Embedded Software Engineer, Connectivity Lab

(Menlo Park, 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 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. That’s why we, along with other tech companies, launched Internet.org, a global partnership to make the Internet available to the two thirds of the world’s population that doesn’t have it. The Connectivity Lab team has been working on developing new platforms for connectivity on the ground, in the air and in orbit. We are looking for someone to develop embedded SW for future novel communication systems for wireless and optical technologies. The successful candidate will research and implement full cycle of embedded development SW for future connectivity solutions.
