The Bank of New York Mellon Corp. announced this morning it plans to add 135 positions in its treasury services group in Pittsburgh.

The New York-based financial services giant, formed when local corporate icon Mellon Financial Corp. was acquired by The Bank of New York last year, has announced 755 new positions since January 2007 after pledging to create 1,000 to 2,000 new jobs in the Pittsburgh area over three to five years.

It has not said how many jobs have been eliminated, but in April the company said the net increase in local jobs since January 2007 has been 482. In May, it decided not to expand a data center in Armstrong County, upsetting state Sen. Don White, but promised the 200 new technology-oriented jobs associated with the expansion would still be added in Downtown Pittsburgh.

The Bank of New York Mellon said today it currently employs 6,550 in the Pittsburgh area, up from less than 6,100 at the start of 2007.
