Software Development Engineer - GPU Interconnects and Ethernet AI
Originally posted 2 November 2026 by the employer.
About the role
AMD is seeking a Software Development Engineer to drive the design, development, and bring-up of networking software for GPU scale-up interconnects and Ethernet-based AI fabrics. The role focuses on driver, firmware, and systems software layers for AMD Helios rack-scale deployments across scale-up interconnects and scale-out networking.
What you'll do
- Lead the design and development of networking software for GPU scale-up interconnects and Ethernet-based AI fabrics on AMD Helios rack-scale systems.
- Develop and optimize Linux kernel drivers, embedded firmware, and user-space software for GPU interconnect, NIC, and switch subsystems.
- Drive hardware and software bring-up of new ASICs and platforms, including SerDes, link initialization, Ethernet MAC/PCS/FEC configuration, topology discovery, and validation.
- Collaborate with switch software teams on switch configuration, forwarding, QoS, telemetry, and fabric management for scale-up and scale-out topologies.
- Define firmware, driver, and management interfaces along with control-plane protocols between GPUs, switches, and fabric management software.
- Analyze end-to-end network performance, latency, bandwidth utilization, congestion behavior, and communication efficiency across multi-node and rack-scale deployments.
What you'll need
- Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent.
- Experience in networking, systems software, driver, or firmware development.
- Strong C/C++ programming skills with attention to code quality.
- Linux kernel driver development experience, including PCIe devices, DMA, interrupts, and memory management.
- Embedded firmware development experience on microcontrollers or SoC management processors within RTOS or bare-metal environments.
- Knowledge of Ethernet (MAC, PCS, FEC, SerDes, link training, and auto-negotiation) and high-speed link bring-up.
Nice to have
- Experience with GPU interconnect or scale-up fabric technologies such as UALink, Infinity Fabric/xGMI, NVLink, or Ethernet-based scale-up.
- Experience with datacenter switch software such as SONiC, SAI, or switch ASIC SDKs.
- Experience with network protocols and transports including RDMA, RoCE, InfiniBand, or TCP/IP.
- Familiarity with Python or Go for tooling.
- Hands-on experience with ASIC, GPU, NIC, or switch bring-up.
- Knowledge of reliability, availability, and serviceability (RAS) considerations in rack-scale or datacenter deployments.
