The Position

As a Linux Infrastructure Engineer at Nexigen Digital, you will be part of a close-knit team responsible for the servers, networks and hardware that keep hundreds of thousands of Australian websites, inboxes and businesses online. We’re looking for someone who loves Linux, takes pride in a well‑built and well‑secured server, is proactive, goal oriented and possesses excellent problem solving skills.

• Writing Bash and Python scripts to automate the boring stuff
• Taking your turn on our on‑call roster, and helping get things back online quickly when the unexpected happens

• Has hands‑on experience with hypervisors and virtual machine management
• Is comfortable working with physical server and data centre hardware

• Can write and maintain scripts in Bash and Python
• Has a strong understanding of system security and hardening principles
• Is calm and methodical under pressure
• Is happy to be part of an on‑call roster
• Has excellent written and verbal communication skills, and is keen to share knowledge with the team

Handy things to have (or are able to learn)

• Experience deploying containerised environments from the ground up
• Experience managing database clusters such as MariaDB/Galera
• Experience managing email platforms and mail transfer agents (MTAs), including spam filtering
• Experience with Ceph or other distributed storage
• Familiarity with DevOps tooling, such as CI/CD pipelines, monitoring and infrastructure as code
• Experience managing email servers and spam filtering platforms
