We power some of the world's largest residential and business broadband deployments, serving millions of subscribers with strict availability and scale requirements. We value technical depth, automation-first engineering, continuous learning, collaborative problem-solving, and responsible adoption of AI-assisted development practices.\nYour Impact\nAs a Software Engineer on the cnBNG Control Plane, you will own the design, delivery, and end-to-end quality of carrier-grade subscriber-management features in a cloud-native architecture. You will build session-handling, CP-UP separation, redundancy, and scale capabilities that keep millions of subscribers online across Silicon One-based UPFs - and own their unit, integration, system, and scale validation with automation-first practices. You will mentor junior engineers and use modern AI-assisted tools to accelerate development, testing, and debugging. The successful candidate will independently own a significant Control Plane feature area and its unit/integration/system/scale validation and automation, deliver production-quality code and tests, lead sophisticated investigations across CP and Silicon One UPFs, and provide evidence-based release recommendations - while influencing design, mentoring, and using AI-assisted tools responsibly with security and engineering accountability.\nDesign, develop, and maintain cnBNG Control Plane microservices (C/C++/Go) on the SMI/Kubernetes platform, interworking with IOS-XR / Silicon One-based User Plane Functions.\nImplement and enhance subscriber-management functionality: PPPoE/IPoE session bring-up, DHCPv4/DHCPv6 (server/proxy/relay), Prefix Delegation, RADIUS/AAA, PAP/CHAP, accounting, Change of Authorization, IPAM, subscriber policy, and QoS.\nDevelop and harden CP-UP separation over the State Control Interface - session programming, state download/replay, and reconciliation between the Control Plane and Silicon One UPFs.\nBuild features for scale and high availability: cluster upscale, N:M and geo/warm redundancy (SRG), CP-GR switchover, and subscriber-session continuity during CP-UP communication failures.\nOwn quality end-to-end: write unit tests and component/integration tests; design and execute system, regression, scale, performance, resiliency, and high-availability tests for your features.\nDevelop reusable, scalable test automation (Python; pyATS/Genie or equivalent) and integrate it into CI/CD pipelines and regression suites.\nBuild and maintain containerized/virtual/cloud-based test environments (Docker, Kubernetes, SMI) and validate subscriber-scale, traffic, failover, upgrade/rollback, process-restart, and subscriber-churn scenarios.\nOptimize control-plane performance, memory, and convergence for millions of subscribers across large UPF fleets.\nDevelop and maintain gRPC/REST APIs and YANG/OpenConfig models, plus CLI and model-driven telemetry for configuration and operational visibility.\nTroubleshoot sophisticated, distributed issues across CP, Silicon One UPFs, and the SMI/Kubernetes stack; drive RCA using logs, traces, core dumps, RADIUS transactions, and telemetry.\nManage code with Git; participate in code reviews; collaborate with Test Engineering on feature, scale, and HA validation.\nWork with architects, DE/DT leads, and PLM to deliver features across the release lifecycle (BC/CC, AC/EC, DEVELOPING, FCS).\nActively use approved AI coding assistants and engineering agents for code generation, unit/automation test creation, static analysis, log analysis, defect triage, and documentation - validating AI-generated output responsibly.\nMinimum Qualifications (Must-Have)\nBachelor's or master's degree in Computer Science, Electrical/Computer Engineering, Telecommunications, or a related field.\nExperience in systems/embedded or cloud-native software engineering for networking products.\nStrong programming in C/C++ and/or Go on Linux; Python for test automation and scripting.\nExperience writing unit, integration, system, and scale/performance tests, and building automation (pyATS/Genie or equivalent) integrated into CI/CD and regression pipelines.\nSolid understanding of IP networking and subscriber/broadband protocols: PPPoE, IPoE, DHCPv4/v6, RADIUS/AAA, PPP, L2TP.\nKnowledge of Cisco Silicon One (SiOne) NPU-based User Plane Functions (UPFs) - data-plane/forwarding architecture, CP-to-UPF programming, and how subscriber sessions map to NPU forwarding.\nCloud-native fundamentals: Docker, Kubernetes, microservices, and service meshes.\nExperience building and consuming gRPC/REST APIs and data models (YANG, protobuf).\nDistributed-systems concepts: high availability, redundancy, state reconciliation, and scale.\nStrong Linux skills; experience with Git, code reviews, debugging, and CI/CD pipelines.\nAI-assisted engineering is a must: use of AI coding assistants (e.g., GitHub Copilot) and a working understanding of generative AI, AI agents, MCP (Model Context Protocol), reusable AI skills, prompt/context management, and responsible validation of AI-generated output.\nPreferred Qualifications\nExperience with BNG/CUPS, CP-UP separation, SRG geo/warm redundancy, or 5G/BNG converged-core architectures.\nExperience with SMI (Subscriber Microservices Infrastructure) or similar cloud-native telco platforms.\nFamiliarity with Silicon One platform families (Cisco 8000 / ASR 9000 / NCS) as User Planes.\nScale/performance characterization and traffic/subscriber-simulation tools (IXIA/Spirent).\nDatabases/caching for network state (SQL/NoSQL, key-value stores, etcd); AAA/policy, IPAM at scale, and QoS.\nTelemetry, NETCONF/RESTCONF/gNMI, OpenConfig; Aha/Jira API suites.\nWhy Cisco?\nAt Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era - and beyond.
