ML Infrastructure Engineer
Hybrid (Amsterdam, Netherlands; Remote - Europe; Remote - United States)Posted 5mo ago
About the role
We are seeking a highly skilled ML/AI Engineer to lead and support benchmarking of GPU platforms for machine learning and AI workloads, evaluating GPU-based hardware performance to inform platform optimization and next-generation hardware development.
Responsibilities
- Work closely with hardware and development teams to profile and analyse GPU performance at the system and kernel level.
- Evaluate and compare GPU performance across different platforms, architectures, and software stacks (e.g., CUDA, ROCm).
- Debug and optimise ML workloads to run efficiently on GPU hardware, identifying and resolving performance bottlenecks.
- Perform acceptance testing for new GPU clusters, ensuring hardware and software meet performance, stability, and compatibility requirements for AI workloads.
- Perform experiments across diverse GPU system configurations to assess the impact of varying interconnect strategies and system-level optimisations on performance and scalability.
- Develop tools and dashboards to visualise performance metrics, bottlenecks, and trends.
- Contribute to internal tooling, frameworks, and best practices
Qualifications
- A profound understanding of theoretical foundations of machine learning
- Deep understanding of performance aspects of large neural networks training and inference (data/tensor/context/expert parallelism, offloading, custom kernels, hardware features, attention optimisations, dynamic batching etc.)
- Deep experience with modern deep learning frameworks (PyTorch, JAX, Megatron-LM, Tensor-LLM)
- Good understanding of the GPU stack: CUDA, NCCL, drivers, and relevant libraries
- Familiarity with containerized environments (e.g., Docker, Kubernetes)
- Strong communication and ability to work independently
