The company's devices and services organization, which oversees the development of products such as Alexa, Echo smart speakers and Kindle e-readers, was among the groups affected.
Still, Amazon remains "fully committed" to the Alexa unit despite the company taking steps to be more disciplined with costs in "a very uncertain economy," Limp said.
At one point, Amazon had 5,000 people working on Alexa and Echo.
Amazon has sold devices such as the Echo at or near cost because its goal isn't to make money from them.
The prices of some commodities used in Amazon devices, such as memory and displays, has increased, and those could get passed along to consumers, he said.
