Goldman Sachs partner Greg Tusar, who is leaving his job overseeing the bank's electronic trading business, plans to join Getco later this year after the Chicago trading firm completes its acquisition of Knight Capital, according to people familiar with the matter.

Tusar's hire reflects the first big management move by Getco and its chief executive, Daniel Coleman, since Getco and Knight agreed in December to merge. At the combined Getco-Knight, Tusar will oversee the business serving clients.
