About the job
Designs, trains, and interprets foundation models that learn from raw, multimodal sensor data to understand and reason about the physical world.
What you'll do
- Develop sensor-data foundation models and methods for representation learning, multimodal alignment, and self-supervised learning.
- Adapt pretrained models to new datasets, sensing modalities, environments, and use cases; diagnose failures and run experiments to improve performance.
- Work with engineering and product teams to bring research into production, and publish and share research findings.
What they ask for
- 8+ years of experience developing advanced ML/AI systems, focused on real-world sensor data.
- Expertise in deep learning architectures, especially transformers, representation learning, and large-scale model training.
- Strong research and experimentation skills, including designing and evaluating new approaches.
- Excellent programming skills in Python and deep learning frameworks such as PyTorch.
Nice to have
- Familiarity with LLMs.
- Experience with self-supervised or contrastive learning on large unlabeled datasets, or with large-scale or distributed training.
Tools
Python, PyTorch, transformers, LLMs, NeurIPS, ICML, ICLR
