ARM Server Platform I/O & Interconnect Software Architect (PCIe, CXL & Interrupt Architecture)

Job Summary:  

Qualcomm is seeking an experienced ARM Server Platform I/O & Interconnect Software Architect to lead the architecture and software enablement of PCIe, CXL, and Interrupt Controller subsystems for next-generation ARM server SoCs. 

The ideal candidate possesses deep expertise in ARM server architecture, PCIe and CXL technologies, interrupt controller architecture (ARM GIC), virtualization, firmware, and Linux kernel internals. The candidate should be comfortable operating across the entire software stack including platform firmware, operating systems, virtualization, RAS, manageability, and performance optimization. 

As a Software Architect, you will provide technical leadership across SoC architecture, platform firmware, HLOS, virtualization, validation, and customer enablement teams. You will be responsible for defining scalable software architectures that enable high performance, reliability, serviceability, virtualization, and ecosystem compliance for hyperscale datacenter deployments. 

Key Responsibilities: 

• Own the software architecture for PCIe, CXL, and Interrupt Controller subsystems across ARM server platforms, including architecture definition, requirements, enablement strategy, and ecosystem alignment. 

• Drive architecture and software enablement across firmware and HLOS components including: 

• • UEFI/EDK2 

  • Arm Trusted Firmware (TF-A) 

  • OpenBMC 

  • Linux Kernel 

  • KVM/Hypervisors 

• Datacenter operating systems and distributions 

• Collaborate closely with SoC architects, CPU architects, hardware design teams, firmware teams, Linux kernel engineers, validation teams, and product management to deliver production-quality solutions. 

• Define platform software requirements necessary to achieve compliance with industry standards and specifications including: 

• • ARM SBSA 

  • SBBR 

  • SystemReady 

  • PCI-SIG specifications 

  • CXL Consortium specifications 

  • ACPI 

  • UEFI

• Lead architecture reviews and drive software requirements into silicon, firmware, and platform design teams to ensure software-first design decisions. 

• Partner with performance, RAS, and validation teams to define system-level debug, telemetry, error handling, fault isolation, and recovery strategies. 

• Drive upstream-first software development and collaborate with the open-source ecosystem to ensure long-term maintainability and broad OS support. 

• Work directly with hyperscale cloud customers, OEMs, ODMs, and ecosystem partners to understand requirements, review architectural solutions, and support platform commercialization. 

• Prepare and present architecture proposals, design specifications, technical roadmaps, and executive-level reviews for internal and external stakeholders. ​ 

Preferred Qualifications: 

• ​Master’s degree in Computer Science/Engineering, Electrical Engineering, or a related field. 

• Deep expertise in multiple areas including:  

• • PCIe Gen5/Gen6/Gen7 

  • CXL 2.x/3.x 

  • ARM GICv3/v4 

  • SMMUv3 

  • ARM virtualization architecture 

  • Server RAS technologies 

• In-depth knowledge of ARM architectures for various compute environments and relevant ARM (BSA, BBR, BBSR) and NIST specifications. 

• Understanding of confidential computing technologies and trusted firmware architectures.  

• Prior experience delivering platform software for hyperscalers, cloud service providers, OEMs, or datacenter infrastructure products.  

• Demonstrated leadership in open-source software communities and upstream Linux development. ​
