Core Responsibilities

Primary Functions

Conduct detailed on-site pre-installation surveys, measure mounting locations, evaluate electrical panels, attic and roof access, and document potential code or structural issues prior to installation.
Install, wire and ground residential systems including photovoltaic arrays, battery storage systems, inverters, AC/DC disconnects, conduit, and associated electrical components in compliance with NEC and local jurisdiction requirements.
Mount and terminate low-voltage and network cabling (Cat5e/Cat6/Coax), perform RJ45/RG6 terminations and test connectivity using cable testers and certification tools to guarantee signal integrity.
Perform fiber optic drops, splice and terminate fiber ends, and verify light levels and loss using OTDRs and power meters for residential fiber-to-the-home (FTTH) installations.
Install and configure residential routers, switches, Wi-Fi access points, mesh systems, set-top boxes, and smart-home hubs; verify internet connectivity, signal strength, and QoS parameters.
Mount and configure security and surveillance hardware: cameras, door/window sensors, motion detectors, control panels, and alarm communicators; test detection zones and tamper circuits.
Precisely layout and install HVAC mini-split systems and ductless units, run refrigerant lines, evacuate systems and perform leak checks and pressure tests as required by manufacturer specifications.
Read and interpret blueprints, site plans and wiring diagrams; translate plans into accurate hardware placement and electrical connections during installation.
Use hand and power tools (drills, saws, crimpers, multimeters, torque wrenches, conduit benders) safely and maintain tool inventory and calibration.
Complete in-field programming and firmware updates for devices, validate firmware compatibility, and ensure all devices are on supported software versions.
Perform system commissioning and quality assurance checks: run functional tests, calibrate sensors, validate energy production (for solar), and perform thermal or signal diagnostics as needed.
Troubleshoot complex installation issues—electrical faults, network packet loss, signal degradation, inverter alarms—using structured diagnostics and escalate to engineering when required.
Ensure job site safety and compliance: perform lockout/tagout, follow ladder and fall protection protocols, wear required PPE, and adhere to OSHA and company safety policies.
Maintain clear, professional communication with homeowners: explain system operation, demonstrate user interfaces, walk-through warranty and service expectations, and obtain customer sign-off.
Accurately document time on site, parts used, change orders, and as-built wiring diagrams in the company’s CRM/field service management system before leaving the job site.
Coordinate scheduling and logistics with dispatch and project managers to ensure on-time arrivals, proper permit status, and material availability for same-day installs or follow-up.
Assemble and test backup power solutions and transfer switches, confirm safe isolation from the grid where applicable, and validate automatic transfer functionality in generator or battery systems.
Perform post-install inspection and punch-list remediation: correct loose connections, replace damaged components, and retest to ensure long-term reliability.
Train and mentor junior technicians and apprentices in installation best practices, safety procedures, tool use, and customer interaction techniques.
Follow manufacturer installation manuals and warranty requirements to preserve customer warranties and reduce future service calls.
Respond to emergency service requests for outages, safety hazards, or failed equipment, applying diagnostic triage and repair techniques to restore service quickly and safely.
Maintain a clean, organized vehicle stock of parts, materials, and tools; perform basic vehicle maintenance checks relevant to job readiness.
Participate in regular team safety meetings, continuous improvement initiatives, and provide feedback on installation processes to reduce rework and increase first-time-right rates.
Implement quality control measures on-site: torque electrical connections to spec, apply appropriate sealants and weatherproofing, and ensure all penetrations are fire- and pest-resistant where applicable.

Secondary Functions

Support ad-hoc technical escalations from dispatch and coordinate with remote engineering support to resolve complex field issues.
Assist in inventory audits and parts reconciliation; flag recurring parts shortages and recommend stock adjustments to procurement.
Contribute to installation SOPs and job aids by documenting common field fixes, installation shortcuts, and safety observations.
Participate in pilot rollouts for new products and tools; provide hands-on feedback to product teams about installer experience and real-world constraints.
Complete required compliance paperwork, permit submittals, and inspection coordination with local building departments when requested.
Provide occasional pre-sales technical support during site surveys or customer consultations to scope installations and propose optimal system designs.
Evaluate and recommend upgrades to tools and testing equipment to improve test accuracy and reduce time on site.
Enter detailed job notes and condition reports in CRM to support billing, warranty claims, and customer support handoffs.
Support company sustainability goals by properly disposing of old equipment and recycling materials according to local regulations.
Attend periodic training and certification renewals (e.g., OSHA, NFPA70E, manufacturer certification) and maintain up-to-date credentials.
