About the role

ResiBridge is seeking a motivated Junior Network Engineer to support the operation, deployment, and continued growth of our ISP network. Working directly with the CTO and senior engineering staff, this individual will assist with network monitoring, incident response, equipment provisioning, documentation, field coordination, infrastructure deployments, and ongoing network maintenance.

This position is designed for someone with strong networking fundamentals, hands‑on technical ability, and a desire to grow into a well‑rounded ISP network engineer. Candidates are not expected to arrive with expertise in every technology we operate. ResiBridge will provide hands‑on training in areas including MikroTik routing and switching, fiber‑optic networks, GPON and XGS‑PON systems, carrier‑grade wireless equipment, monitoring platforms, network automation, and ISP operations.

The role combines network operations and engineering work with occasional field deployments throughout New York City and the surrounding metropolitan area. Approximately 20% travel or field work may be required.

Responsibilities

Network Operations and Troubleshooting

• Monitor network health, availability, capacity, and performance using platforms such as Grafana, Prometheus, and vendor management systems.
• Investigate network alerts, customer impacting incidents, equipment outages, and performance issues.
• Perform initial troubleshooting of routers, switches, wireless systems, OLTs, ONTs, and related network infrastructure.
• Gather relevant logs, configurations, monitoring data, packet captures, and field information before escalating complex issues.
• Assist with diagnosing DHCP, DNS, VLAN, routing, switching, NAT, wireless, and general connectivity problems.
• Participate in planned network maintenance, upgrades, configuration changes, and service migrations.
• Follow established escalation, change‑control, and incident‑response procedures.

Network Configuration and Provisioning

• Provision and configure routers, switches, access points, OLTs, wireless bridges, and other network equipment.
• Assist with MikroTik RouterOS configuration, validation, backups, upgrades, and troubleshooting.
• Review device configurations for accuracy and consistency before deployment.
• Maintain addressing plans, VLAN assignments, equipment records, configuration standards, and network documentation.
• Assist with testing new equipment, software versions, configurations, and network designs before production deployment.

Fiber and Wireless Infrastructure

• Support the installation, testing, maintenance, and troubleshooting of fiber‑optic and high‑capacity wireless networks.
• Assist with the deployment and operation of GPON and XGS‑PON infrastructure, including OLTs, ONTs, splitters, and optical distribution systems.
• Perform or assist with fiber continuity testing, optical power measurements, connector inspection, cleaning, and basic fault isolation.
• Support point‑to‑point and point‑to‑multipoint wireless systems operating in the 5 GHz, 24 GHz, 60 GHz, and 70/80 GHz frequency bands.
• Assist with wireless alignment, signal verification, interference analysis, capacity review, and link‑performance optimization.
• Review field surveys, installation photos, path information, equipment locations, and closeout documentation.

Field and Vendor Coordination

• Perform occasional on‑site installations, equipment replacements, maintenance, testing, and troubleshooting.
• Coordinate with field technicians, contractors, property staff, vendors, and service providers.
• Confirm that field work has been completed according to the approved design and documentation.
• Identify missing information, workmanship concerns, safety issues, or installation deficiencies and clearly document required corrections.
• Assist with structured cabling, equipment mounting, labeling, and network hardware installation when needed.

Systems, Documentation and Automation

• Perform basic Linux system administration and troubleshooting.
• Assist with the operation of Docker‑based applications and internal engineering tools.
• Create and maintain clear documentation for network configurations, troubleshooting procedures, deployments, and incident responses.
• Maintain accurate records in systems such as NetBox, inventory platforms, configuration repositories, and ticketing systems.
• Assist with Python, Bash, API, or other automation projects that improve reliability and reduce repetitive manual work.
• Help develop repeatable procedures, checklists, and internal standards as the network and engineering team grow.
