Software Engineer, Traffic Infrastructure

Místo konáníMenlo Park, CA
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’s Traffic team is seeking experienced software engineers to build terabit class systems for balancing and managing application traffic. Our Traffic team builds global and local load balancers, acceleration proxies, RPC frameworks, content delivery networks, and mobile networking stacks, plus the automation machinery that’s required to operate an internet scale edge network and handle all of Facebook’s DNS and HTTP traffic. We operate a large network of POPs around the world that we use to accelerate site traffic and cache CDN content, and we own all layer 4 and layer 7 traffic management for Facebook. We glue these varied network services together in order to orchestrate the delivery of bits from our servers to your phone or desktop. If you want to work on services like this and make a big impact, then we want to talk to you. If you don’t have relevant experience in this space, but are a solid systems engineer who is enthusiastic about building billion user load balancers and other insane pieces of traffic infrastructure, then we also encourage you to apply. In many ways, motivation and determination trumps relevant experience; we want to work with amazing people no matter what kinds of software they have built before. Apply now and learn more about what we’ve built so far, and what we have planned for the next few years. We’re pretty sure it will knock your socks off. This position is full-time (based in Menlo Park, CA) and there are minimal travel requirements.
