Chris Corrado, formerly chief information officer for AT&T Wireless, will replace the company's current CTO, Marty Abbott. Corrado's experience also includes positions at Wipro and Merrill Lynch. He will report to eBay Chief Operating Officer Maynard Webb.
Corrado and Abbott will initially work together for several months. Corrado will then take over responsibility for eBay's site operations, IT and security.
Abbott will leave the company after having been there for more than five years.
"Marty came to eBay shortly after the site outages in 1999 and has led every major system improvement since that time," Webb said in a statement. "Today eBay's platform architecture is a core strength of our company. We are enormously grateful for Marty's efforts and wish him the very best for the future."
eBay has around 125 million users. The company's third-quarter 2004 sales reached $806 million, a 52 percent increase compared with the same period a year earlier.
