We’re ISO 9001 and ISO 27001 certified, Microsoft-centred and automation-led, and we deliver to documented standards rather than one-off builds. We’re a genuinely single-accountable provider: from Microsoft 365 and security through to Cisco Meraki networking and telephony on our own voice platform. The opportunity We’re growing our engineering team and looking for a Senior Systems Engineer to support and mature client environments — including semi-remote regional sites where reliable connectivity is safety-critical, not just a convenience. This is a remote-first role for someone based in regional Victoria: you’ll work primarily from home, with regular travel to client sites across regional Victoria (a company vehicle is provided for business use), plus the option to use our office when it suits. You’ll bring strong hands-on/onsite instincts to a role that’s delivered mostly remotely and by automation. You’ll be the kind of engineer who owns complex issues end to end, documents as they go, and lifts the standard of every environment they touch. Requirements What you’ll work across Microsoft 365 & identity — Exchange Online, SharePoint, Teams, OneDrive; Microsoft Entra (Conditional Access, MFA, SSO, joiner/mover/leaver). Endpoint & SOE — Microsoft Int
