About the job
Build and improve vision and vision-language models for image understanding, computer use, and agentic visual tasks across the full model development lifecycle.
What you'll do
- Develop and evaluate vision-language models through pretraining, post-training, reinforcement learning, and large-scale training runs.
- Source, generate, curate, process, and evaluate vision and multimodal datasets.
- Improve model architectures, training methods, and training and data-processing performance for visual-agent tasks.
What they ask for
- Strong machine-learning intuition and ability to take ambiguous problems from conception through experimentation and execution.
- Strong implementation and prototyping ability, with capacity to learn unfamiliar technical areas quickly.
- Proficiency with PyTorch and Python.
- Ability to collaborate and communicate effectively across research and engineering.
Nice to have
- Experience with multimodal models or datasets, large-scale training, reinforcement learning, vision datasets, or image-processing pipelines.
- Experience with computer-use or visual agents, frontend or mobile development, large-scale GPU clusters, or published machine-learning research.
