You will build the intelligence layer behind tools that interpret construction blueprints and support faster, more efficient project estimation, with a focus on turning computer vision and AI research into useful prototypes., * Develop and improve computer vision, machine learning, and AI systems, focusing on the intelligence layer rather than the application layer.

• Evaluate and apply current computer vision models, large language models, and other AI approaches to challenging construction data problems.
• Build and ship initial prototypes quickly, then refine them using feedback from users.
• Contribute pragmatically to early-stage product work beyond core modeling when needed.

• Hands-on applied computer vision and machine learning experience, including Python and deep learning; candidates across experience levels are considered, from 0 to 10+ years.
