AI Performance Engineers focus on pushing machine learning workloads to peak hardware efficiency, with emphasis on low‑level optimization and kernel performance.

• Analyze and explore recent ML models and workloads, understand their compute, memory, and instruction‑level behavior, and optimize them on AMD GPUs for both inference and training
• Design, implement, and tune GPU kernels at a low level, including C++, intrinsics, and hand‑written GPU assembly
• Perform deep profiling and bottleneck analysis across compute, memory, and execution pipelines
• Optimize instruction scheduling, memory access patterns, and occupancy to achieve the final 5% of performance uplift
• Work closely with hardware, compiler, and software teams to drive performance improvements across the full stack
• The position is part of an AI and GPU performance optimization workstream at AMD
• Collaborate with AI developers, compiler engineers, and hardware architects to understand performance limits and opportunities
• Work with multiple teams located locally in Finland and the UK, as well as internationally
• Communicate performance bottlenecks, solutions, and optimization strategies clearly across teams
• Benchmark, analyze, and optimize performance of key machine learning workloads on single‑ and multi‑GPU AMD systems
• Design, implement, and tune high‑performance GPU kernels for tensor operations such as matrix multiplication, attention, and convolutions
• Apply instruction‑level and memory‑level optimizations to achieve measurable performance improvements
• Deliver high‑quality, well‑documented, production‑ready performance‑critical code
• Low‑level performance optimization
• GPU programming and hardware architecture
• Instruction scheduling, memory hierarchies, and execution pipelines
• Extracting the maximum achievable performance from hardware under real‑world constraints
• Passionate about getting the best out of the hardware and motivated by the challenge of delivering that extra 5% performance uplift

• Strong understanding of GPU architectures and low‑level optimization techniques, including memory hierarchy, instruction scheduling, and performance tradeoffs
• GPU software development using HIP, CUDA, or OpenCL
• Strong C++ skills for performance‑critical systems programming
• Experience with profiling, debugging, benchmarking, and performance analysis tools
• Experience in HPC or performance‑critical systems
• Familiarity with modern ML frameworks (e.g., PyTorch, MIOpen)
• Familiarity with tile programming and related frameworks (Triton, Cutlass, etc.)
• Strong written and spoken English
• Experience with Docker, Singularity, Slurm, or Kubernetes is a plus
• BSc, MSc, PhD, or equivalent experience in Computer Science, Engineering, Physics, or a related technical field

• Experience with GPU assembly programming and/or compiler backends
• Experience with CPU assembly (x86 or Arm) and microarchitectural optimization
• Background in compilers, code generation, or instruction‑level optimization
