significantly while preserving high bandwidth and ultra-low latency — unlocking unprecedented efficiency for AI training and inference at scale.

our architecture is not just an incremental improvement — it’s a foundational shift in how AI hardware is built for the future.

The responsibility of this role is to develop and integrate the Linux CXL/PCIe kernel modules and services for Kandou’s Memory fabrics products for Data center servers

• Strong academic and technical background in Electronics & Computer engineering. At a minimum, a Bachelor’s in EE or Computer Science is required, and a Master’s is preferred.
• Experience developing Linux kernel drivers for Storage/SSD/NVMe PCIe/CXL drivers, CXL driver’s integration with memory management and NUMA architecture
• Minimum 10-12 years’ experience developing firmware for Server, Memory controllers and DDR PHY programming

Required experience

• Hands-on experience designing and developing device drivers and kernel programming for PCIe/PCIe root complex/CXL with proficiency in C (preferred) and system programming
• Familiar with Bare-metal and RTOS/Zephyr OS firmware development and enablement
• Familiar with SoC interfaces to common IP blocks such as PCIe Controllers, NVME Controllers, DDR controllers, AMBA/AHB interfaces, on-chip memory interfaces, and other similar interfaces
• Work with various cross-functional groups such as architect, other development teams, QA/validation, product management and customer teams across various sites

Preferred experience

• Experience with storage or SSD drivers , including NVMe, PCIe, CXL or memory management concepts, health monitoring and device management frameworks
• Hands-on experience with simulation or virtual platform–based development (e.g., Renode, QEMU, or similar)
• Experience working with Linux OS community
