Senior Network Engineer

SUMMARY

The Senior Network Engineer is a senior technical contributor responsible for advanced network design, implementation, troubleshooting, and escalation support across a diverse client base within a remote MSP environment. This role handles complex network incidents escalated from Tier 1–2, drives proactive improvements, and serves as a subject matter expert in routing, switching, security, and cloud networking. The engineer will work closely with clients and internal teams to deliver high-quality, reliable managed network services.

JOB RESPONSIBILITIES

• Design, configure, and manage enterprise-grade network infrastructure, including routers, switches, firewalls, and wireless systems (Cisco, Palo Alto, Fortinet, Meraki, Juniper, etc.).
• Lead advanced troubleshooting and root cause analysis for complex network issues, including BGP and OSPF routing, inter-VLAN routing, QoS, and WAN performance problems.
• Architect and implement firewall policies, NAT rules, VPN tunnels (IPSec, SSL), and advanced security configurations across multi-vendor environments.
• Manage and optimize SD-WAN deployments, MPLS circuits, and hybrid WAN architectures for MSP clients.
• Administer and troubleshoot cloud networking components in AWS (VPC, Transit Gateway, Direct Connect) and Azure (VNet, ExpressRoute, Azure Firewall).
• Perform in-depth DNS, DHCP, and network services administration and troubleshooting.
• Lead patching, firmware upgrades, and lifecycle management for network appliances across the client base.
• Develop and maintain network monitoring strategies using tools such as LogicMonitor, PRTG, SolarWinds, or equivalent platforms.
• Manage and resolve escalated tickets within MSP platforms (ConnectWise, FreshService, etc.), and document resolutions thoroughly.
• Conduct network assessments and produce architecture diagrams, runbooks, and technical documentation for client environments.
• Conduct periodic network security posture reviews, including vulnerability assessments, configuration audits, and hardening recommendations aligned with NIST, CIS, or client-specific frameworks.
• Evaluate emerging network technologies, vendor platforms, and tooling on behalf of the MSP, and provide recommendations for adoption into the standard service stack.
• Support pre-sales and scoping efforts by participating in client discovery calls, reviewing SOWs, and contributing to network design proposals and SOW development.

SUPPORT AND OPERATIONS

• Serve as the primary escalation point for network incidents and own resolution from escalation through closure.
• Lead change management activities, including planning, scheduling, implementing, and validating production network changes.
• Participate in on-call rotation and after-hours maintenance windows as required.
• Collaborate with ISPs, hardware vendors, and cloud providers to coordinate circuit provisioning, RMAs, and complex issue resolution.
• Assist in onboarding new MSP clients, including network discovery, documentation, and transition planning.
• Identify recurring issues and drive proactive improvements to reduce incident volume and improve client stability.

SOFT SKILLS AND PROFESSIONALISM

• Excellent verbal and written communication skills required for client-facing interactions and technical documentation.
• Ability to convey complex technical concepts to non-technical stakeholders clearly and professionally.
• Strong time management skills, with the ability to handle multiple client priorities simultaneously in a fast-paced remote MSP environment.
• Collaborative mindset with a commitment to mentoring Tier 1–2 engineers and contributing to team knowledge sharing.
• Self-directed and accountable, with the ability to work independently in a fully remote setting with minimal supervision.

QUALIFICATIONS

• Five to seven or more years of hands-on network engineering experience, preferably in an MSP or multi-client managed services environment.
• Deep expertise with at least two major network vendors (e.g., Cisco, Palo Alto, Fortinet, Meraki, Juniper).
• Experience with network automation and scripting using Python, Ansible, PowerShell, or similar tools.
• Familiarity with compliance frameworks (HIPAA, SOC 2, NIST, PCI-DSS) as they apply to network security controls.
• Exposure to ITSM and ITIL practices within a managed services delivery model.
• A degree in Information Technology, Computer Science, Network Engineering, or equivalent experience.
• Required or highly preferred certifications include Cisco CCNP (Enterprise or Security), Palo Alto PCNSE, Fortinet NSE 5–7, or equivalent advanced vendor certifications.
• Additional desirable certifications include AWS Certified Advanced Networking, Microsoft Azure Network Engineer Associate, and CompTIA Network+ or Security+.

JOB REQUIREMENTS

• Should be willing to accept a long-term work-from-home arrangement.
• Should be amenable to a permanent 24/7 shift schedule.
