Software Development Engineer

As 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., * 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 Development Design and optimize GPU kernels critical to LLM inference, including attention, GEMMs, KV cache operations, MoE components, and memory-bound kernels.

• Distributed LLM Inference at Scale Design, 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-Design Collaborate with model and framework teams to align LLM architectures with hardware-aware optimizations, improving real-world inference efficiency.

• Compiler & Runtime Optimization Leverage 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 Optimization Optimize the full inference stack-from model execution graphs and runtimes to scheduling, batching, and deployment.

• Open-Source Leadership Engage with open-source maintainers to upstream optimizations, influence roadmap direction, and ensure long-term sustainability of contributions.

• Engineering Excellence Apply best practices in software engineering, including performance benchmarking, testing, debugging, and maintainability at scale., AMD may use Artificial Intelligence to help screen, assess or select applicants for this position. AMD's "Responsible AI Policy" is available here.

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., * 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 Frameworks Hands-on experience with vLLM, SGLang, or similar inference systems (e.g., FasterTransformer), with demonstrated performance tuning.

• GPU Kernel Development Proven experience optimizing GPU kernels for deep learning workloads, particularly inference-critical paths.

• Distributed Inference Systems Experience designing and tuning large-scale inference systems across multiple GPUs and nodes.

• Open-Source Contributions Track record of meaningful upstream contributions to ML, LLM, or systems-level open-source projects.

• Programming & Debugging Skills Strong proficiency in Python and C++, with deep experience in performance analysis, profiling, and debugging complex systems.

• High-Performance Computing Experience running and optimizing large-scale workloads on heterogeneous GPU clusters.

• Compiler & Systems Background Solid foundation in compiler concepts and tooling (LLVM, ROCm, Triton), applied to ML kernel and runtime optimization., * Master's or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field
