Network & Wireless Infrastructure Engineer

Christie•Orlando, FL

About The Position

The Global Network & Wireless Infrastructure Engineer designs, implements, administers, maintains, and supports wired and wireless network infrastructure across domestic and international company locations. The position is a hands-on technical role combining network engineering, infrastructure administration, project implementation, and operational support. It is responsible for reliable, secure, high-performing connectivity and consistent network architecture, configuration standards, and security practices across facilities. The role requires substantial enterprise Wi-Fi design, deployment, optimization, and troubleshooting experience, primarily with Ubiquiti UniFi, as well as proficiency with Cisco Catalyst switching and Cisco Meraki MX firewalls. The engineer independently designs and implements moderately complex LAN environments, conducts wireless site surveys and RF assessments, resolves complex network issues, and supports connectivity for business-critical applications and operational devices. Domestic and international travel is required for site assessments, installations, upgrades, troubleshooting, and infrastructure projects. The role may require occasional evenings, weekends, or work outside normal business hours to support planned maintenance, critical incidents, and international operations. This is not an architecture-only or monitoring role; the successful candidate is expected to design, implement, troubleshoot, and administer network infrastructure hands-on.

Strong proficiency with Cisco Catalyst switches and Cisco IOS/IOS XE, including independent configuration and troubleshooting through the command-line interface.
Strong knowledge of VLANs, trunking, STP, LACP, routing, ACLs, and PoE, and ability to design and implement reliable Layer 2 and Layer 3 network architectures.
Hands-on experience administering Cisco Meraki MX firewalls and configuring firewall policies, routing, NAT, VPNs, and WAN connectivity.
Familiarity with Meraki Dashboard monitoring and troubleshooting capabilities.
Strong understanding of TCP/IP, IPv4 subnetting, DNS, DHCP, routing, switching, and network security.
Proficiency using network diagnostic tools, including Wireshark and packet capture utilities.
Ability to independently troubleshoot complex network performance and connectivity problems.
Knowledge of network documentation and infrastructure management best practices.
Ability and willingness to travel domestically and internationally as business needs require.
Ability to obtain and maintain a valid passport and meet applicable international travel requirements.
Ability to work occasional evenings or weekends for planned maintenance, infrastructure implementations, or critical incidents.
Ability to perform on-site network equipment installation and troubleshooting, including work in network closets, equipment rooms, and warehouse environments.
Ability to coordinate projects and technical support across multiple time zones.
Ability to work independently, take ownership of projects, and perform effectively with limited supervision.
Strong analytical, diagnostic, problem-solving, organizational, documentation, time-management, communication, and prioritization skills.
Ability to coordinate technical activities with technical personnel, local management, vendors, service providers, and geographically distributed facilities.
Comfort with both network engineering and routine administration responsibilities, and willingness to support critical infrastructure outside normal business hours when necessary.
An associate's or bachelor's degree in Information Technology, Computer Science, Networking, or a related field is preferred; equivalent professional experience will be considered.
Demonstrated hands-on technical proficiency and relevant experience are more important than formal education or certifications.
