Job description

Network & Infrastructure Engineer (Tier 3)

Location: Sydney

Work Arrangement: 5 Days Onsite

Employment Type: Permanent

The Opportunity

We're partnering with a well-established financial services organisation that is investing heavily in its internal technology capability and infrastructure landscape.

As part of this growth, we're seeking a Network & Infrastructure Engineer (Tier 3) to become the senior technical escalation point across infrastructure, networking, cloud, and security. This is an opportunity to join a business that is bringing key technology functions in-house and looking for someone who enjoys ownership, accountability, and influencing technical direction.

This role goes beyond traditional support. You'll play a key part in maintaining, improving, and modernising the organisation's technology environment while partnering closely with technology leadership on infrastructure and security initiatives.

What You'll Be Doing

• Act as the Tier 3 escalation point for infrastructure, cloud, network, and security-related issues.
• Manage and optimise Azure networking (VNet/NSGs), Microsoft 365, Entra ID, Intune, and associated Microsoft technologies.
• Support and enhance enterprise networking environments, including firewalls, VPNs, switching, and connectivity.
• Own infrastructure security, vulnerability management, endpoint protection, and compliance initiatives.
• Lead backup, disaster recovery, and business continuity activities.
• Develop automation and operational efficiencies through PowerShell scripting.
• Work closely with vendors, MSP partners, and internal stakeholders to drive service improvements.
• Contribute to infrastructure projects, platform upgrades, and future-state technology planning.
• Create and maintain technical documentation, standards, and operational processes.

What We're Looking For

• Strong experience in infrastructure engineering, systems engineering, or network engineering roles.
• Hands‑on expertise across Microsoft Azure and Microsoft 365 technologies.
• Strong networking knowledge covering routing, switching, VPNs, firewalls, and WAN/LAN environments.
• Experience with Entra ID, Intune, Active Directory, and endpoint management.
• Exposure to security technologies such as CrowdStrike, ThreatLocker, Huntress, Defender, or similar tools.
• Scripting and automation experience using PowerShell.
• Experience supporting backup and disaster recovery solutions.
• Strong troubleshooting, stakeholder engagement, and documentation skills.
• Ability to work independently and take ownership of a complex technology environment.

Why Consider This Opportunity?

• Significant influence over the technology environment.
• Broad technical ownership across infrastructure, cloud, networking, and security.
• Opportunity to help shape an internal technology function as responsibilities transition from an MSP model.
• High visibility with senior technology and business stakeholders.
• Stable and growing organisation with a strong investment in technology.
• A role suited to engineers who enjoy building, improving, and leading outcomes rather than simply maintaining BAU operations.

If you're an experienced infrastructure professional looking for a role where you can genuinely make an impact, we'd love to hear from you.
