Wireless Communications Systems Intern

(Menlo Park, CA – Woodland Hills, CA)

Facebook’s mission is to give people the power to share, and make the world more open and connected. Through our growing family of apps and services, we’re building a different kind of company that helps billions of people around the world connect and share what matters most to them. Whether we’re creating new products or helping a small business expand its reach, people at Facebook are builders at heart. Our global teams are constantly iterating, solving problems, and working together to make the world more open and accessible. Connecting the world takes every one of us—and we’re just getting started.

Facebook is seeking interns who will help develop theory, algorithms, and simulations relating to advanced digital wireless communication concepts. The Connectivity Lab team has been working on developing new platforms for connectivity on the ground, in the air and in orbit. For all of these systems, the team is looking at free-space optical communication, a way of using light to transmit data through space using invisible, infrared laser beams. To make this a reality, we need to scale our infrastructure and ensure that it operates efficiently so that we can deliver innovative services.This is a full-time, 12 week internship position and we have opportunities in Menlo Park and Woodland Hills, CA.
