⌛ Permanent Role

Key responsibilities

• Profile end-to-end distributed training runs to identify bottlenecks across compute, GPU memory, and inter-GPU communication.
• Influence architectural decisions to improve efficiency and reliability of large-scale training jobs, including developing Triton/CUDA kernels when needed.
• Design and implement model scaling, parallelisation, and memory optimisation techniques for training workloads with very large context sizes.
• Collaborate closely with ML Researchers to diagnose architectural inefficiencies, ensure new research ideas scale efficiently in practice, and share internal knowledge on optimisation.
• Drive productionisation and serving of models from the research side, including improving inference efficiency via techniques such as quantisation.

Must have

• Strong understanding of modern ML architectures and large-scale training pipelines.
• Hands-on experience running distributed training jobs on multi-GPU systems.
• Advanced profiling and debugging across CPU, GPU, memory usage, latency, and inter-GPU communication.
• Strong programming skills in Python.
• Experience with model scaling and parallelisation strategies, including tensor and pipeline parallelism.

Nice to have

• Familiarity with NCCL, MPI, and distributed communication primitives.
• Knowledge of PyTorch and Triton internals.
• Programming experience with C++ and CUDA.

Benefits

• Competitive compensation with salary and equity and comprehensive benefits
• Relocation support for employees moving to join the team in the office location.
• A mission-driven, low-ego culture valuing diversity of thought, ownership, and bias towards action.
