New Job Opening: Network Security Engineer in New York City

Network Security Engineer — Check Point / Fortinet / F5

New York City / Jersey City | Hybrid | $125k–$160k + Benefits (including health insurance)

Neos Talent is supporting a live requirement for a hands-on Network Security Engineer to join a major financial services environment in the NYC / Jersey City area.

This is a practical, production-focused role supporting critical network security infrastructure. It is best suited to someone who enjoys being close to the technology, solving live issues, managing controlled changes and supporting a highly regulated enterprise environment.

This is not a general network support role and it is not a high-level architecture position. The key requirement is recent hands-on depth across firewall, proxy, DNS and load-balancing technologies.

Role overview:

• Salary: $125k–$160k base


• Location: NYC / Jersey City area


• Working pattern: Hybrid — typically 3 days per week onsite 


• Benefits: Healthcare, benefits package and flexible working


• Environment: Major financial services / banking infrastructure


• Role type: Hands-on BAU / L3-L4 Network Security Engineering

Essential experience:

• Strong hands-on experience with Check Point and Fortinet / FortiGate


• Firewall policy changes, NAT, VPNs, rule reviews, upgrades and troubleshooting


• Operational experience with F5 LTM / GTM


• DNS / DHCP support, ideally using Infoblox


• Proxy experience, ideally Blue Coat and/or McAfee


• L3/L4 production support experience, including incidents, change windows, RCA and documentation


• Strong troubleshooting across TCP/IP, routing, firewalls, proxies, DNS and application connectivity


• Comfortable working in a structured financial services / enterprise environment

Financial services or banking experience would be useful, but the priority is hands-on operational depth across the core security technologies.
