ATM-maker Triton Systems has laid off workers at its Long Beach headquarters and manufacturing plant, but the company won’t reveal how many.

Human resources director Brian Goff said Tuesday’s action was the first restructuring in about eight years. Without giving exact numbers, he said the cuts affected less than one-third of the staff.

Goff said the cutbacks were necessary so the manufacturer could focus on its core business in North America, where its largest markets are.

“Rather than chase business in other markets, we’re going to focus on North America, the market that built this company,” he said.

Before Tuesday’s layoffs, Triton had about 500 employees, some of them in Canada, Europe and Memphis.

The jobs cut were made throughout the organization, Goff said, but were “more heavily on the professional side.”

He said no more layoffs were planned.

Goff said there were a few cuts to the small staff at the Memphis service office.

The layoffs, which were effective immediately, will not reduce production at the company’s 88,000-square-foot plant in the Long Beach Industrial Park, Goff said.

“We don’t see any cutback in the level of production as far as units produced,” he said.

Triton is the second largest ATM maker in North America and the fourth largest in the world. There are 145,000 Triton units operating in 23 countries, according to the company.

Triton was started in 1979 and was bought by publicly traded Dover Corp. in March 2000.
