Modular Installer Jobs in California (NOW HIRING)

COMPANY DESCRIPTION
Impact Housing (IH) is a vertically integrated modular design-builder and developer headquartered in Southern California.
Our mission is to continuously evolve the world's most sophisticated and efficient housing delivery system. We pursue this mission by reimagining every element of how multifamily projects are designed, manufactured, and built-driving down costs, shortening schedules, and expanding access to high-quality housing for the people who need it most, whether through LIHTC or unsubsidized projects.
To date this decade, the IH team has built or is actively developing close to 1,500 modular units demonstrating a scalable, repeatable path to affordability. With the capability to produce approximately 1,000 units per year today, IH is expanding to meet growing demand in San Diego, Los Angeles, and beyond.
We are now entering the next stage of our growth and strengthening every team across the company to achieve our next set of goals. We plan to manufacture and build more than 10,000 units through 2030. To accomplish this, we are implementing the Lean Standard Model company-wide; deploying AI at every level of the company; and positioning IH as a national thought leader in modular development.
The foundation for our success is firmly in place. Join us as we scale our operations, transition into a higher-capacity manufacturing facility powered by smart automation and robotics, expand our production capacity by more than 3x in the Western U.S., and prepare for future national growth.
