Full Time Solutions Engineer Jobs, in One Net Group - Maukerja

Location: Singapore

About the Role

We're a maritime-focused Managed Service Provider delivering IT infrastructure and support across a fleet of approximately 5000 vessels. We're looking for a Solutions Engineer to join our technical team, working hands-on across virtualization, networking, Windows/Linux server administration, and telephony systems that keep vessels connected and operational worldwide.

This is a senior individual-contributor role with real ownership — you'll be managing production infrastructure that vessel crews and shore-side operations depend on daily, often under satellite-connectivity constraints that make this work meaningfully different from standard corporate IT.

What You'll Do

• Manage Windows Server / Active Directory environments including GPO, DNS, and user/role provisioning
• Administer AlmaLinux/RHEL systems supporting core vessel and shore infrastructure
• Administer and troubleshoot KVM/libvirt virtualization across vessel and shore-based host clusters
• Use NinjaRMM and ScreenConnect for remote monitoring, patch management, and remote support across the fleet
• Configure and maintain WatchGuard firewalls and network security across the fleet
• Support 3CX/SIP telephony infrastructure, including PBX provisioning and troubleshooting
• Write and maintain Ansible / PowerShell automation for fleet-wide provisioning and configuration management
• Troubleshoot connectivity and infrastructure issues across satellite (VSAT/Starlink), LTE, and hybrid WAN links
• Coordinate with vessel crews, shore-side operations, and vendors to resolve incidents within SLA
• Contribute to documentation, SOPs, and knowledge-sharing across the technical team
• Support pre-sales / proposal work where technical input is needed for new fleet onboarding or RFQs

What We're Looking For

Required:

• 5+ years of hands-on experience in IT infrastructure, networking, or systems engineering
• Networking fundamentals: routing, VLANs, firewall administration (any enterprise-grade vendor — Palo Alto, Fortinet, Cisco, WatchGuard, etc.), and VPN technologies (SSL VPN, IPsec, site-to-site)
• Experience with Windows Server and Active Directory administration (GPO, DNS, DHCP, OU structure)
• Solid working knowledge of Linux server administration (RHEL/AlmaLinux/CentOS or similar)
• Practical experience with virtualization (KVM/libvirt, VMware, Hyper-V, or Proxmox)
• Strong troubleshooting instincts and comfort working independently under time pressure

Highly Valued (nice-to-have):

• Familiarity with NinjaRMM, ScreenConnect, or comparable RMM/remote-support tooling
• Experience with 3CX or other SIP/VoIP PBX systems
• Ansible or other configuration-management/automation experience
• PowerShell scripting for Windows administration and automation
• Working knowledge of AWS (or other cloud platforms) for hybrid infrastructure or backup use cases
• Experience supporting remote or satellite-connected sites (maritime, oil & gas, remote mining, etc.)
• Exposure to maritime IT, VSAT/satellite communications, or fleet-scale multi-site management
• Relevant certifications (CCNA/CCNP, Fortinet NSE, VMware VCP, RHCSA, or similar)
