Job Description:WHAT YOU DO AT AMD CHANGES EVERYTHINGAt 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.THE ROLEAs a Senior Member of Technical Staff, you will be a technical leader in Large Language Model (LLM) inference and kernel optimization for AMD GPUs. You will play a critical role in advancing high-performance LLM serving by optimizing GPU kernels, inference runtimes, and distributed execution strategies across single-node and multi-node systems.This role is deeply focused on LLM inference stacks, including vLLM, SGLang, and internal inference platforms. You will work at the intersection of model architecture, GPU kernels, compiler technology, and distributed systems, collaborating closely with internal GPU library teams and upstream open-source communities to deliver production-grade performance improvements.Your work will directly impact throughput, latency, scalability, and cost efficiency for state-of-the-art LLMs running on AMD GPUs.THE PERSON:You are a senior systems engineer with deep LLM domain knowledge who enjoys working close to the metal while keeping a strong understanding of end-to-end inference systems. You are comfortable reasoning about attention, KV cache, batching, parallelism strategies, and how they map to GPU kernels and hardware characteristics.You thrive in ambiguous problem spaces, can independently define technical direction, and consistently deliver measurable performance gains. You balance strong execution with thoughtful upstream collaboration and maintain a high bar for software quality.KEY RESPONSIBILITIES
  • Optimize LLM Inference Frameworks
Drive performance improvements in LLM inference frameworks such as vLLM, SGLang, and PyTorch for AMD GPUs, contributing both internally and upstream. * LLM-Aware Kernel DevelopmentDesign and optimize GPU kernels critical to LLM inference, including attention, GEMMs, KV cache operations, MoE components, and memory-bound kernels. * Distributed LLM Inference at ScaleDesign, implement, and tune multi-GPU and multi-node inference strategies, including TP / PP / EP hybrids, continuous batching, KV cache management, and disaggregated serving. * Model–System Co-DesignCollaborate with model and framework teams to align LLM architectures with hardware-aware optimizations, improving real-world inference efficiency. * Compiler & Runtime OptimizationLeverage compiler technologies (LLVM, ROCm, Triton, graph compilers) to improve kernel fusion, memory access patterns, and end-to-end inference pipelines. * End-to-End Inference Pipeline OptimizationOptimize the full inference stack—from model execution graphs and runtimes to scheduling, batching, and deployment. * Open-Source LeadershipEngage with open-source maintainers to upstream optimizations, influence roadmap direction, and ensure long-term sustainability of contributions. * Engineering ExcellenceApply best practices in software engineering, including performance benchmarking, testing, debugging, and maintainability at scale.PREFERRED EXPERIENCE
  • Good LLM Knowledge
Deep understanding of Large Language Model inference, including attention mechanisms, KV cache behavior, batching strategies, and latency/throughput trade-offs. * LLM Inference FrameworksHands-on experience with vLLM, SGLang, or similar inference systems (e.g., FasterTransformer), with demonstrated performance tuning. * GPU Kernel DevelopmentProven experience optimizing GPU kernels for deep learning workloads, particularly inference-critical paths. * Distributed Inference SystemsExperience designing and tuning large-scale inference systems across multiple GPUs and nodes. * Open-Source ContributionsTrack record of meaningful upstream contributions to ML, LLM, or systems-level open-source projects. * Programming & Debugging SkillsStrong proficiency in Python and C++, with deep experience in performance analysis, profiling, and debugging complex systems. * High-Performance ComputingExperience running and optimizing large-scale workloads on heterogeneous GPU clusters. * Compiler & Systems BackgroundSolid foundation in compiler concepts and tooling (LLVM, ROCm, Triton), applied to ML kernel and runtime optimization.ACADEMIC CREDENTIALS:
  • Master’s or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field
