- Work at the systems level with CUDA and C++ to remove performance bottlenecks.
- Bring state-of-the-art models into production alongside research and product teams.
- Prototype quickly and iterate against tight product timelines.
- Choose the optimisation approaches and techniques that deliver the most impact.
What We’re Looking For
- 5+ years of engineering or research experience in machine learning, computer vision or graphics.
- Experience with CUDA, C++ and systems-level performance optimisation.
- Strong knowledge of PyTorch or TensorFlow, and clean, maintainable research code.
- Experience optimising state-of-the-art models at real scale. Multimodal models are preferred, ideally video.
- Strong communication, collaboration and documentation skills, with a track record of sustained impact in previous roles.
- Nice to have: experience at a large-scale AI lab or frontier research organisation, and interest in human-in-the-loop creative tools.
What’s On Offer
- $260,000 to $325,000 for US-based candidates. Ranges outside the US will be confirmed separately.
- Remote across North America and Europe.
- Ownership of performance for frontier video models at a smaller, faster-moving company.

- Design and maintain distributed training infrastructure, including tensor and context parallelism, FSDP and fault-tolerant multi-node setups.
- Profile and accelerate real-time multimodal inference using CUDA graphs, KV cache optimisation, operator fusion and latency reduction.
- Improve the efficiency and reliability of training infrastructure at scale.
- Contribute across the stack, from low-level kernels to high-level model design.
What We’re Looking For
- 5+ years in ML systems, GPU optimisation or performance engineering. High-trajectory candidates with less experience are also considered.
- Hands-on kernel development in CUDA or Triton.
- Training at scale on thousands of GPUs, or demonstrable efficiency gains from constrained compute in a startup setting.
- Deep knowledge of PyTorch or JAX internals and low-precision techniques (FP8, INT8), plus distributed systems experience with NCCL and model parallelism.
- A hands-on individual contributor with a track record of sustained impact in previous roles.
- Nice to have: torch.compile, inference optimisation with Flash Attention or TensorRT, generative or diffusion model infrastructure, open-source contributions and kernel competitions.
What’s On Offer
- Up to $370,000 plus ISO equity.
- Fully remote, anywhere within six hours of New York time.
- Visa sponsorship available.
- End-to-end ownership of performance across the stack, without big-tech bureaucracy.
