About the role

  • This is a broad role that can be tailored to your specific area of expertise: data pipelines, training infrastructure or inference.

Responsibilities

  • Maintain an effective research codebase with good ergonomics, optimizing for fast iteration and correctness
  • Own infrastructure for model training: job scheduling, checkpointing, metrics, and logging
  • Profile and optimize gpu utilization, memory usage and training throughput
  • Build low-latency inference pipeline for real-time robot control, apply quantization, distillation and model compilation to optimize inference performance
  • Design high-throughput pipelines for ingesting, validating, and transforming multimodal robot data (video, proprioception, actions)
  • Build storage systems and metadata indexing for efficient dataset management at large scale
  • Optimize dataloaders, sharding and prefetching to minimize time from data arrival to model training
  • Build research tooling for debugging, visualization and experiment analysis

Requirements

  • Hands-on experience with ML training infrastructure, ideally PyTorch
  • Comfort reasoning about performance, memory, I/O, and GPU utilization
  • Experience managing training workloads (SLURM, Kubernetes, or similar)

Nice to have

  • Experience with robotics data pipelines or multimodal models
  • Deep ML systems experience: training compilers, custom kernels, runtime optimization
  • Hands-on GPU performance tuning
  • Experience with serialization formats for high-performance systems (Protobuf, FlatBuffers, MCAP)
  • Even if you don't meet every single requirement, we encourage you to apply.
  • Studies show that women and underrepresented groups often hold back unless they meet 100% of the criteria - we don't want that to be the reason we miss out on great talent.
