About the role

Katalon's IT & Digital Transformation team runs the internal technology for our people across Vietnam, the US and remote locations. We are a small team that works agent-first: we run IT through APIs, scripts and AI agents, not through click-ops and ticket queues.

We are looking for an engineer to own IT Operations in our HCMC office - the service desk, identity and devices, onboarding and offboarding, and the office network and server room. You will be the go-to owner for this domain, run projects on your own, and use automation and AI to keep a large scope manageable.

We hire for growth. You likely started on the service desk and have already begun to own sysadmin work: a firewall rule, the office WiFi, a VPN, a server, the backups. This role gives you the full scope and the title to match. You do not need to know all of it on day one; you need to want it and learn fast.

What you will own

From day one

• Service desk: the IT request queue, floor support, meeting-room and event AV.
• Onboarding and offboarding: accounts, devices, access, licences and data handover - complete and evidenced.
• Identity: Google Workspace administration.
• Devices: a Mac-first laptop fleet with some Windows, managed through MDM; endpoint security and the hardware asset register.
• Network and server room, first line: collect the data, find the cause, make safe changes with a written plan and a rollback. Enterprise firewall, WiFi and switching; virtualisation, storage, power and backups.
• On-call: office emergencies; paid overtime when an incident or event needs it.

Within your first six months

• Network and server room, full ownership: firewall policy, WiFi, VPN and backups - end to end, under change control.
• Vendors: day-to-day owner for IT vendors and service providers - quotes, tickets, invoices, renewals.
• Compliance: first-line security-compliance evidence (for example SOC 2): access reviews and device controls.
• Licences: SaaS seat hygiene and renewals.
• Cloud housekeeping: OAuth clients, API access, billing and access for our cloud tenants.
• Physical security: office access control and cameras.
• Documentation and automation: runbooks for the systems you own; automate recurring service-desk and lifecycle work.

What we need from you (must-have)

• 3+ years in IT, including service-desk work, with growing ownership since then (things you built, migrated or ran, not only tickets).
• Hands-on sysadmin exposure in at least one of: firewall, WiFi, VPN, servers, backups. You can tell the story of a problem you fixed yourself.
• The drive to grow into a sysadmin / IT-ops owner role.
• You enjoy service work. Users come first. This role keeps the service desk; it grows your scope, it does not take you away from users.
• Workspace admin (Google Workspace, or Microsoft 365 / Entra ID and a will to switch) and identity basics (SSO/SAML, OAuth, least privilege).
• MDM experience (Jamf, Intune or similar) and device-fleet support.
• Real AI use, with examples (MUST). You use AI tools in your daily IT work to troubleshoot, script, document and automate. Not for show, and not only when someone makes you. Your application MUST include 1-2 short examples: the problem, how you used AI, and the result.
• Scripting in Bash, Python or PowerShell.
• Careful change habits: one change at a time, a rollback ready, a written record.
• Root-cause mindset: you prove a cause with data before you call it.
• High agency: you find and close problems without being chased.
• Good written and spoken English; Vietnamese for local vendors.
• 100% on-site in our HCMC office. Work starts at 9am (sometimes 8am for events). Some evenings past 8pm for maintenance. On-call for emergencies, sometimes in US hours or at weekends. Paid OT.

Nice to have

• Deeper network skills: firewall policies, SD-WAN, enterprise WiFi, VLANs, RF troubleshooting.
• Apple fleet management; Google Workspace admin.
• A home lab, a GitHub, a blog or anything else that shows you build things.
• ITSM platform admin (Jira Service Management or similar): request types, workflows, SLAs, automation.
• Security-compliance evidence work (SOC 2, ISO 27001).
• Virtualisation and backup tools; physical access-control systems.
• Cloud identity and IAM (any major cloud).
• Vendor and procurement experience.
• Workflow automation tools; AWS basics.
• Networking, security, MDM or Google Workspace certifications.

How to apply

Send your CV with 1-2 short examples of how you used AI in your IT work: the problem, what you did with AI, and the result. A link, a screenshot or a few lines of text is enough. Applications without examples will not move forward.

What success looks like

• 30 days: you have access to every system you own, you know the vendors, and you keep the network and server-room documentation current.
• 90 days: you run the service-desk queue to agreed response times; you own onboarding and offboarding end to end, with evidence; you solve network issues to root cause with data, with a runbook for each.
• 6 months: you own network and server-room changes end to end, vendors and first-line compliance evidence; recurring service-desk and lifecycle work runs largely through automation.
