Blackbaud said Thursday that it would cut a "small number" of jobs as part of a restructuring effort, but the Charleston technology stalwart didn't say how many workers it was letting go.

In a statement, the company's top human resources executive said the layoffs were limited to its customer support and professional services groups. 

"We merged and streamlined functions within these groups resulting in some redundancies and regrettably it affected a small number of jobs in those teams," said John Mistretta, executive vice president of human resources. "It’s important to us to continue to deliver a best-in-class customer experience and re-invest back in innovation, and that means we must consistently evaluate how we operate to ensure that we are as effective and efficient as possible."

The Charleston-based company, which sells software and services to the nonprofit sector, is the largest employer in local tech sector, and it had nearly 3,100 employees worldwide at the end of 2015. About half of them work in the Lowcountry.

Blackbaud says it's still hiring in other parts of its business, and the company has promised ambitious growth. When it announced a new headquarters on Daniel Island last year, it said it would add 300 jobs locally by 2021.

The state Commerce Department said Blackbaud would be able to claim tax credits for the 300 jobs. The company says it still expects to hit those targets.

"We are continuing to hire - and continuing to grow," Mistretta said. "We’re confident we’ll reach the goal of 300 jobs over the next 5 years."
