Facebook was built to help people connect and share, and over the last decade our tools have played a critical part in changing how people around the world communicate with one another. With over a billion people using the service and more than fifty offices around the globe, a career at Facebook offers countless ways to make an impact in a fast growing organization.Facebook is seeking an Embedded Software Engineer to join our Infrastructure Team. We believe connecting the world is one of the greatest challenges of our generation, and that everyone deserves access to the knowledge, tools and opportunities that come from being connected. Thats why we, along with other tech companies, launched Internet.org, a global partnership to make the Internet available to the two thirds of the worlds population that doesnt have it. 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 innovate services. Join us as we build the technical foundation upon which the world shares and connects. This position is located in our Woodland Hills office (near Los Angeles).
