LinkedIn, the professional social networking platform owned by Microsoft, said on Monday that it would cut about 668 jobs, or roughly 3 percent of its work force.

The cuts, which affect LinkedIn’s engineering, product, talent and finance teams, is the company’s second round of layoffs this year. In May, LinkedIn laid off 716 employees worldwide and said it was reducing its business in China, citing declining demand in an uncertain job market.

LinkedIn, which has 19,500 employees across 36 offices globally, did not detail the reasons for the job cuts on Monday. In a statement, the company said it was “streamlining our decision making” and that it would continue “to invest in strategic priorities.”

A LinkedIn spokeswoman declined to comment beyond the statement. In May, Ryan Roslansky, LinkedIn’s chief executive, said the company was seeing “shifts in customer behavior and slower revenue growth.”
