Ever fixed a kernel panic before your first coffee?
Then you might be exactly who we're looking for.
The Opportunity
Five nines.
That's roughly 5 minutes of downtime a year, and we'd rather spend those minutes on a coffee run than an outage.
Access4 is looking for a Senior Infrastructure Engineer to own the backend environments that power our platform.
When a problem is gnarly, obscure or buried deep in the kernel, you're the one people call, and you enjoy that.
If you like Linux, you're calm when others panic, and you believe valuable automation is a form of self-care, keep reading.
What You'll Be Doing
Looking after our backend systems every day and keeping them healthy
Finding what's fragile and making it resilient, then doing it again
Being the go-to infrastructure expert for engineering and the wider Access4 team
Getting stuck into engineering and R&D; work that shapes where the business goes next
Taking your turn on call for after-hours events, and staying cool when the pager goes off
Staying steady under pressure so critical systems stay up
Bringing structure and discipline to both quick fixes and long-term projects
What You'll Bring
The essentials:
A Bachelor's degree in IT or a related field
Full working rights in Australia (we can't offer sponsorship)
5+ years in Linux administration, down to the kernel and module level
5+ years managing on-premises environments (real servers, real racks)
3+ years with Docker or other containerisation tech
3+ years with Ansible or similar automation tools
3+ years developing in Python
3+ years with virtualisation technologies




Solid knowledge of TCP/IP network stacks and monitoring systems
Sharp problem-solving and analytical skills, and the ability to explain what you found clearly, in writing and out loud
Other programming languages besides Python
Database administration experience (MySQL, PostgreSQL or similar)
VoIP know-how, especially SIP
