WHAT YOU DO AT AMD CHANGES EVERYTHING

At AMD, our mission is to build great products that accelerate next-generation computing experiences-from AI and data centers, to PCs, gaming and embedded systems. Grounded in a culture of innovation and collaboration, we believe real progress comes from bold ideas, human ingenuity and a shared passion to create something extraordinary. When you join AMD, you’ll discover the real differentiator is our culture. We push the limits of innovation to solve the world’s most important challenges-striving for execution excellence, while being direct, humble, collaborative, and inclusive of diverse perspectives. Join us as we shape the future of AI and beyond. Together, we advance your career.

• Drive performance optimization end-to-end across the stack on leading models and customer-relevant serving configurations, closing competitive gaps through kernel and systems-level optimizations
• Profile, diagnose, and resolve the hardest cross-stack performance bottlenecks, from GPU kernels and operator dispatch to framework-level scheduling and multi-node communication
• Diagnose kernel-level performance issues using profiling tools: identify occupancy limitations, L2 cache thrashing, register pressure, memory coalescing issues, etc, and translate findings into actionable optimizations
• Lead customer-facing technical engagements: present findings, recommend optimizations, and deliver measurable performance uplifts
• Integrate and optimize custom kernels (Triton, Gluon, CK, PyDSL, ASM, AITER) within serving frameworks, understanding dispatch paths, shape extraction, and backend selection
• Optimize multi-node distributed inference: communication-compute overlap, parallelism strategies, and scale-out performance
• Develop and refine shared performance optimization methodology that raises the bar across the broader team
• Leverage AI agents to accelerate daily work and define best practices for AI-assisted performance engineering
• Upstream optimizations into open-source frameworks such as vLLM, SGLang, and PyTorch

• 7+ years of software development experience in GPU computing, AI systems, or high-performance computing
• Deep hands-on experience with AI serving frameworks (vLLM, SGLang, TensorRT-LLM, or similar) and their internals
• Strong background in end-to-end workload profiling and bottleneck diagnosis: you can trace from user request to GPU kernel and back
• Understanding of GPU kernel performance characteristics: occupancy, register and LDS pressure, memory coalescing, cache utilization, wavefront scheduling, and instruction-level bottlenecks
• Ability to read and reason about kernel-level profiling data and translate it into concrete optimization actions. You may not write kernels from scratch daily, but you can tell exactly why one is slow and what needs to change
• Understanding of model architectures (transformers, MoE, diffusion), inference paradigms (speculative decoding, prefill-decode disaggregation, continuous batching), and how they map to hardware
• Experience with custom kernel development or integration (HIP, CUDA, Triton, CK, or similar)
• Understanding of multi-GPU and multi-node distributed systems: scale-up and scale-out topologies, RCCL/NCCL, RDMA, and communication-compute overlap
• System and rack-level design awareness: understanding performance tradeoffs across the full deployment stack
• Strong proficiency in Python and C++
• Customer-facing technical leadership experience: ability to engage with customers, present findings, and drive decisions
• Fluent in AI-assisted development: daily user of AI agents and tools, with a mindset toward defining new AI-powered workflows
• Strong Linux systems knowledge
• Excellent written and verbal English communication skills
