We are partnering with a leading organisation to find a skilled Application Support Analyst ready to own the reliability of critical business software. You will be the first and second line of defence — fielding complex user issues, digging into root causes, and seeing fixes through to resolution.

This is a collaborative, high-visibility role where you will work closely with Development, Design, Product, and Account Management teams to deliver outstanding outcomes for end users.

• Write and execute SQL queries to investigate data issues, validate fixes, and produce management reports
• Log, prioritise, and manage incidents and service requests through to resolution within an ITIL-aligned service desk framework
• Collaborate actively with Development, Design, Product Owner, and Account Management teams to coordinate fixes, releases, and user communications
• Deliver clear, customer-focused communication at every stage — keeping users informed and confident throughout an incident
• Maintain accurate documentation including runbooks, known errors, and knowledge base articles
• Monitor application health and proactively identify trends before they become incidents

What we’re looking for:

Essential requirements

• Australian citizenship — required for security clearance eligibility
• Demonstrated L1 and L2 application support experience with business software, including troubleshooting complex user issues, root cause analysis, and implementing solutions.
• Good knowledge of Linux
• Solid SQL skills — writing queries, joins, and data investigation to support troubleshooting and reporting
• Excellent verbal and written communication skills with a genuine customer-service mindset
• Service desk experience working within an IT Service Desk or Service Management framework (ITIL fundamentals preferred) — including logging, prioritising, and managing incidents and service requests through to resolution
• Proven ability to collaborate across teams — Development, Design, Product Owner, Account Management, and other stakeholders

Highly regarded

• ITIL Foundation certification or equivalent service management qualification
• Experience reading and interpreting application logs and error traces
• Scripting ability — PowerShell, Python, or Bash
• Exposure to cloud platforms such as Azure or AWS\
• Familiarity with ticketing tools such as ServiceNow or Jira
