The moves add to a trio of Barclays U.S. investment bankers that UBS announced it hired last month.
Many Credit Suisse bankers are based in the United States.
These bankers follow Barclays ex-colleagues Marco Valla, Jeff Hinton and Kurt Anthony, whose moves to UBS were announced in April.
Sources told Reuters last month that UBS plans to retain only a small number of Credit Suisse senior bankers with strong client relationships.
At Barclays, Braham was global chair of investment banking for technology, while Hardegree served as vice chair and head of technology M&A.
