Senior Systems Engineer / MSP Technical Lead

Salary: $125,000–$145,000 plus super

About the role

Macarthur Managed IT is looking for a Senior Systems Engineer / MSP Technical Lead to become a key technical and operational member of our growing team.

This is a senior, hands-on position for someone with strong technical aptitude who is ready to take ownership of complex incidents, projects and technical service delivery. You will work across Microsoft 365, Intune, Azure, Windows Server, networking, cybersecurity and automation, acting as a senior escalation point for our team and clients.

You will work directly with the business owner to improve service delivery, develop technical standards, mentor other team members and help coordinate the day-to-day technical operations of the MSP.

This opportunity may suit an experienced MSP engineer who lives in the Macarthur region and wants to avoid commuting into Sydney. We are also open to a capable corporate IT engineer who wants to broaden their experience by moving into the varied and fast-moving MSP environment.

The successful candidate will initially work from our Narellan office during onboarding and probation. Once established, the position will transition primarily to working from home, with occasional attendance at the Narellan office and client sites.

Candidates living in the Macarthur region or within practical travelling distance of Narellan are preferred.

Key responsibilities

• Own and resolve complex technical incidents through to completion.

• Act as a senior escalation point for other team members and clients.

• Design and deliver Microsoft 365, Intune, Azure, server, network and cybersecurity solutions.

• Scope, plan and deliver infrastructure, cloud and migration projects.

• Administer Microsoft 365, Entra ID, Intune, Exchange Online, SharePoint and related services.

• Support Windows Server, Active Directory, Group Policy, DNS, DHCP and virtualised environments.

• Configure and troubleshoot firewalls, routing, switching, VLANs, wireless networks and VPNs.

• Identify security risks and implement practical improvements across client environments.

• Use PowerShell and other tools to automate repetitive work and improve consistency.

• Investigate recurring problems and implement lasting solutions.

• Develop technical standards, procedures and supporting documentation.

• Mentor other team members and assist with difficult escalations.

• Communicate clearly with clients, vendors and non-technical stakeholders.

• Help coordinate technical priorities, project work and service delivery.

• Attend client sites when required.

About you

You are a capable technical generalist who enjoys understanding how systems work and solving problems that do not always have an obvious answer.

You take ownership of outcomes, communicate clearly and remain methodical during difficult incidents. You are comfortable working independently, but you also document and share your knowledge so that the entire team benefits.

Your exact number of years in the industry is less important than the level at which you can operate. We value demonstrated capability, sound judgement, initiative, personal responsibility and the ability to learn unfamiliar technologies quickly.

You may already work in an MSP, or you may have developed broad infrastructure experience within a corporate IT department and be ready for greater variety and responsibility.

Essential experience and capabilities

• Broad professional experience supporting business IT environments within an MSP, corporate IT department or a combination of both.

• Strong Microsoft 365 administration and troubleshooting capability.

• Practical experience with Microsoft Intune, Entra ID and endpoint management.

• Strong Windows Server, Active Directory, Group Policy, DNS and DHCP knowledge.

• Sound networking knowledge, including routing, VLANs, VPNs, firewalls and wireless networks.

• Experience taking ownership of infrastructure, cloud or migration projects.

• Working knowledge of modern cybersecurity controls and practices.

• Scripting or automation experience, preferably using PowerShell.

• Strong analytical and troubleshooting ability across multiple technology layers.

• Ability to explain technical issues clearly to technical and non-technical people.

• Ability to manage competing priorities without losing ownership of work.

• Willingness to mentor colleagues and contribute to operational improvements.

• Current Australian driver licence and ability to attend client sites when required.

• Australian working rights.

Highly regarded

• Previous experience working for an MSP.

• Experience as a senior escalation engineer or technical lead.

• Microsoft, Fortinet, Cisco, Azure or other relevant certifications.

• Experience with Microsoft Defender or comparable security platforms.

• Experience with RMM, PSA and IT documentation platforms.

• Experience with backup, disaster recovery and business continuity.

• Exposure to macOS and Apple device management.

• Experience with SQL Server, C#, APIs or systems integration.

What we offer

• A salary of $125,000–$145,000 plus superannuation, based on demonstrated experience and capability.

• A senior and influential role within a growing local MSP.

• An initial office-based onboarding period in Narellan, transitioning to primarily working from home.

• Minimal on-call/after hours requirements, with any required after-hours work paid at overtime rates.

• Reimbursement for approved travel to client sites.

• A company-supplied laptop and mobile phone.

• Variety across cloud, infrastructure, cybersecurity, networking and automation.

• Direct access to decision-makers without unnecessary corporate layers.

• Meaningful ownership of projects, technical standards and client outcomes.

• Support for relevant training and professional development.

• The opportunity to help shape and improve the technical operations of the MSP.

How to apply

Please submit your résumé together with a short introduction covering:

• The technical environments you currently support.

• A difficult technical problem you personally investigated and resolved.

• A project you have owned or played a major role in delivering.

• Something you have automated, standardised or substantially improved.

• Why this position interests you.

Applications are encouraged from experienced MSP engineers and capable corporate IT engineers who are ready to broaden their experience and take on greater technical and operational responsibility.
