Online security company McAfee plans to lay off 107 employees at its Hillsboro office, according to a letter it sent to Oregon employment officials.

McAfee said in a written statement Tuesday that it’s investing in growing its operations but “must balance the needs of the business with those of our workforce.”

The company’s statement did not disclose additional details, but a person familiar with McAfee’s operations indicated the Hillsboro site still employs well over 200 and that there were no corresponding cuts planned elsewhere in the company.

The layoff notice to the state indicates the job cuts are concentrated among software engineers. They take effect December 31.

The person indicated the Hillsboro layoffs reflect changes in McAfee’s workforce to provide comprehensive security from individual devices to large data centers.

Previously owned by Intel, McAfee spun out as a separate business three years ago. Intel sold a majority stake in the company to TPG in exchange for $3.1 billion in cash and the chipmaker retained a minority stake.

McAfee moved its Oregon operations from Intel sites into Lattice Semiconductor’s former headquarters in Hillsboro. The company had 375 employees in 91,000 square feet when it moved in last year.

McAfee laid off 200 employees companywide at the start of the year, according to the online technology news site The Information. The publication said at the time that private equity firm TPG, McAfee’s largest shareholder, wanted to boost profits.

Oregon’s jobless rate remains at a historic low of 4.1 percent but there have been a succession of high-profile layoffs this year at employers including NORPAC, Nestlé, Insitu, Union Pacific and Harry’s Fresh Foods.

State employment officials said earlier this month that Oregon’s monthly job growth is nearly at a standstill after years of rapid expansion.
