About The Position

Greenberg Traurig is hiring a Network Engineer with a focus on load balancing for its Technology Team. The role can be based in various offices on a hybrid basis and reports to the Director of Network Systems. It is responsible for installing, operating, maintaining, and troubleshooting enterprise application-delivery and network services for a large, multinational organization, primarily supporting network load balancing. The engineer will support Citrix NetScaler and Kemp LoadMaster platforms, or comparable load-balancing technologies, and maintain working knowledge of LAN, WAN, firewall, Wi-Fi, cloud, and network automation technologies. The position designs, implements, administers, and supports load-balancing and application-delivery infrastructure; configures virtual servers, services, pools, health monitors, persistence, content switching, traffic policies, redirects, and SSL/TLS offload; and administers high-availability pairs and clusters. It also addresses application-delivery issues across network and application layers, partners with application, security, cloud, and infrastructure teams, maintains secure certificate and protocol configurations, and develops operational documentation. Monitoring, capacity analysis, performance reporting, automation, and support for enterprise network and hybrid-cloud connectivity are also part of the role. Occasional travel is required.

Ability to analyze end-to-end application traffic flows across DNS, load balancers, firewalls, servers, proxies, and cloud services.
Very strong knowledge of TCP/IP, HTTP/HTTPS, DNS, routing, NAT, SSL/TLS, and network traffic analysis using tools such as Wireshark.
Knowledge of certificate formats, certificate chains, cipher suites, TLS versions, and certificate renewal and replacement processes.
Experience with load-balancer monitoring, logging, performance analysis, capacity planning, configuration backup, and disaster recovery.
Working knowledge of enterprise routing, switching, firewall, VPN, and Wi-Fi technologies.
Working knowledge of dynamic routing protocols and data-center networking concepts, including OSPF, BGP, VXLAN, BGP-EVPN, and DCI.
Working knowledge of cloud networking in Microsoft Azure and/or AWS, including hybrid connectivity, security policies, and cloud-native monitoring.
Understanding of Zero Trust Network Architecture principles as applied to application delivery and hybrid-cloud environments.

Responsibilities

Design, implement, administer, and support enterprise load-balancing and application-delivery infrastructure, with a preference for Citrix NetScaler and Kemp LoadMaster; comparable platforms such as F5 BIG-IP are acceptable.
Configure and troubleshoot virtual servers, services, service groups, pools, health monitors, persistence methods, content switching, traffic policies, redirects, and SSL/TLS offload.
Administer high-availability load-balancer pairs and clusters, including synchronization, failover testing, software upgrades, backup, recovery, and lifecycle management.
Troubleshoot application-delivery issues across network and application layers using packet captures, platform logs, health checks, and traffic-flow analysis.
Partner with application, security, cloud, and infrastructure teams to onboard applications, define load-balancing requirements, validate dependencies, and support production changes.
Maintain certificates, cipher settings, protocol policies, and secure application-delivery configurations in coordination with security standards and certificate-management processes.
Develop and maintain standards, diagrams, runbooks, inventories, and implementation documentation for load-balancing services.
Implement monitoring, alerting, capacity analysis, and performance reporting for load balancers and related application-delivery services.
Automate repeatable network and load-balancer administration using PowerShell, Python, Ansible, REST APIs, or other approved tools.
Support enterprise routing, switching, WAN, firewall/DMZ, Wi-Fi, VPN, and hybrid-cloud connectivity as secondary areas of responsibility.
Support hybrid-cloud network connectivity to Microsoft Azure and/or AWS, including related routing, security, and application-delivery integration.
Travel occasionally.
