About the role

Senior technical leadership role driving end-to-end delivery of scale-up networking and GPU software stack for AMD Instinct GPUs, spanning architecture, firmware, drivers and ROCm stack for rack-scale AI systems.

Responsibilities

  • Scale-up networking: define and drive software architecture for scale-up switch fabrics connecting AMD Instinct GPUs within a rack-scale system, including Ethernet-based fabrics and emerging standards such as UALink and Ultra Ethernet.
  • Lead switch software integration (e.g., SONiC, SAI, switch SDKs), including link bring-up, SerDes/retimer tuning, FEC/BER characterization, topology discovery, routing, congestion management and telemetry.
  • GPU firmware: architect and develop GPU firmware components (system management, power/thermal, security, RAS, fabric/link management), and drive firmware packaging, update flows (PLDM/Redfish) and BMC integration.
  • Drivers: lead development and optimization of Linux kernel drivers for Instinct GPUs (amdgpu/KFD), including memory management, GPU-to-GPU communication over the scale-up fabric, partitioning, virtualization, error handling and recovery.
  • Software stack: drive enablement and performance of the ROCm stack on scale-up systems, including runtime, communication libraries (RCCL), and integration with PyTorch, JAX and inference serving engines (e.g., vLLM, SGLang).
  • Own new-platform bring-up from pre-silicon (emulation/simulation) through first silicon, system integration, and production qualification.
  • Lead cross-layer debug and root-cause analysis of complex issues spanning silicon, firmware, driver, fabric and application layers.
  • Define performance, reliability and scalability goals for collective communication and multi-GPU workloads, and drive optimizations to meet them.
  • Collaborate with silicon architects, hardware, switch, cloud/OEM partners and customers to influence product roadmaps and strategic technical decisions.
  • Mentor engineers, set technical direction and engineering best practices, and coordinate execution across globally distributed teams.

Qualifications

  • Extensive experience in system software development for GPUs, accelerators, NICs or network switches.
  • Strong background in data center networking: Ethernet (L1–L3), high-speed SerDes, FEC, RDMA/RoCE, congestion control, and switch ASIC programming (e.g., Broadcom SDK, SAI, SONiC).
  • Familiarity with scale-up interconnects and fabrics such as UALink, Ultra Ethernet, AMD Infinity Fabric™, NVLink or similar.
  • Hands-on experience with firmware development for SoCs or accelerators, including embedded C/C++, boot flows, power management, security, and BMC/out-of-band management (Redfish, PLDM, MCTP).
  • Strong Linux kernel and device driver development experience (PCIe, DMA, IOMMU, memory management, interrupt handling).
  • Knowledge of GPU architecture and GPU software stacks (ROCm/HIP, CUDA, or similar), and of collective communication libraries (RCCL/NCCL, MPI).
  • Familiarity with deep learning frameworks (e.g., PyTorch, JAX, TensorFlow) and distributed training/inference at scale.
  • Proven track record of leading new hardware platform bring-up and debugging complex hardware/software interactions using tools such as JTAG, protocol analyzers and logic analyzers.
  • Proficiency in C/C++ and Python; experience with Go or Rust a plus.
  • Experience setting technical direction and influencing across multiple teams and organizations.
  • Excellent communication, collaboration and leadership skills.
  • Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related discipline; PhD a plus.
