IT Operations - Internal Systems & Infrastructure

Box Advisory Services is a boutique Sydney-based accounting and advisory firm, founded in 2016, with a team of around 40 across Sydney and offshore. We help SME clients across tax, compliance, CFO/virtual CFO advisory, property structuring, and bookkeeping. As we scale, we're bringing IT operations in-house and building the internal function that will support the firm through its next phase of growth.

About the role

We're transitioning away from our external MSP and need someone to own IT operations end to end for a ~50-endpoint Microsoft 365 environment. This is a hands-on role covering identity, endpoints, security, backup, cloud, telephony, vendor management, and end-user support — effectively absorbing our MSP's full scope, plus the strategic ownership that comes with being an internal hire.

You'll be the firm's sole IT point of contact, working closely with leadership to validate, document, and improve our environment as we move off external support.
Key responsibilities

Microsoft 365, identity & endpoints

• Administer Entra ID, Exchange Online, SharePoint, OneDrive, and Teams; own user lifecycle, conditional access, MFA, and group/role management

• Run the Intune and Autopilot estate across ~50 endpoints: enrolment, compliance, configuration profiles, app deployment, and Windows Update rings

• Manage joiner-mover-leaver processes end to end, including device provisioning, retirement, and data preservation

Security & backup

• Operate our security stack (EDR, email security, Microsoft Defender); triage alerts, investigate incidents, and drive remediation

• Own backup posture across Microsoft 365 and infrastructure; monitor jobs, test restores, and maintain a documented DR/BCP plan

• Maintain security documentation aligned to the Essential Eight (or equivalent); support audit and compliance requests

Cloud, network & telephony

• Administer existing Azure and/or AWS workloads: IAM, networking, monitoring, cost, and security baselines

• Maintain office network and Wi-Fi; coordinate ISP and carrier issues

• Administer our cloud PBX/VoIP platform (Teams Phone or equivalent): users, call routing, numbers, and vendor liaison

Support, vendors & governance

• Act as the IT point of contact for staff, with clear SLAs and ticket hygiene; maintain a lightweight internal knowledge base

• Manage IT vendors and resellers (Microsoft CSP, hardware, security, SaaS); maintain a single licence register, manage renewals, and benchmark spend

• Maintain core IT documentation: network diagrams, runbooks, asset register, and internal policies

• Report monthly on tickets, security posture, backup health, and spend

What you'll bring

Required

• 3+ years hands-on experience in IT operations, sysadmin, or MSP engineering in a Microsoft-centric environment

• Production experience with Microsoft 365, Entra ID, Intune/Autopilot, and Defender (or equivalent EDR/email security)

• Working knowledge of Azure or AWS at an operational level (IAM, networking, cost, monitoring)

• Solid networking fundamentals, backup operations, and vendor/licence management experience

• Strong written communication and a service mindset — comfortable being the sole IT point of contact

• Full Australian working rights, and able to be on-site in our Sydney office as required

Highly regarded

• Prior MSP experience across multiple SME clients

• Microsoft certifications (MS-102, AZ-104, SC-200, MD-102) or AWS equivalents

• PowerShell scripting for routine automation

• Experience standing up an internal IT function while transitioning away from an external MSP

• Familiarity with the Essential Eight, ISO 27001, or SOC 2

What success looks like in your first 90 days

• Full handover from the outgoing MSP completed and documented

• Tenant, endpoint, and security baselines validated, with any gaps closed

• Backup and restore testing running on a documented schedule

• Licence register cleaned up and the next renewal cycle optimised

What we offer

• Salary range — $95,000 - $110,000 + super, depending on experience

• The opportunity to build an internal IT function from the ground up, with real ownership and autonomy

• A close-knit, growing firm where your work has direct visibility with leadership
