through resolution, ensuring SLA commitments are met.\n\nProvide clear and timely updates to clients, including technical findings, progress and next steps.\n\nDeliver remote and onsite support, including troubleshooting at client premises.\n\nCoordinate with vendors, ISPs and third-party providers to resolve technical issues.\n\nMaintain accurate ticket notes, troubleshooting records and resolution documentation.\n\nIdentify recurring problems and recommend improvements to prevent repeat incidents.\n\nProjects & Infrastructure SupportAssist with server migrations, network refreshes, firewall replacements, wireless deployments and office infrastructure projects.\n\nConfigure and deploy switches, firewalls, wireless access points, servers and endpoint devices.\n\nSupport rack-and-stack activities, cabling, equipment installation and onsite deployment work.\n\nFollow implementation plans, change procedures and rollback requirements.\n\nPerform post-implementation testing and validation.\n\nWork alongside senior engineers and Technical Architects to deliver project tasks.\n\nTeam CollaborationProvide technical guidance to junior Service Desk engineers.\n\nContribute to knowledge base articles, SOPs and technical documentation.\n\nCollaborate with Service Delivery, Projects and Account Management teams.\n\nMaintain accurate time entries and work records in the ticketing system.\n\nRequirements\nMinimum 3 years of hands-on experience in IT infrastructure support, preferably in an MSP or multi-client environment.\n\nStrong working knowledge of Windows Server, Active Directory and Microsoft 365 administration.\n\nPractical experience troubleshooting network connectivity, switches, firewalls, VPNs and wireless networks.\n\nFamiliarity with technologies such as Cisco Meraki, Fortinet, Sophos, Aruba or equivalent platforms.\n\nExperience with VMware, Hyper-V, backup solutions and endpoint security tools.\n\nAbility to independently investigate and resolve L2 incidents.\n\nComfortable providing both remote and onsite support.\n\nGood written and verbal communication skills, with the ability to explain technical issues clearly to clients.\n\nStrong organisational skills, ownership and attention to detail.\n\nAdvantageous Experience\nPrevious experience working in a Managed Service Provider (MSP).\n\nMicrosoft 365, Azure or Intune certifications.\n\nCCNA or equivalent networking certification.\n\nFortinet, Sophos or Cisco Meraki certifications.\n\nITIL Foundation certification.\n\nExperience with ServiceNow or similar ITSM platforms.\n\nExposure to infrastructure migrations, network deployments and project implementation.\n\nWhat We're Looking For\nBeyond technical skills, we value engineers who take ownership of their work, communicate proactively and approach problems methodically.\nYou should be comfortable working independently while knowing when to collaborate or escalate, and be willing to support both day-to-day service delivery and infrastructure projects.\nSkills\nIncident Support, Microsoft 365, Ownership, Technical Troubleshooting,
