Overview

The Site Readiness Technician III is a master technician and field supervisor responsible for leading inspection crews and driving Site Readiness execution on ON.energy’s mission-critical, medium-voltage double-conversion UPS systems built on utility-scale BESS equipment (batteries, transformers, PCS, and controls). The Technician III performs advanced receiving and mechanical completion inspections, leads non‑conformance disposition, supports pre‑energization readiness, and mentors junior technicians while maintaining the highest standards of safety and quality.

This is a senior, hands‑on, high‑travel field role for a technician who can operate autonomously, supervise crews, and interface directly with the Site Readiness Manager, commissioning engineers, EPC partners, and OEM representatives.

Key Responsibilities

Safety Leadership

• Foster and maintain a culture of safety for all team members, overseeing JHA and LOTO program compliance and maintaining zero recordable injuries.

Field Supervision

• Act as field supervisor for teams of 2–12 Site Readiness Technicians.
• Work autonomously to further project readiness goals and maintain inspection quality and tracking standards with junior members.
• Provide hands‑on training to junior and intermediate technicians on inspection procedures, documentation, and acceptance criteria.
• Perform advanced receiving inspections and mechanical completion verification on BESS containers, battery racks/modules, inverters, transformers, switch gear, telecom cabinets, and auxiliary systems.
• Verify torque, terminations, grounding, cable routing, labeling, conduit, and enclosure integrity against approved submittals, drawings, OEM requirements, and the project Quality Plan.
• Lead initial disposition of non‑conformances; initiate and track NCRs and punch list items through closure, escalating to the Site Readiness Manager and engineering when issues cannot be resolved in the field.
• Support pre‑energization readiness reviews and quality walkdowns with commissioning.

OEM/EPC Interface & Documentation

• Interface with OEM field representatives and EPC quality personnel; relay findings to the Site Readiness Manager and engineering.
• Maintain excellent documentation habits — inspection reports, photographic evidence, redlines, and field discrepancy tracking — in the project platform (Overmap, CxAlloy, or equivalent).
• Proficient in the safe use of standard hand tools and calibrated torque tools for verification of assembly and installation.
• Skilled in operating inspection and diagnostic equipment including digital multimeters, clamp meters, insulation resistance testers, and other measurement devices commonly used in battery energy storage systems.

Required Qualifications

• 5+ years hands‑on experience in field inspection, construction QA/QC, or electrical/mechanical commissioning on power systems.
• Working knowledge of NEC, NFPA 70E, IEEE, UL 9540/9540A, utility standards, and OEM installation requirements.
• Associate degree or vocational/military training in Electrical, Electronics, or a related technical field.
• Strong judgment on dispositioning defects and knowing when to escape to engineering.
• Willing and able to travel up to ~80%…
