Core Responsibilities

Primary Functions

Perform end-to-end installation of coaxial and fiber-optic cable systems at residential and commercial locations, including running drops, terminating connectors, and installing network interface devices (NID) and customer premises equipment (CPE) to ensure reliable service delivery.
Execute fiber optic fusion splicing and mechanical splicing to industry standards, including proper handling, cleaning, and protection of splices in splice enclosures or handholes to preserve long-term signal integrity.
Conduct optical time-domain reflectometer (OTDR) testing, power meter/laser testing, and loss budgeting on fiber runs to document loss values and verify system performance against SLA expectations.
Install, configure, and troubleshoot cable modems, set-top boxes, routers, ONTs, amplifiers, splitters, taps, and line extenders; validate provisioning and signal levels for data, video, and voice services.
Diagnose and repair signal quality issues using spectrum analyzers, signal level meters, return path monitors, and DOCSIS diagnostic tools to identify ingress/egress, noise, or attenuation sources and apply corrective actions.
Perform outside-plant tasks such as aerial and underground cable placement, pole climbing, truck-mounted boom operations, trenching supervision, and conduit and vault access while following company and industry safety codes.
Route and pull cable through structured pathways, verify proper bend radii for fiber, secure cables and hardware per installation standards, and apply weatherproofing, sealing, and strain relief as required.
Read and interpret network blueprints, site plans, splice maps, and work orders to plan installations and coordinate with other trades and utility locators for safe excavation and overhead work.
Maintain accurate daily work logs, create test reports, update ticketing systems, and document customer interactions, as-built changes, and network modifications for auditing and future troubleshooting.
Respond to service outages, perform emergency repairs, and participate in on-call rotations to restore customer connectivity quickly, escalating complex issues to engineering or NOC as necessary.
Perform preventative maintenance and line conditioning on amplifiers, nodes, taps, and fiber distribution panels to sustain signal quality and reduce repeat service calls.
Install and maintain grounding and bonding systems, surge protection, and power supplies for active network components to protect equipment and minimize downtime from electrical incidents.
Coordinate and communicate with dispatch, project managers, and customers to confirm appointment windows, scope of work, expected disruptions, and completion timelines while maintaining a professional on-site presence.
Follow industry safety regulations (OSHA, NESC), company safety programs, and traffic control protocols while using personal protective equipment (PPE), fall protection, and vehicle safety systems during field work.
Assist with fiber/network build projects including aerial make-ready, pole attachment coordination, conduit pulls, vault installations, and fiber backbone terminations to expand network coverage.
Troubleshoot complex multi-service outages involving coax/fiber handoffs, CMTS or headend issues, and IP provisioning anomalies, working with cross-functional teams to identify root causes.
Perform inventory management for splicing kits, connectors, test equipment, and spare parts; keep company vehicles stocked, organized, and inspected for safe field operations.
Train and mentor junior technicians and apprentices on safe work practices, proper tool use, splicing techniques, testing procedures, and customer service expectations to raise team capabilities.
Perform precise connector terminations for fiber (mechanical/epoxy/ultrasonic) and coax (compression, crimp) ensuring low-loss, reliable connections that meet vendor and company standards.
Execute network upgrades and migrations, including equipment swaps at nodes, CMTS or access devices, and customer premise equipment replacements, ensuring minimal customer impact and accurate cutovers.
Participate in quality assurance audits, follow checklists for critical installs, and remediate any deficiencies found in customer or network inspections to align with SLA and regulatory requirements.
Support coordination with utility companies and third-party contractors for pole attachments, permitting, and right-of-way access to ensure timely and compliant project execution.

Secondary Functions

Provide input into route design and fiber layout recommendations during project planning and pre-construction meetings based on field observations and practical constraints.
Support new product rollouts by providing installation feedback, identifying common failure modes, and suggesting process improvements for repeatable, scalable deployments.
Maintain and calibrate field test equipment, perform routine checks on OTDRs, meters, and fusion splicers, and request vendor service or replacements when necessary.
Participate in cross-functional troubleshooting with network operations, engineering, and provisioning teams to resolve systemic issues and reduce mean time to repair (MTTR).
Assist with inventory tracking and procurement requests for parts and tools, escalating shortages that could affect project timelines.
Contribute to continuous improvement initiatives by documenting installation best practices, job aids, and training materials for new technicians.
Support regulatory and safety compliance inspections by preparing vehicles and documentation, and by implementing corrective actions as directed.
