Just ahead of its blowout first-quarter earnings report on April 25, Google laid off at least 200 employees from its "Core" teams, in a reorganization that will include moving some roles to India and Mexico, CNBC has learned. The Core unit is responsible for building the technical foundation behind the company's flagship products and for protecting users' online safety, according to Google's website. Core teams include key technical units from information technology, its Python developer team, technical infrastructure, security foundation, app platforms, core developers, and various engineering roles. Many Core teams will hire corresponding roles in Mexico and India, according to internal documents viewed by CNBC. Asim Husain, vice president of Google Developer Ecosystem, announced news of the layoffs to his team in an email last week.
