Software Engineer — Smart Construction 3D - Hybrid in Philadelphia, PA

EARTHBRAIN•Philadelphia, PA

7d•Hybrid

About The Position

Build software that changes how the physical world gets built. At EARTHBRAIN, we're building technology that transforms construction jobsites into intelligent, connected environments. Born from Komatsu—one of the world's largest construction equipment manufacturers—and backed by Komatsu, NTT, Sony, and Nomura Research Institute, EARTHBRAIN combines the speed and ownership of a technology company with the resources and global reach of established industry leaders. Our Smart Construction platform is already deployed across more than 15,000 jobsites in Japan and used in more than 27 countries. Now we're expanding our North American engineering team—and we're looking for experienced software engineers who want to work on technical problems that go far beyond the typical web application. You'll help build 3D products that allow contractors to combine CAD files, aerial and satellite imagery, drone-captured point clouds, terrain data, and other project information to visualize, analyze, and plan complex construction projects. Think centimeter-level terrain precision, massive geospatial datasets, earthwork calculations, digital twins, and interactive 3D environments. And that's only where we're starting. Our longer-term roadmap includes remote and autonomous construction, with cloud systems coordinating fleets of heavy machinery across jobsites.

Requirements
