DPU IO Architect, Infrastructure Silicon

Meta's Infrastructure Silicon organization designs custom silicon that powers our data center infrastructure — SmartNICs/IPUs/DPUs, AI accelerators, and networking ASICs. We are looking for a Data Processing Unit (DPU) I/O Architect to own the I/O subsystem and the hardware/software interface between our silicon and the software that drives it - PCIe, DMA and offload engines, I/O virtualization, Confidential Computing, and system management. You'll define how the hardware presents itself to firmware and software - the register and programming models, descriptor and doorbell interfaces, and offload interfaces - and decide what belongs in hardware versus firmware versus software. You'll work hand in hand with the firmware, driver, and RTL teams, and carry your designs from early path-finding through implementation and silicon bring-up.
