Software Engineer, Network Infrastructure

Meta's Network Infrastructure Engineering team builds and operates the software systems that power one of the largest and most complex networks in the world. In this role, you will design and develop the software that manages, automates, and optimizes Meta's global network infrastructure - spanning data centers, backbone networks, and edge services. You will work at the intersection of distributed systems and network engineering, building tools and platforms that ensure reliability, performance, and scalability for billions of users.Design and develop software systems for network infrastructure automation, configuration management, and operational tooling across Meta's global network Build and maintain distributed services that manage network device state, topology, and telemetry at scale Develop and improve network monitoring, alerting, and observability platforms to reduce mean time to detection and mitigation during network incidents Collaborate with network engineers and cross-functional partners to define requirements and translate them into reliable, scalable software solutions Drive architecture decisions for network automation systems, evaluating trade-offs across reliability, performance, and operational complexity Design and implement A/B testing and staged rollout frameworks for network configuration changes to reduce risk during deployments Establish and maintain service level objectives for network infrastructure services, building dashboards and runbooks to support incident response Identify and address performance bottlenecks in network control plane and data pipeline systems through instrumentation and profiling Mentor other engineers on the team by sharing domain expertise, reviewing designs, and contributing to engineering standards and best practices Lead retrospectives on network incidents and drive implementation of follow-up improvements to prevent recurrenceBachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience 6+ years of experience in software engineering with a focus on network infrastructure, distributed systems, or network automation 6+ years of experience programming in C, C++, or Go in a production environment Experience designing and operating large-scale distributed systems or network management platforms Experience with network protocols and concepts such as BGP, OSPF, ECMP, switching, routing, or traffic engineering Experience building observability systems including metrics collection, alerting, and dashboards for large-scale infrastructure Experience with software-defined networking (SDN), network operating systems, or network device APIs such as OpenConfig or gNMI Experience with stream processing or time-series data pipelines for high-volume network telemetry Experience contributing to or operating on-call rotations for critical network infrastructure services Experience developing network automation frameworks for configuration management, topology discovery, or change validation at scaleMeta 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.Meta is proud to be an Equal Employment Opportunity employer.
