Description

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.  

THE ROLE:

As an AI Performance Engineers you will focus on pushing machine learning workloads to peak hardware efficiency. The emphasis of this call is on analysis, profiling, debugging and optimization at application/workload-level; however a broad understanding of low-level GPU execution and kernel optimization is a major advantage.

KEY RESPONSIBILITIES:

• Explore and benchmark ML models and workloads (including diffusion models, LLMs, and multimodal systems) to identify bottlenecks across compute, memory, and networking layers.
• Optimize performance for inference and training on AMD GPUs, including parallelization strategies, quantization techniques, serving orchestration, network communication and distributed execution.
• Perform deep profiling to uncover inefficiencies in ML frameworks, data pipelines, compiler tools, and key tensor operations such GEMMs, Convs and Attention, to name a few.
• Support AMD top-tier customers to improve model throughput, reduce latency, and optimize resource utilization across multi-GPU and cluster environments.
• Work closely with hardware, compiler, and software teams to drive improvements across the full ROCm stack
• Communicate performance bottlenecks, solutions, and optimization strategies to stakeholders.
• Work with international teams located across Europe, US and Asia.

EXAMPLE TASKS FOR THE FIRST 6 MONTHS:

• Benchmark and profile the latest e.g. DeepSeek model on single- and multi-GPU AMD systems.
• Identify top bottlenecks (e.g. gemms, moe, attn, vae) and drive improvements to reach peak performance.
• Evaluate competing hardware (other GPUs, TPUs, NPUs...) to understand where we lead and where we fall behind.
• Contribute improvements to popular inference and training frameworks such vLLM, SGLang, xDiT, Primus.
• Produce ambitious performance uplift plans, and execute them with your team.

IDEAL CANDIDATE PROFILE: 

• Running the latest Frontier AI workloads (LLMs, diffusion, multimodal) at scale.
• Profiling, debugging and optimizing complex ML workloads on PyTorch and JAX.
• High-performance networking for AI infrastructure (RDMA, InfiniBand, RoCE, UCX).
• Strong understanding of GPU architectures and performance trade-offs on AI workloads.
• Disaggregated LLM serving systems (KVCache management, prefill-decode separation, GPU-direct).
• Pre-training, fine-tuning, instruct-tuning, LoRa and other training-related experiences.
• You are proactive, a self-starter, and passionate about delivering performance improvements at scale.

REQUIRED SKILLS & QUALIFICATIONS: 

• Experience with profiling, debugging, benchmarking, and optimization tools.
• Familiarity with ML frameworks (e.g., PyTorch, JAX, TF) and inference serving frameworks (e.g., vLLM, SGLang).
• Strong C++ and/or Python skills, along the basics: unix, git, terminal, debugging, testing, thinking...
• Experience with Docker, container orchestration (Kubernetes), and job schedulers (Slurm).
• Ability to work independently and collaboratively in a multi-cultural team.
• Excellent communication skills in a fast-moving environment.

NICE TO HAVE:  

• Experience with AMD tooling (not mandatory if strong fundamentals).
• GPU kernel development experience with HIP, CUDA, or OpenCL
• Tile-programming experience (Triton, Pallas, Gluon, Cutlass, cuDSL...)
• Experience in multi-GPU cluster environments (single- and multi-node).
• Background in high-performance networking for AI infrastructure.
• Familiarity with compiler backends or code generation.
• Experience with KVCache optimization and memory hierarchy tuning.

 ACADEMIC CREDENTIALS:

• BSc, MSc, PhD or equivalent experience in Computer Science, Electrical Engineering or a related field
