About the Job

Requirements

  • In-depth knowledge of PCIe, Ethernet, and other high-speed I/O interfaces used in datacenter and accelerator products.
  • Strong understanding of PCIe ordering models, producer-consumer ordering, ARM ordering behavior, DMA flows, and high-speed serial interface behavior.
  • Strong understanding of PCIe Gen6/Gen7 requirements, including FLIT mode, PAM4 signaling implications, link training, latency, error handling, and system-level tradeoffs.
  • Experience with PCIe error containment and recovery mechanisms such as Advanced Error Reporting (AER), Downstream Port Containment (DPC), Configuration Request Retry Status (CRS), Function Level Reset (FLR), and reset separation.
  • Experience with I/O virtualization and isolation technologies such as SR-IOV, SIOV, PF/VF isolation, and related software-visible requirements.
  • Strong understanding of RAS, telemetry, reliability, and security requirements for server-class SoCs and accelerator subsystems.
  • Good knowledge of scale-up and scale-out architectures, including PCIe switch fabrics, NIC connectivity, host-to-accelerator orchestration, and rack-level deployment considerations.
  • Bachelor's degree in Electrical Engineering, Computer Science, Computer Engineering, or a related field and 10+ years of Software Engineering, Electrical Engineering, Systems Engineering, or related work experience; or a master's degree in one of those fields and 8+ years of related work experience; or a PhD in one of those fields and 6+ years of related work experience.
  • At least 3 years of experience with high-performance designs involving PCIe, Ethernet, or other high-speed I/O interfaces.

Responsibilities

  • Define and deliver high-performance I/O architectures for next-generation AI products in the datacenter.
  • Define subsystem architecture and drive requirements from the accelerator-card and server level through full-rack scale-up and scale-out deployments.
  • Work effectively in a high-caliber, international, multi-site engineering team.

Desired Qualifications

  • Good understanding of PCIe integrity, security, and confidential-compute features such as IDE, DOE/SPDM, TDISP, SR-IOV, and SIOV.
  • Strong familiarity with PCIe CEM standards, add-in card deployment constraints, retimers, signal-integrity considerations, and system-level validation flows.
  • Good understanding of emerging AI interconnect standards and ecosystems such as UCIe, UALink/UAL, and UEC.
  • Good understanding of PCIe firmware, BIOS/UEFI, operating-system, driver, and system-software requirements.
  • Good understanding of high-speed SerDes and PHY technologies, including PCIe PHY, Ethernet PHY, PAM4 signaling, and power/performance tradeoffs.
  • Good knowledge of server SoC architectures with emphasis on security, RAS, virtualization, IOMMU/SMMU, DMA, address translation, and telemetry.
  • Ability to engage with customers, product management, systems teams, and cross-functional architecture stakeholders to gather requirements and drive technical alignment.
  • Excellent written and verbal communication skills, with the ability to create architecture specifications, requirement documents, and executive-level technical summaries.

About the Company

Qualcomm

Designs mobile chips and licenses wireless patents

Qualcomm designs the Snapdragon processors and modems inside many Android phones, and it licenses its wireless patents to device makers around the world. It helped commercialize CDMA, the cellular technology behind 3G networks, and its patents cover core parts of the 4G and 5G standards that phones use to connect. The company does not run its own chip factories; contract foundries make its chips, which it sells to makers of phones, PCs, cars, and connected devices. Device makers also pay Qualcomm royalties for using its patented technology, which forms a second business alongside chip sales. Qualcomm was founded in 1985 and is based in San Diego, California.
