Ndimensions Labs - Boston, MA or Toronto, Canada
Full-time, long-term contract
$100,000 - $300,000 per year (commensurate with experience)

Ndimensions Labs is a group of technologists from MIT, the University of Waterloo, and the University of Washington, focused on building the infrastructure and learning systems behind next-generation robotics AI. Our focus is not only on deploying models, but on training, adapting, and scaling them for real-world embodied intelligence.

We are developing agents that learn from large-scale multimodal data and improve through iterative fine-tuning, evaluation, and feedback. This role centers on the model training stack: foundation model adaptation, large-scale training pipelines, alignment, and continual learning for robotics.

We are hiring an AI/ML Engineer focused on model training and fine-tuning for robotics AI systems. You will work at the intersection of ML training, multimodal learning, and robotics data systems. The emphasis is on model quality, adaptation, robustness, and generalization.

This position is dedicated to:

• Training multimodal models from scratch or from pretrained checkpoints.
• Fine-tuning foundation models (vision, language, and vision-language-action) for embodied tasks.
• Designing scalable training and evaluation pipelines.
• Improving data quality and alignment methods.

• Train and adapt multimodal/foundation models (ViTs, VLMs/VLAs, diffusion policies, world models) for embodied robotics.
• Build scalable training and fine-tuning pipelines (distributed multi-GPU/multi-node; parameter-efficient fine-tuning such as LoRA/adapters, distillation, QAT).
• Own data and iteration loops: curation, filtering, augmentation, and tight feedback with data and systems teams.
• Improve policies via learning methods (imitation, offline RL, RL) and rigorous evaluation/ablations (robustness, generalization, failure modes).

• Strong background in machine learning and deep learning.
• Hands-on experience training or fine-tuning large transformer-based models.
• Experience with distributed training (e.g., PyTorch DDP, FSDP, Deep Speed).
• Understanding of multimodal learning (vision-language, vision-action, or similar).
• Experience working with large datasets and building reproducible ML pipelines.
• Strong Python skills and familiarity with ML tooling ecosystems.

• Experience training or fine-tuning models for robotics, embodied AI, or control.
• Background in reinforcement learning, imitation learning, or policy optimization.
• Publications in top ML or robotics venues.
• Location:
  
  Boston, MA or Toronto, Canada.
• Salary range: $100,000 - $300,000 per year, based on qualifications and experience.
• Equal Opportunity Statement:
  Ndimensions Labs is an equal opportunity employer and welcomes applicants from all backgrounds.
