About the role

This role offers the rare opportunity to train production LLMs from scratch using our unique, continuously-growing dataset of construction footage and operational data.

Develop pre-training strategies using construction documentation, safety protocols, building codes, and industry knowledge to create models that understand construction contexts deeply
Design and implement distributed training systems capable of handling billion+ parameter models across
Build scalable data ingestion, cleaning, and preprocessing systems for training on diverse construction data sources
Develop systems that seamlessly integrate human labeling with
We're seeking an exceptional Staff / Principal Research Scientist to build our foundation model capabilities from the ground up.
You'll work directly with our team to design, train, and deploy large-scale language and multimodal models tailored to construction domain expertise.
We help teams reduce labor costs, improve safety, and deliver projects faster.
To date, we've captured 50,000+ hours of construction footage across 7 states and have recently partnered with the nation's #2 hard-hat manufacturer, Studson, to develop custom hardware purpose-built for the field.
Now, we're building the team to scale nationwide.

About Ironsite Construction is one of the most complex and labor-intensive industries, spending $7 trillion annually on labor, but productivity losses cost $1.6 trillion per year due to outdated management tools.

We put cameras on construction workers' hard hats and vests, then use advanced computer vision to analyze what's actually happening on job sites.
Build and train vision-language models that can reason about construction footage, technical drawings, and textual data simultaneously
Deploy and monitor computer vision models in challenging real-world environments with strict latency and reliability requirements
Design model architectures, training objectives, and optimization strategies to train large language models and multimodal models (combining vision + language) specifically for construction use cases
Ironsite leverages wearable cameras combined with human labeling and AI vision language models to drive on-site productivity, safety & training for crafts workers.
