Principal Network Architect

Position Summary

The Principal Network Architect will play a key role in evolving and modernizing the F5 corporate network. Using a zero trust and advanced network segmentation approach this role will focus on designing secure scalable efficient network solutions that span a hybrid on-premise and cloud ecosystem.. Design principles must span a diverse array of environments and use cases including manufacturing centers global office locations a global remote workforce datacenters and multiple IaaS providers. This role will also play a critical role in the F5 on F5 program providing product feedback to F5 product teams and helping design and implement customer zero implementations of F5 products and appliances centering designs on F5 products and services where applicable. The Network Architect role will ensure that the F5s infrastructure adheres to the highest standards of security reliability and performance while incorporating advanced network security practices.

The ideal candidate will have strong technical expertise in enterprise network architecture and design extensive experience with zero trust principles and a deep understanding of network segmentation using F5 Palo Alto Cisco and ZTNA technologies. They should have a deep knowledge of the network vendor market understanding capabilities of a wide variety of tools to solve routing security and performance issues as well as providing competitive analysis of F5s product stack. Additionally the candidate will be proficient in deploying and managing network security tools such as secure web gateways Cloud Access Security Broker (CASB) solutions and other technologies for data loss protection and threat mitigation.

This role will have hands-on aspects including building proof-of-concepts assisting with reference implementations and troubleshooting designs during implementation.
