About the role

We're looking for a Network and Security Administrator to own our day-to-day network infrastructure while also managing device security, access control, and security awareness programs across the company. This role is primarily focused on building and maintaining a reliable, well-documented network, with security as a close second responsibility. You'll work directly with the IT Manager on architecture decisions as Ohalo adds new sites, equipment, and integrations.

• 5+ years of experience in network administration, IT infrastructure, or a closely related role
• Hands-on experience with the Ubiquiti UniFi ecosystem (UniFi Network, Access, Protect) or comparable enterprise networking hardware
• Solid understanding of WAN technologies, wireless/wired networking, and core networking protocols (TCP/IP, DHCP, DNS, VLAN, VPN)
• Experience administering MDM/UEM platforms (Hexnode or similar) and Google Workspace
• Comfortable creating and maintaining SOPs, IT policies, and process documentation
• Experience with workflow automation, and interest in applying AI tools to streamline IT operations
• Familiarity with Notion, Jira, and Slack for documentation and team collaboration
• Working knowledge of security fundamentals — access controls, security awareness training (e.g., KnowBe4), and basic network hardening
• Strong troubleshooting skills and comfort working independently in a lean IT environment
• Clear communicator who can support non-technical staff across lab, field, and office environments
• Experience supporting hybrid environments that span office, lab, and field/remote sites
• Networking or security certifications (Network+, CCNA, Security+, or similar)
