About Assembly OSM

Our team has developed billions of dollars of urban real estate including the tallest high-rise modular tower in North America (461 Dean Street), and has led major manufacturing operations at companies like Tesla and General Motors.

The Assembly approach is quite different than the modular solutions that have been deployed in the past. The process is more similar to aerospace manufacturing than construction -- leveraging high fidelity digital twin models and distributed manufacturing to make our business more scalable and resilient.

If our mission speaks to you, we encourage you to apply!
