Senior Software Engineer, Control Plane; Go; Hypershield

Position: Senior Software Engineer, Control Plane (Go) - Hypershield
The application window is expected to close on: 09/15/2026

*
* Note:

** This is a remote U.S. based role, requiring work within the Pacific Time Zone.

** Meet the Team*
* Join Cisco's Cisco Hypershield team, where we are building the next generation of distributed security infrastructure for modern networking environments. Within Hypershield, the Smart Switch team develops foundational security capabilities that extend across multiple Cisco platforms, including switching, routing, and firewall systems.

This team is responsible for core control plane software that enables policy configuration, deployment workflows, logging, visibility, and feature orchestration across a shared security architecture used by products spanning Cisco systems networking portfolios, including Nexus, Catalyst, and emerging smart switch platforms.

The work here is highly foundational: features built by this team influence security behavior across multiple Cisco networking products and future infrastructure platforms.

** Your Impact*
* In this role, you will design and develop control plane software for security features used in smart switching platforms and distributed firewall systems. You will contribute to core feature development from design through implementation, with a focus on APIs, policy orchestration, and secure service integration.

You will work closely with engineers across control plane, data plane, and platform teams to deliver scalable capabilities that support deployment, observability, and policy enforcement across distributed environments.

** What*
* ** you'll*
* ** do*
* + Design and develop control plane features for network security products using Go in Linux-based environments

+ Build and maintainAPIs andcloud-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.

** Minimum Qualifications*
* + 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.

** Preferred Qualification*
* ** s*
* + 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
