CentralSquare Technologies will close its San Diego offices and expects to lay off up to 144 workers, according to a filing with the state’s Employment Development Department.

The Florida-based business is comprised of three different companies that merged in September: San Diego-based TriTech Software Systems, Florida-based Superion, and the public sector portion of Georgia-based Aptean’s business. TriTech, founded by Chris Maloney in 1993, provides software to support EMS, fire and police agencies, including computer-aided dispatch systems that help route first responders to an emergency.

According to the state filing, the former TriTech office in San Diego will be permanently closed, resulting in the layoffs. The company still maintains offices in North Carolina, Iowa, South Dakota and Massachusetts, and TriTech had 600 employees as of 2015.

A CentralSquare spokesperson said the company would offer local employees the opportunity to relocate or work remotely.

The combined company under CentralSquare is much larger with more than 2,100 employees. It has $400 million in revenue, according to Government Technology magazine. Bain Capital, which acquired TriTech earlier this year, and Vista Equity Partners, which acquired Florida-based Superion earlier this year, are co-owners of CentralSquare.
