IT Infrastructure, Security & Operation

What You'll Do

• Analyze business and user requirements and translate them into infrastructure and network solutions, taking into account capacity, availability, and security needs.
• Design, configure, and maintain network infrastructure (LAN, WAN, Wi-Fi, VPN, switches, routers, firewalls) across head office, plant, warehouse, and branch sites to ensure connectivity and operational reliability.
• Provide L2/L3 support for infrastructure and network incidents, including troubleshooting and root cause analysis, in coordination with IT helpdesk, internet service providers (ISPs), and external vendors.
• Collaborate with cross-functional teams (Finance, Supply Chain, Manufacturing, Sales, HR) to ensure infrastructure and network services support business applications (including ERP/SAP connectivity) and operational needs.
• Coordinate with vendors, ISPs, and system integrators for procurement, implementation, integration, and managed services, and monitor vendor SLA performance.
• Administer and maintain servers, virtualization, storage, backup, and cloud environments (e.g., Windows/Linux Server, Proxmox, Active Directory, Microsoft 365, Azure Cloud, Azure Databases) to ensure availability and performance.
• Implement and monitor IT security controls (firewall policy, access management, patching, endpoint protection, vulnerability remediation) and ensure compliance with internal IT policies and audit requirements.
• Plan and execute infrastructure upgrades, firmware/patch updates, migrations, and disaster recovery drills, including testing, cutover, and handover to users and support teams.
• Prepare and update technical documentation, including network topology diagrams, IP addressing plans, configuration baselines, SOPs, and DR/BCP documents.
• Manage and maintain CI/CD tools and container orchestration platforms (e.g., GitLab, Docker, and Kubernetes) and integrate Static Application Security Testing (SAST) into development pipelines to improve deployment reliability and application security.
• Monitor infrastructure and network performance using monitoring tools, conduct capacity planning, and recommend improvements or automation opportunities.

What You Bring

• Minimum 3 years of experience in IT infrastructure and network administration, support, or implementation.
• Bachelor’s degree in Information Technology, Information Systems, Computer Science, Telecommunications/Electrical Engineering, or related field.
• Involvement in network, server, or infrastructure deployment, upgrade, or migration projects.
• Exposure to full-cycle infrastructure project implementation (design, deployment, testing, and handover).
• Familiarity with network monitoring and ITSM tools (e.g., Zabbix, PRTG, SolarWinds, ServiceNow). Relevant certifications such as CCNA/CCNP, Fortinet NSE, VMware VCP, Microsoft Azure, or ITIL are an advantage
