Senior Software Engineer, Control Plane (Go) - Hypershield

Cisco develops networking and security technologies that connect and protect organizations across digital infrastructure. This role designs and develops control plane software for smart switching platforms and distributed firewall systems, focusing on APIs, policy orchestration, and secure service integration. The engineer will collaborate with control plane, data plane, and platform teams to deliver scalable networking security capabilities.

Responsibilities:

• Design and develop control plane features for network security products using Go in Linux-based environments
• Build and maintain APIs and cloud-based configuration services that translate network and security policy into configurations consumed by distributed networking infrastructure
• Develop business logic for network configuration and orchestration, working with networking concepts such as VLANs, VRFs, VXLAN, network topology, and TCP/IP-based communication
• Build software that manages and distributes configuration across networking devices and systems, with an understanding of how control-plane decisions interact with the underlying data plane
• Work with network configuration models and interfaces, including YANG or similar standards used to configure and manage network infrastructure
• Integrate third-party components and internal services into Cisco security platforms
• Collaborate with data plane and platform engineering teams to deliver end-to-end feature functionality
• Contribute to architecture discussions, feature design, and technical execution for new security capabilities
• Ability to collaborate effectively with peers across a geographically distributed team, with regular overlap during Pacific Time (PST/ PDT) business hours

Requirements:

• • Bachelor's degree + 8 years of related software engineering experience, or Master's + 6 years of related experience, or PhD + 3 years of related experience
• • 5+ years of development experience in languages such as Go, or C++
• • Experience developing software in Linux environments
• • Experience developing software for networking or network infrastructure products, with knowledge of networking concepts such as TCP/IP, VLANs, VRFs, VXLAN, network topology, routing/switching, or control plane/data plane interactions
• • 5+ years of professional Go development experience
• • Experience designing and developing APIs using REST, gRPC, or Protocol Buffers
• • Experience working with Kubernetes-based applications, including developing, deploying, debugging, or operating software running in Kubernetes environments
• • Familiarity with Kubernetes concepts such as CRDs, Kubernetes APIs, controllers, RBAC, or secrets management
• • Experience developing software for switching, routing, firewall, or other network infrastructure platforms
• • Familiarity with network configuration and management technologies such as YANG, NETCONF, telemetry, or similar infrastructure configuration frameworks
• • Experience working effectively in a remote or distributed team environment
