Job Description

Position Summary

Client is seeking a Network Engineer to help design, implement, and support secure, reliable network services across our on-premises and cloud environments. In this role you will work with infrastructure, security, and application teams to deliver network changes, maintain network health, and troubleshoot issues affecting performance and availability. You will contribute to standards, documentation, and continuous improvement while ensuring solutions align with business and security requirements.

Key Responsibilities

Network Operations & Support

• Monitor network performance and availability; respond to incidents and service requests in line with SLAs.
• Troubleshoot and resolve LAN/WAN/Wi-Fi connectivity issues, routing/switching faults, and VPN problems.
• Perform routine maintenance, patching, and upgrades of network devices and services.
• Maintain accurate documentation including diagrams, configurations, runbooks, and change records.
• Work with vendors and service providers to diagnose and remediate circuit or hardware issues.

Implementation & Change Delivery

• Implement network changes (adds/moves/changes, VLANs, ACLs, NAT, VPNs) following change control and security standards.
• Assist with network design and build activities for office sites, data center connectivity, wireless, and hybrid cloud.
• Configure and support common routing and switching technologies (e.g., OSPF/BGP, STP, QoS, port security).
• Support integration of network infrastructure with servers, storage, virtualization platforms, and cloud services.
• Participate in project delivery by estimating effort, contributing to technical designs, and validating implementations.

Security & Compliance

• Apply security controls such as segmentation, least-privilege access (ACLs), VPN encryption, and secure management access.
• Assist with firewall rule requests and network access changes in partnership with security teams.
• Support vulnerability remediation activities and help ensure network configurations meet internal standards and audit requirements.
• Contribute to continuous improvement by identifying recurring issues and recommending practical fixes.

Skills & Knowledge

• Hands-on experience with routing and switching fundamentals: IPv4/IPv6, VLANs, STP, OSPF and/or BGP, NAT, QoS.
• Experience supporting network services such as DNS, DHCP, and IP address management (IPAM).
• Working knowledge of network security concepts: segmentation, VPNs, firewalling basics, and secure administration.
• Familiarity with wireless networking (802.11), authentication, and troubleshooting.
• Experience with monitoring and troubleshooting tools (e.g., logs, packet captures, SNMP/telemetry dashboards).
• Comfort working in ITSM processes (incident/problem/change) and documenting solutions.
• Scripting/automation exposure (e.g., PowerShell, Python, APIs) is a plus.

Qualifications

• Bachelor’s degree in Information Technology, Computer Science, or equivalent practical experience.
• 3-5 + years of hands-on experience supporting and implementing network infrastructure in an enterprise environment.
• Experience configuring and supporting routers, switches, and firewalls in production.
• Ability to communicate clearly with technical and non-technical stakeholders and work effectively across teams.
• Strong problem-solving skills, attention to detail, and a customer-service mindset.

Nice to Have

• Exposure to cloud networking (e.g., Azure/AWS networking constructs, VPN/ExpressRoute/Direct Connect).
• Experience with network access control (NAC) and enterprise Wi-Fi platforms.
• Familiarity with SD-WAN technologies and/or SASE concepts.
• Relevant certifications (e.g., CCNA, Network+, vendor firewall certifications).
