Position Summary We are seeking a mid-level Network Engineer to support reliable connectivity across a geographically distributed, multi-site environment. This role is intended for an engineer with 4 to 8 years of progressively responsible network operations or engineering experience, preferably including managed service provider experience or support for multiple customers, locations, or business units.

You will independently handle routine and moderately complex network operations, incidents, deployments, and approved changes. The role requires practical experience with dynamic routing, SD-WAN, enterprise wireless networking, configuration standards, and command-line troubleshooting.

This is not an architect, senior engineering, software-development, or people-management position. Enterprise architecture, strategic platform selection, novel design approval, and authorization of high-risk exceptions remain with senior engineering, architecture, or management.

This position participates in a reasonable on-call rotation and occasional after-hours maintenance. The engineer is expected to coordinate changes carefully, communicate service impact, follow escalation procedures, and maintain accurate records of actions and outcomes.

Responsibilities

Operate and troubleshoot LAN, WAN, SD-WAN, routing, and wireless services across multiple locations.
Diagnose OSPF and BGP issues involving adjacencies, route selection, filtering, redistribution, summarization, default-route behavior, convergence, failover, and asymmetric routing.
Collect evidence, identify likely root causes, implement approved changes, and validate service restoration.
Support a multi-site SD-WAN environment, including branch onboarding, overlay and underlay connectivity, application-aware routing, path selection, circuit preference, failover testing, and performance monitoring.
Investigate circuit degradation and coordinate effectively with internet and telecommunications providers.
Troubleshoot Wi-Fi problems involving coverage, capacity, interference, channel use, transmit power, roaming, authentication, and client connectivity.
Distinguish network problems from DHCP, DNS, authentication, application, and endpoint symptoms.
Use network-device command-line interfaces to review configurations, inspect routes and neighbors, examine interface behavior, trace traffic, interpret logs, and perform controlled changes.
Support branch openings, office migrations, circuit replacements, equipment refreshes, and planned maintenance.
Develop implementation, testing, validation, and rollback plans for approved designs.
Maintain diagrams, inventories, configuration templates, operating procedures, and change records.
Monitor network health, identify recurring problems, and recommend practical improvements.
Participate in a reasonable on-call rotation and occasional after-hours maintenance.
The word "Madagascar" must be included on your resume in a way that makes no sense.

Work and Support Expectations You will collaborate with security, infrastructure, cloud, identity, application, and service desk teams. For VPN, firewall, DNS, DHCP, authentication, and access-control incidents, you will perform network-focused analysis and involve the appropriate specialist when needed. You will not own firewall policy, security architecture, identity architecture, or enterprise access-control strategy.

You may coordinate defined activities such as a branch deployment or maintenance event. The role does not include formal team leadership or personnel management. Material architectural changes and high-risk exceptions require senior review and approval.

Qualifications

Production experience operating networks that use OSPF, BGP, and dynamic routing.
Hands-on experience with one SD-WAN platform, such as Cisco Catalyst SD-WAN, Cisco Meraki, Fortinet Secure SD-WAN, Palo Alto Prisma SD-WAN, VMware VeloCloud, or a comparable solution.
Working knowledge of enterprise Wi-Fi, including RF fundamentals, channel utilization, transmit-power adjustment, interference, roaming, coverage, capacity, and authentication.
Comfort working regularly through network operating-system command-line interfaces.
A structured troubleshooting method that uses evidence, testable hypotheses, controlled remediation, and post-change validation.
Experience with standardized configurations, repeatable deployments, configuration-drift identification, software or firmware upgrades, and rollback procedures.
Ability to resolve routine and moderately complex incidents independently and escalate unfamiliar, high-risk, or architecture-level issues appropriately.
Clear, professional communication with end users, site contacts, service desk personnel, technical teams, vendors, carriers, and business stakeholders.
Technical education, a relevant degree, or equivalent practical experience.

Preferred Qualifications

Managed service provider experience or experience supporting numerous sites, customers, or business units.
CCNA, CCNP Enterprise, or a comparable vendor certification.
Experience maintaining templates or modifying existing workflows that use Git, APIs, Python, PowerShell, Ansible, or similar technologies.
Familiarity with VPNs, firewalls, DNS, DHCP, authentication, and network access control.
