全职 System Engineer 工作, 薪水 up to SGD 3,500, AKRIBIS SYSTEMS PTE. LTD. North-east Region (Singapore) 公司招聘中 - Ricebowl

This role combines systems administration, scripting, and process improvement to reduce manual work, improve reliability, and support day-to-day IT operations. Working closely with the Site Reliability Engineer, you will help maintain core systems, drive meaningful automation, and contribute to a more efficient and stable IT environment for our engineering teams.

Roles & Responsibilities:

1. 1Own LAN and site connectivity, including switching, VLAN design, inter-VLAN routing, wireless, firewall policy, site-to-site VPN (including China links), and network segmentation. Maintain accurate topology records and ensure changes are documented and reversible.
2. Administer core infrastructure, including Windows and Linux servers, virtualization (Proxmox/PVE or equivalent), storage, backup and restore, and Microsoft Entra ID / Microsoft 365 identity and access management.
3. Own endpoint and workstation operations for engineering systems, including CAD/SolidWorks-class PCs: imaging, drivers, patching, endpoint security, and asset hygiene. Provide Level 2 support for floor incidents and resolve issues across network, identity, and endpoint layers.
4. Apply operational security controls, including patching, system hardening, least-privilege access, logging and alerting, and periodic access reviews. Security is treated as part of day-to-day operations rather than a separate function.
5. Manage vendor engagement for circuits, hardware, and warranty support, remaining accountable for service outcomes and delivery quality.
6. Automate repeatable operational work using PowerShell, and Microsoft Power Automate where it is the appropriate tool. All automations must include access control, error handling, auditability, and a defined rollback path.
7. Execute user lifecycle operations, including onboarding, offboarding, access provisioning, and ad-hoc operational support for engineering teams.
8. Produce and maintain operational documentation suitable for handover and incident response, including network diagrams, runbooks, change records, and restore procedures.
9. Track operational performance (incident rate, restore time, provisioning time, patch compliance) and propose improvements. Escalate risk to the Site Reliability Engineer with clear impact and recommended action.

Requirements

1. Demonstrated hands-on experience operating enterprise or mid-size LAN environments, including VLAN design, switching, firewall policy, VPN, and wireless. Documentation-only network experience is insufficient.
2. Systems administration experience covering Windows Server and Linux, plus virtualization (Proxmox/PVE, or equivalent).
3. Practical identity and access administration in Microsoft Entra ID / Microsoft 365, or Active Directory integrated with Entra, including group management and joiner/mover/leaver processes.
4. Endpoint and workstation support experience, including engineering or CAD-class PCs, imaging, peripheral support, and troubleshooting of connectivity and license-server access issues.
5. Proven backup and restore experience, and applied operational security practices (patching, hardening, access restriction, and logging).
6. Ability to work independently in a small team, document changes, and take operational issues from physical connectivity through identity and endpoint resolution.

Nice to have:

• Microsoft Intune
• Asset management platforms
• Production PowerShell
• Dual-site or China/APAC VPN operations
• Bilingual English and Mandarin
• A diploma or degree in IT or a related field is preferred but not required where equivalent hands-on experience is demonstrated.
