We are seeking an experienced Infrastructure Engineer to join a stable IT team in Sydney. This is a hands-on engineering role, ideal for someone who enjoys being close to the technology and taking ownership of core infrastructure services. While the immediate focus is on delivery and remediation, there is a progression pathway into an Infrastructure Architect role over time.

You will play a key role in strengthening infrastructure security, supporting critical network and Microsoft environments, and delivering key improvement initiatives across the business. This includes working on remediation activities following a recent penetration test, supporting a major SD-WAN rollout, and helping uplift overall infrastructure standards.

Responsibilities Include:

- Provide hands-on support, maintenance, and improvement of core infrastructure services.
- Manage and support enterprise network and Microsoft-based environments.
- Lead remediation work following recent penetration testing findings and security assessments.
- Implement and maintain secure configuration standards and infrastructure baselines.
- Support and enhance Active Directory, Windows Server, DNS, DHCP, Group Policy, and Microsoft 365 environments.
- Contribute to disaster recovery planning, testing, and resilience improvements.




- Provide senior-level troubleshooting and escalation support across infrastructure domains.

Experience needed:

- We're ideally looking for an all-round infrastructure engineer who enjoys working across both network and Microsoft environments, with a focus on hands-on delivery.
- Hands-on experience across networking and Microsoft services.
- Experience working in environments with Active Directory and Windows Servers.
- Exposure to infrastructure security, hardening, and remediation work.
- A practical, delivery-focused mindset with strong troubleshooting ability.
- Experience working with Cisco, FortiGate, HP, or similar enterprise network technologies.
- Multi-site workplace experience is highly desirable.

What's on offer

This is an opportunity to join an organisation undertaking significant infrastructure uplift work. You will play a key role in strengthening security, improving network and core services, and contributing to major infrastructure projects - while remaining deeply hands-on in your day-to-day work. Over time, you will be given increasing exposure to infrastructure design, architecture decision-making, and strategic initiatives as you grow within the role.
