AI Framework and Performance Experts - VLLM

ADVANCE YOUR CAREER. ADVANCE THE WORLD. 

At AMD, we believe technology has the power to solve the world’s most important challenges. From advancing healthcare and scientific discovery to powering AI and the technologies people rely on every day, innovation at AMD is shaping the future. 

Whether you’re designing next-gen processors, enabling AI breakthroughs, or bringing leading edge products to market, every role at AMD contributes to something bigger — technology that moves the world forward. Join us and, together, we’ll 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

PREFERRED EXPERIENCE:

Inference Stack Knowledge

• Hands-on understanding of vLLM, SGLang, or similar inference stacks

• Experience with distributed inference scaling and a proven track record of contributing to upstream open-source projects

Deep Learning Integration

• Strong experience integrating optimized GPU performance into machine-learning frameworks (e.g., PyTorch, TensorFlow) for high-throughput and scalable inference

Kernel & Inference Frameworks

• Strong background in NVIDIA, AMD, or similar GPU architectures and kernel development

Software Engineering

• Expertise in Python and preferably experience in C/C++, including debugging, performance tuning, and test design for large-scale systems

High-Performance Computing

• Experience running large-scale workloads on heterogeneous GPU clusters, optimizing for efficiency and scalability

Compiler & Runtime Optimization

• Understanding of compiler and runtime systems, including LLVM, ROCm, and GPU code generation

ACADEMIC CREDENTIALS:

• Master’s or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
