You will be joining the team that is responsible for the end-to-end health (performance and reliability) of Meta's backbone networks. You will build tools and use automation to efficiently scale how we mitigate real-time impact to the network, identify and investigate long-term trends into performance and risks in our backbone, and drive innovative solutions to monitor and improve Meta's current and future backbone network products.Our backbones continue to rapidly expand globally, driven most recently through the network demands that our AGI journey brings. We support both our "Classic Backbone", that transports traffic destined to people using Meta's products, and our "Express Backbone", that handles machine to machine traffic between our Data Centers.Engineers that typically thrive in this role are hybrid software and network engineers who are curious about how systems work, how they fail, and how we can increase their reliability. You have the opportunity to dig into interesting challenges in the networking and software domains, at a scale that offers new challenges on a daily basis.

Network Production Engineer - Backbone Responsibilities:

• Write and review code, develop documentation and capacity plans, and debug the hardest problems, live, on some of the largest and most complex networks and systems in the world
• Participate in a weekly on-call rotation and be an escalation contact for service incidents
• Perform deep dives on complex technical issues across networks, ranging from automated tooling to hardware failures and network issues
• Manage and maintain multi-vendor, multi-protocol backbone and edge networks
• Analyze data to diagnose and identify root causes to network issues
• Define, develop, and optimize automated network monitoring systems to mitigate and remediate network events
• Proactively identify gaps across our systems and own the resolution

Minimum Qualifications:

• Currently has, or is in the process of obtaining a Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience. Degree must be completed prior to joining Meta.

• Knowledge in routing and switching - hardware design and knowledge of forwarding and data planes

Preferred Qualifications:

• BS or MS in Computer Science, Computer Engineering, or Network Engineering
• Expert knowledge of TCP/IP and IPv6
• Experience operating and designing SDN-based backbone networks
• Experience working in a multi-vendor network environment
• Experience with developing distributed systems and operating them at scale
• Experience with automation frameworks and tools such as Ansible, Puppet, or Chef

About Meta:
Meta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today—beyond the constraints of screens, the limits of distance, and even the rules of physics.
