Research Engineer - Vision & Vision-Language Models (AI)

Location: On-site in San Francisco, United States

Company

hirify.global's Vision Team develops AI models for image understanding, computer use, and agentic visual tasks.

What you will do

• Develop vision-language models across pretraining, post-training, reinforcement learning, and evaluation.
• Run large-scale vision and multimodal training experiments.
• Source, generate, curate, process, and evaluate vision and multimodal datasets, including synthetic data.
• Develop computer-use agents, visual agents, and other multi-turn agentic vision systems.
• Design architecture, data, and training-methodology ablations and improvements.
• Optimize model-training and data-processing stacks for large-scale execution.

Requirements

• Strong machine learning intuition, research judgment, and the ability to take ambiguous problems from conception through experimentation and execution.
• Strong implementation and prototyping skills, with the ability to turn ideas into experiments quickly.
• Experience with large-scale model pretraining, post-training, reinforcement learning, or related methodologies.
• Experience with vision, vision-language, video, multimodal models or datasets, and image-processing pipelines.
• Experience training models on large-scale, multi-node GPU clusters and working with highly parallel data-processing pipelines.
• Proficiency with PyTorch and Python, strong experimental methodology, and the ability to work effectively in large pre-existing codebases.

Nice to have

• Experience with computer-use agents, visual agents, GUI understanding, or multi-turn multimodal tasks.
