Recruiters please don't contact this job poster. DO NOT contact us with unsolicited services or offers.

We’re building a small remote IT Operations team in Vietnam to provide helpdesk and operational coverage during weekends and off-peak hours for a globally distributed company. We’re hiring three positions covering:

• Full weekend coverage (Saturday & Sunday, 24 hours) split across three 8-hour shifts
• Weekday shifts (one or two days per person, 06:00–14:00 ICT) covering Asia-Pacific business hours and bridging US/EU gaps

Schedules are coordinated across the team with flexibility to swap shifts as long as full coverage is maintained. Hours range from 24–32 per week depending on schedule.

These are hands-on roles splitting between reactive helpdesk support and proactive project work. During quieter periods you’ll have space for system improvements, maintenance, and new solutions.

Available Schedules (all times ICT/Vietnam)

Schedule A — 32 hours/week

Monday, Friday, Saturday, Sunday: 06:00–14:00

Schedule B — 32 hours/week

Tuesday, Wednesday: 06:00–14:00 | Saturday, Sunday: 14:00–22:00

Schedule C — 24 hours/week

Thursday: 06:00–14:00 | Saturday, Sunday: 22:00–06:00

Please indicate which schedule(s) you’re interested in when applying.

What You’ll Do

• First responder for employee IT support via helpdesk tickets, chat, and other channels.
• Troubleshoot issues across Windows, macOS, and Linux environments.
• Manage user accounts, access, and permissions through Okta, Active Directory, and Google Workspace.
• Administer SaaS platforms including CrowdStrike, Jira, Slack, and others.
• Handle zero-touch workstation deployment and remote endpoint management.
• Monitor systems and security tooling for alerts or events requiring escalation.
• Maintain support documentation and runbooks.
• Coordinate with vendors on hardware procurement, returns, and repairs.
• Take on project work — system improvements, automation, and new solutions during downtime.

• Strong English proficiency, written and verbal. You’ll communicate with employees across multiple timezones via chat, tickets, and video calls.
• Experience in helpdesk, desktop support, or IT operations covering Windows, macOS, and Linux.
• Working familiarity with identity and access management — Okta, Active Directory, or similar.
• Comfort administering cloud-based platforms (Google Workspace, Jira, Slack, etc.).
• Familiarity with Linux servers and/or Windows Server environments.
• Some scripting ability (Bash, Python, or similar) or willingness to develop it.
• Basic understanding of cybersecurity principles — hands-on experience is a plus.
• Personal curiosity about technology — home labs, side projects, automation experiments, anything that shows you tinker and learn on your own.

Bonus

• SSO and provisioning protocols (SAML 2.0, SCIM).
• Endpoint management and zero-touch deployment tools.
• Networking fundamentals, VPNs, and firewall/routing concepts.
• A/V and telecom systems.
• Authorization and privilege management (LDAP/AD binding, least-privilege access).

Work Style
