Since 2006, we've been transforming Perth's IT landscape by putting our core values of enablement, leadership, and success at the heart of everything we do. Recognized as a CRN FAST 50 finalist in 2018, 2024, 2025 & 2026; we've consistently proven our ability to grow, innovate, and deliver exceptional IT solutions.\nWe believe in empowering our team to reach new heights. Our unique internal culture cultivates talent, encourages leadership, and celebrates success. When you join Epic IT, you're not just taking a job - you're embarking on a career journey with a company that's passionate about technology, committed to our people, and dedicated to making a real impact in the IT industry.\nLooking to be part of a forward-thinking team that's reshaping IT solutions in Perth? Epic IT is your destination for professional growth, cutting-edge technology, and meaningful work.\nWhat We Offer\nCompetitive salary with clear progression criteria\nFunded certification paths - Microsoft, security, cloud, networking, voice\nDirect mentoring from Solutions Architects, with a defined path to Solutions Architect\nHybrid working - home-based day to day, with 3-4 days in our North Perth office or Brisbane office, and site visits for hardware deployments and complex client work. This isn't a remote-only role; the client site work is real and regular.\nAccess to lab environments and test systems, and a modern tooling stack\nA collaborative team where asking questions is encouraged, with regular knowledge-sharing sessions\nAbout the role\nEpic IT is a Perth-based, AI-first MSP running production infrastructure for around 72 clients across cloud, networking, telephony and security. An MSP holds the keys to every client it manages, so our own environment has to meet a higher bar than any of theirs. This role makes sure it does.\nThe work splits roughly 50/50. Half is Epic IT’s internal infrastructure: our Microsoft 365 tenant, identity, devices, network, and the platforms the service team uses every day. The other half is security: our ISO 27001 controls, threat detection and response, and security uplifts for clients.\nIt suits someone who has been strong at L2 or early L3 and is ready to own a security and infrastructure brief. We don’t expect a perfect match on every line below. If you cover most of it and your fundamentals are solid, we want to hear from you.\nWhat we offer\nCompetitive salary with clear progression criteria\nFunded certification paths in Microsoft security and identity, cloud and networking\nMentoring from our senior engineers and Solutions Architects, with a path into senior security or infrastructure roles\nBased in Perth or Brisbane, hybrid, with occasional client site visits\nTest tenants and a modern tooling stack\nA team where asking questions is normal, with regular knowledge-sharing sessions\nWhat you’ll do\nInternal infrastructure.Run Epic IT’s own Microsoft 365 and Entra ID tenant: identity, Conditional Access, Intune, Exchange Online, SharePoint and Teams. Look after our internal network, firewalls and remote access, plus the PSA, RMM, documentation and backup platforms the service team depends on. Set up accounts and devices for new starters, and be the person staff come to when something internal breaks. Write PowerShell for provisioning, reporting and the maintenance jobs nobody should be doing by hand.\nSecurity and compliance.Keep our ISO 27001 controls working, evidence collected and policies current, and help prepare for audits. Manage endpoint protection, application control and threat detection across our environment and our clients’. Triage alerts, run incident response, and write up what happened and what changed. Deliver client security uplifts: Essential Eight controls, MFA and Conditional Access, Defender, and security awareness training. Run access reviews and check vulnerability and patch compliance. You’ll work alongside our security officers in Clark, Philippines.\nDocumentation.Keep runbooks, configuration baselines, change records and network diagrams current for everything you own. Train the service team on the controls you put in place.\nTechnical requirements\nCore skills:\n2-4 years hands-on in an MSP or internal IT role\nMicrosoft 365 and Entra ID administration, including Conditional Access, Intune and Exchange Online\nNetworking fundamentals: TCP/IP, DNS, DHCP, VLANs, routing, VPNs, firewall rules\nWorking knowledge of security tooling such as EDR, MDR or SIEM alerting, and email security\nWindows Server and Active Directory, including hybrid identity\nPowerShell you write yourself, not just scripts you’ve run\nClear written notes. If you can’t explain what you changed, we can’t audit it\nNice to have:\nSC-200, SC-300, MS-102 or AZ-104\nExposure to ISO 27001, Essential Eight or NIST CSF\nIncident response experience, even on a small scale\nApplication allowlisting or MDR platform experience\nAzure infrastructure experience\nThe team\nYou’ll work with senior engineers and Solutions Architects who know their stuff, plus a service team that will lean on you. Asking questions is normal here, and we hold regular knowledge-sharing sessions.\nWhat this role isn’t\nThis isn’t a helpdesk role, and you won’t be working the client phone queue. We don’t micromanage, so you’ll need to run your own priorities and make sound calls without a script. It isn’t fully remote either, because some of the work happens in the office and on client sites.","description_format":"text","description_chars":5641,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Hybrid work"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Managed IT Services (MSP)"],"lifecycle":[{"event":"open","at":"2026-11-09T04:34:17Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":35,"reasons":["conf:1","win:early","comp:junior"],"computed_at":"2026-11-09T06:03:00Z"},"pay":null,"html_url":"https://alion.io/job/epic-it-solutions-security-internal-infrastructure-engineer","json_url":"https://alion.io/job/epic-it-solutions-security-internal-infrastructure-engineer.json","meta":{"generated_at":"2026-11-09T09:51:49Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9863,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":674365},"rest":"https://alion.io/mcp/rest/get_company?id=674365"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fepic-it-solutions-security-internal-infrastructure-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fepic-it-solutions-security-internal-infrastructure-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fepic-it-solutions-security-internal-infrastructure-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/epic-it-solutions-security-internal-infrastructure-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fepic-it-solutions-security-internal-infrastructure-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3952028}},{"tool":"search_jobs","arguments":{"company":"epic-it.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3952028},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
