Our Networking organization builds systems that manage Internet and backbone traffic, mitigate congestion, and reduce customer impact while enabling network operations to scale efficiently.\nThe Lead Principal Core Infrastructure Engineer mentors engineering teams and leads the architecture of highly scalable, interdependent distributed systems. This role identifies and eliminates performance and scalability bottlenecks for hyperscale workloads, defines scalability requirements with stakeholders, and designs elastic, high-impact systems while driving innovation in data plane platforms.\nWe are seeking a Lead Principal Core Infrastructure Engineer to define technical direction and lead the development of highly available, scalable network control, intelligent routing and automation systems. You will combine deep networking knowledge with software and distributed systems expertise to connect real-time observability with safe, automated routing decisions.\nYour work will span autonomous traffic management, policy-driven network optimization, and software-based routing infrastructure. You will identify performance and scalability bottlenecks, define requirements with stakeholders, and design resilient services that protect customer connectivity during growth, failures, and infrastructure changes.\nThis is a hands-on individual contributor role with broad architectural influence. Based in IDC alongside the engineering team, you will lead initiatives from design through production operations, contribute to critical implementations, and establish standards for availability, security, observability, and safe deployment. You will collaborate across engineering and operations teams while mentoring senior engineers and developing technical leadership.\n Responsibilities\nDefine technical strategy and architecture for scalable routing, network control, and automation systems.\n\nDesign algorithms and distributed services for route computation, congestion management, traffic steering, fault isolation, and recovery.\n\nCorrelate network and infrastructure signals to assess customer impact and enable safe automated responses.\n\nIdentify performance bottlenecks and optimize capacity, resource utilization, routing convergence, and behavior under heavy load.\n\nArchitect and build highly available, fault-tolerant systems with reliable state management, replication, automated failover, and recovery.\n\nDefine service-level objectives, operational KPIs, telemetry, monitoring, and alerting for service health and routing outcomes.\n\nEstablish simulation, scale testing, phased migrations, in-service upgrades, verification, and rollback practices.\n\nLead production troubleshooting, incident response, and root-cause analysis; establish runbooks and drive reliability improvements.\n\nIntegrate security controls, auditability, infrastructure as code, and automated deployment, patching, and lifecycle management.\n\nContribute production-quality code, review designs and implementations, and maintain architecture and operational documentation.\n\nPartner with cross-functional engineering, product, and business stakeholders to define technical strategy and deliver high-impact initiatives.\n\nMentor senior engineers, influence architectural direction, and promote engineering excellence through technical leadership, hiring, and knowledge sharing.\n\nRequired Qualifications\nBachelor’s or master’s degree in computer science, engineering, or a related discipline, or equivalent practical experience.\n\n10+ years of relevant experience building and operating large-scale distributed systems, network control planes, or network automation platforms.\n\nStrong Linux systems and networking knowledge, including containers, process and memory behavior, network namespaces, resource isolation, and packet-level troubleshooting.\n\nExperience designing highly available distributed services with reliable state management, observability, overload protection, and failure recovery.\n\nDemonstrated ability to lead architecture and delivery across teams, resolve ambiguous requirements, communicate technical trade-offs, and mentor senior engineers.\n\nDeep knowledge of L2/L3 networking, routing and switching, software-defined networking, traffic engineering, and WAN technologies.\n\nStrong expertise in BGP and MP-BGP, IPv4/IPv6, route reflection, routing policy, and VPN address families, including practical experience with convergence and reachability troubleshooting.\n\nStrong programming skills in one or more languages such as Go, Python, Java, or C++, with experience in API design, concurrency, automated testing, and production debugging.\n\nPreferred Qualifications\nProduction expertise with Junos and Juniper cRPD or comparable virtualized routing platforms.\n\nExperience with BGP Add-Path, Optimal Route Reflection (ORR), Prefix Independent Convergence (BGP-PIC), route-flap damping, and large-scale routing tables.\n\nKnowledge of MPLS, RSVP-TE, PCEP, bandwidth reservation, latency-aware routing, and shared-risk link groups.\n\nExperience with NETCONF, Junos XML APIs, gRPC, OpenConfig, and model-driven network automation.\n\nExperience tuning containerized networking workloads, including cgroups, socket buffers, veth, and SR-IOV.\n\nExperience with infrastructure as code, automated lifecycle orchestration, and rolling upgrades for stateful services.\n\nUnderstanding of Clos fabrics, overlay/underlay integration, ECMP behavior, and backbone transit.\n\nExperience building distributed active measurement and telemetry systems.\n\nExperience with simulation, failure injection, or formal methods to validate complex distributed-system behavior.\n\nExperience applying traffic prediction, machine learning, or AI techniques to network optimization, anomaly detection, or operational intelligence.","description_format":"text","description_chars":5856,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["CRM
