Senior Full Stack Engineer (NYC, Austin or Remote US)

At Trunk Tools, we’re the leading AI company revolutionizing construction—the second-largest industry on earth. With deep traction among Fortune 500 general contractors, we have raised $30M from top investors including Redpoint and Innovation Endeavors.

Our mission is to build the future of construction through intelligent automation. Construction is a $13+ trillion industry still operating primarily in analog—and we’re changing that by embedding AI directly into the jobsite.

Founded by builders and technologists (Stanford, MIT), our experienced team has delivered software used by 140,000+ field professionals, impacting millions of users and contributing to $10B+ in built projects. We're deeply rooted in construction, with many of our team coming from the field.

After years of developing the “brain” of construction, we are now deploying AI agents and workflows to automate critical tasks—beginning with intelligent document processing, Q&A capabilities and rapidly expanding across operational processes. We currently have 50+ employees, including 20 engineers, and have doubled our size in the last 12 months. We’re continuing to grow rapidly as we launch and scale multiple AI agents this year.
