Cloud Support Engineer

About the roleOur client, a Sydney-based managed services provider, needs a genuinely senior infrastructure engineer for an ongoing casual based contractor based from our Sydney based CBD office.
We are looking for someone who can walk into an unfamiliar environment, work out how it is actually built (not how the documentation says it is built), and stabilise it. You will be working across multiple client environments, so the ability to context-switch cleanly and communicate technical risk to non-technical stakeholders matters as much as the hands-on skill.
Immediate start available for the right person.
What you'll be doingDiagnosing and resolving complex Windows Server and Active Directory issues — DC design and recovery, FSMO role placement and seizure, Group Policy troubleshooting, DNS and DHCP at a "why is replication broken" levelDesigning and troubleshooting identity across Entra ID and hybrid environments — hybrid join, Conditional Access policy, SSO/SAML/OAuth federation, MFA rollouts and break-glass account designSupporting and improving Microsoft 365 estates — Exchange Online mail flow and transport rules, SharePoint and Teams architecture, Purview fundamentals, and advising on the licensing implications of design decisionsWorking across client networks — VLANs, routing, firewall policy (Fortinet, Sophos and Meraki are common), site-to-site and SSL VPN — with enough packet-level capability to prove where a problem isn'tOwning backup and disaster recovery outcomes — Veeam or equivalent, genuine restore testing, immutability, 3-2-1-1-0, and holding credible RPO/RTO conversations directly with clientsLifting security posture — EDR, patch and vulnerability management, hardening baselines and Essential Eight alignmentAutomating the repetitive work — PowerShell as a daily tool for remediation, bulk change and reporting, not as a line on a CVContributing to Azure work as it comes up. IaaS, VNets, ExpressRoute/VPN, Azure Files and migration projects (AWS exposure useful but not essential)Documenting what you build and fix so the rest of the team can support it after you leave
What we need from youDemonstrable senior-level infrastructure experience, ideally gained in an MSP or multi-client environmentDeep Windows Server and Active Directory troubleshooting ability — you have recovered a domain, not just joined machines to oneStrong Entra ID and Microsoft 365 administration, including hybrid identity and Conditional AccessPractical networking and firewall skills across at least one major vendor platformReal backup and DR experience, including having run restores under pressureWorking PowerShell scripting capabilityAzure IaaS exposure — enough to be useful on migration and infrastructure workClear written and verbal communication, and the confidence to explain risk to a client and hold the line on itAustralian working rights
Nice to have: Essential Eight assessment experience, Veeam certification, relevant Microsoft certifications (AZ-800/801, SC-300), AWS exposure.
