Senior Field Service Technician EV Charging Tier III

Zero Impact Builders • Menlo Park, CA

23d • $75,000 - $85,000 • Onsite

About The Position

ChargeTronix is hiring a senior Tier III field service technician to serve as the top technical escalation point on its service team. The role focuses on the company's modular DC fast chargers and is responsible for territory uptime, complex troubleshooting and component-level repairs, commissioning new installations, mentoring Tier I and Tier II technicians, and feeding structured failure data to engineering. The technician works independently with little supervision and makes on-site safety and repair decisions. The position is based in Southern California and requires travel of 75% or more, including multi-day regional vehicle trips and periodic out-of-state air travel; the technician is home most weekends. The role reports to the Field Service Manager and has no direct reports, while serving as a technical lead for technicians in the territory.

Responsibilities include resolving escalated DC fast-charger faults; interpreting PLC, CAN, and OCPP logs; providing remote support to junior technicians; commissioning and acceptance-testing sites; executing upgrades and retrofits; maintaining test vehicles and interoperability testing; and managing preventive maintenance, reliability metrics, spares, failed-part returns, and warranty information. The technician also identifies recurring faults, documents root causes, writes service bulletins and procedures, trains and signs off junior technicians, and serves as the primary on-site contact for customers and other stakeholders.

The role requires adherence to NFPA 70E, NEC (including Article 625), local codes, and manufacturer specifications. Work includes job hazard analysis, lockout/tagout, arc-flash assessment, PPE selection, and use of stop-work authority. The technician must complete field reports and close tickets the same day, communicate issues and needs proactively, and maintain tools, test equipment, vehicle, and PPE in calibrated and inspection-ready condition.

This is a full-time, exempt position with Monday-to-Friday standard hours and a paid on-call rotation. Emergency dispatch and occasional weekend or after-hours work may be required when a site is down. Compensation is $75,000–$85,000 per year depending on experience, credentials, and platform depth; travel-day per diem and an on-call differential are paid in addition to base pay. Benefits include medical, dental, and vision coverage; 401(k); paid time off and holidays; a company vehicle, phone, laptop, tools, and PPE; and paid training and certification.
