Network Security Engineer

A growing US-based hosting and managed services provider is seeking a Senior Network / Security Engineer to support multi–data center operations across the United States.

This is a hands-on role within a fast-paced hosting environment. The ideal candidate brings strong networking expertise, solid Linux fundamentals, and deep experience in virtualization, particularly KVM-based environments.

If you thrive in an infrastructure-heavy environment where systems are continuously evolving, and automation is key, this opportunity offers meaningful technical depth and impact.

Responsibilities

• Manage and maintain network infrastructure across multiple U.S. data centers
• Configure and support routing and switching environments (Fortinet, Cisco, Dell)
• Design and maintain resilient L2/L3 network segments (BGP, OSPF, VRRP, STP, SD-WAN)
• Implement and manage firewall policies, IDS/IPS, and VPN configurations
• Support and administer Linux and Windows server environments
• Manage and troubleshoot KVM-based virtualization (OpenNebula experience preferred)
• Participate in ongoing infrastructure upgrades, firmware updates, and system enhancements
• Contribute to automation initiatives using scripting (Bash, Python, etc.)
• Support cloud networking environments (AWS, Azure, or GCP)

Required Experience

• Ideally, a background in hosting or MSP environments, but not required.
• Advanced knowledge of routing protocols (BGP, OSPF) and multi–data center networking
• Hands-on Linux systems administration experience
• Experience with KVM virtualization (VMware/Hyper-V familiarity helpful)
• Experience supporting high-availability, resilient infrastructure
• Ability to work independently while collaborating within a technical team
• Team-oriented and collaborative
• Comfortable in fast-moving environments with continuous upgrades
• Curious, adaptable, and eager to learn
• Senior enough to operate autonomously, yet still hands-on day-to-day

This opportunity is ideal for engineers who enjoy solving complex infrastructure challenges within a hosting/MSP model and want to contribute to a growing organization.
