How you’ll make an impact

As a Senior Security Network Engineer, you’ll be hands-on solving problems in Xero’s corporate environment with a focus on Firewalls, SASE, ZTNA, WiFi, LAN Switching and WAN. You’ll become deeply familiar with the capabilities of our vendors to build and support modern and adaptable security services that will delight our customers. We run mission-critical infrastructure, and you’ll build resilient and scalable networks. You can deliver robust network security solutions across both BAU and project-based initiatives in a fast-paced dynamic environment.

Automation will be the standard for you, and you’ll seek new and interesting ways to reduce our operational overheads. Most importantly, you’ll be a team player and get to work with an awesome group of engineers in an amazing and unique working environment.
