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 ROLE:

As a senior member of the LLM inference framework team, you will be responsible for building and optimizing production-grade single-node and distributed inference runtimes for large language models on AMD GPUs. You will work at the framework and runtime layer, driving performance, scalability, and reliability, enabling tensor parallelism, pipeline parallelism, expert parallelism (MoE), and single-node or multi-node inference at scale. Your work will directly power customer-facing deployments and benchmarking platforms (e.g., InferenceMax, MLPerf, strategic partners, and cloud providers) and will be upstreamed into open-source inference frameworks such as vLLM and SGLang to make AMD a first-class platform for LLM serving. 

This role sits at the intersection of inference engines, distributed systems, and GPU runtime and kernel backends. 

THE PERSON:

You are a systems-minded ML engineer who thinks in terms of throughput, latency, memory movement, and scheduling, not just model code. 

You are comfortable reading and modifying large-scale inference frameworks, debugging performance across GPUs and nodes, and collaborating with kernel, compiler, and networking teams to close end-to-end performance gaps. 

You enjoy working in open source and driving architecture-level improvements in inference platforms. 

KEY RESPONSIBILITIES:

Inference Framework & Runtime 

• Architect and optimize distributed LLM inference runtimes based on in-house LLM engines or open-source stacks such as vLLM, SGLang, and llm-d 

• Design and improve TP / PP / EP (MoE) hybrid execution, including KV-cache management, attention dispatch, and token scheduling 

• Implement and optimize multi-node inference pipelines using RCCL, RDMA, and collective-based execution 

Performance & Scalability 

• Drive throughput, latency, and memory efficiency across single-GPU and multi-GPU clusters 

• Optimize continuous batching, speculative decoding, KV-cache paging, prefix caching, and multi-turn serving 

GPU & Backend Integration 

• Work with AMD GPU libraries (AITER, HIPBLAS-LT, RCCL, ROCm runtime) to ensure inference frameworks efficiently use FP8 / FP4 GEMM and FlashAttention / MLA 

• Collaborate with compiler teams (Triton, LLVM, ROCm) to unblock framework-level performance 

Open Source & Customer Enablement 

• Upstream features and performance fixes into vLLM, SGLang, and llm-d 

• Enable customer PoCs and production deployments on AMD platforms 

• Build and maintain benchmark-grade inference pipelines
