San Antonio-based insurance and banking giant USAA announced Tuesday that it is adding as man as 3,500 new jobs to keep up with expected membership growth.

The company announced expansions for San Antonio and Phoenix and positions will include member contact representatives in investments, insurance, banking and claims; underwriters; information security specialists; business and financial analysts; and modeling and statistical analysts.

According to the company, the San Antonio expansion could bring as many as 1,000 new jobs by the end of 2015 to its headquarters community where it already employs more than 16,400 people.

To supplement its main campus, which USAA estimates is at nearly 90 percent capacity, the company announced it will occupy additional leased space in the San Antonio area. That new facility will hold as many as 1,000 employees.

In Phoenix, USAA plans to break ground next month on construction of a 380,000-square-foot expansion of its existing campus in northern Phoenix.
