Description

About


Teaching a robot a new task usually takes hundreds or thousands of demonstrations, plus a round of task-specific training. This team is building the opposite: a foundation model that picks up a new manipulation task from far fewer examples, even when the objects have moved.


It’s an early-stage, stealth robotics startup with a small founding team. The model is transformer-based and trained largely in simulation, on large GPU clusters in the cloud.


This is an early hire to own distributed training end-to-end — scaling from tens of GPUs to potentially thousands, with the freedom to challenge the existing stack and shape long-term infrastructure decisions. A hands-on IC seat, not a management one.


What you’ll do



  • Own distributed training infrastructure and scale it across large GPU clusters

  • Push training from tens of GPUs to hundreds, and eventually potentially thousands

  • Improve GPU utilisation, throughput and end-to-end training efficiency

  • Optimise networking, storage, checkpointing and data pipelines for large jobs

  • Profile and optimise across the full training stack

  • Make long-term infrastructure and tooling decisions

  • Potentially support cloud inference and deployment as the product develops


What you’ll need



  • Hands-on experience training large transformer models across multi-node GPU clusters

  • Deep distributed-training experience (PyTorch, NCCL, DeepSpeed, Megatron-LM/FSDP)

  • Cloud-based GPU workloads, ideally AWS

  • A track record improving utilisation, networking, storage, checkpointing and reliability

  • Strong enough to lead this area independently and level up the existing team

  • A hands-on IC who still wants to write code

  • Happy to work on-site five days a week in London (visa sponsorship and relocation available)


Bonus



  • Large-scale VLA or robotics model training

  • Large-scale computer vision transformer training

  • Foundation model or LLM training infrastructure

  • Ability to contribute to model architecture or transformer design
