Full Job Description

Who is NextGen?

NextGen is a leader in Australian financial technology, providing innovative SaaS solutions to streamline mortgage processing and Open Banking for the nation's lenders, brokers and customers. Find out more about us here.

What does an Operations Engineer do at NextGen?

Join our team as an Operations Engineer and take ownership of the stability and performance of our production environments. You will ensure NextGen’s systems run smoothly and meet strict availability requirements by detecting issues, responding rapidly, and driving the resolution of service-impacting incidents. This role is ideal for a technical specialist who thrives on solving unplanned technical challenges, performing deep root-cause analysis, and continuously recommending improvements to platform reliability and monitoring.

Key Responsibilities

Investigate and resolve unplanned technical issues within SLA as the Level 3 escalation point to ensure timely solutions and minimal service impact.
Monitor system health to ensure performance stays within requirements; proactively identify and recommend opportunities to improve platform availability.
Manage error rates down by identifying true root causes and proposing technical changes or process improvements.
Identify opportunities to enhance system monitoring, alerting, reliability, and the comprehensive Knowledge Base/playbook library.
Participate in the execution of disaster recovery protocols and other critical infrastructure tests to ensure system resilience.

Essential Skills & Experience

Solid experience with PowerShell, Bash, or Python (specifically for troubleshooting and adapting existing scripts).
Hands-on experience managing and maintaining both Microsoft Windows and Linux server environments.
Strong knowledge of network protocols (TCP/IP, VLAN, routing) and proven experience in troubleshooting complex networking issues.
A proactive approach to detecting issues and driving the resolution of unplanned technical incidents.

PLEASE NOTE: Due to the nature of this role we are only able to consider Australian citizens and permanent residents.

What we offer

Growth: Opportunities for professional development, training and clear career pathways across operations, platform and engineering roles.

Family Focus: Flexible working arrangements to support work-life balance in a collaborative and inclusive environment.

Supportive Culture: Join a team that values learning, psychological safety and the opportunity to make a real impact on the reliability and scalability of products used by our customers.

How to apply

If you are excited to help run and improve mission-critical platforms in a fast-growing fintech, please apply with your CV and a short cover letter outlining relevant experience, key projects or contributions to operational excellence.
