Job Description

Field Service Technician – Utility-Scale BESS

Location: Salome, AZ - Full time, On-site

Join a project that sets the standard for modern energy storage.

We are hiring Field Service Technicians to support a brand-new 1.8 GWh utility-scale Battery Energy Storage System (BESS) site near Salome, AZ. This is the largest BESS deployment in the U.S., and it offers hands-on involvement with cutting-edge, U.S.-manufactured LFP technology from a Tier 1 battery OEM and system integrator.

What Sets This Role Apart

• Fully integrated systems: All battery cells, containers, inverters, controls, and services are designed, built, and supported by one company, eliminating the inefficiencies of multi-vendor projects.
• Mission-critical work: You’ll be supporting the single largest energy infrastructure project in the country, with a direct impact on grid reliability and renewable energy integration.
• Structured growth path: The site is expanding rapidly, doubling the field service crew from 6 to 12 engineers and technicians over the next year. High performers will have early opportunities for full-time roles and advancement into engineering tracks.

Key Responsibilities

• Support day-to-day operations, preventive maintenance, and inspections on BESS equipment.
• Assist senior field engineers with system troubleshooting, inverter/PCS diagnostics, and firmware updates.
• Document all site activities, maintenance tasks, and performance checks with accuracy.
• Follow and enforce strict safety standards, including Lockout/Tagout (LOTO) protocols.
• Collaborate closely with the OEM’s service team to ensure maximum uptime and operational reliability.

Qualifications

• Hands-on experience with electrical, mechanical, or industrial controls systems (industrial maintenance, renewables, semiconductor, backgrounds are transferrable skills).
• Basic ability to read and interpret electrical schematics and wiring diagrams.
• Strong commitment to safety, teamwork, and professional communication.
• Comfortable working in a remote desert environment with extreme temperatures.
• OSHA 10 and NFPA 70E certifications are a plus.

What We Offer

• Above-market pay rate with overtime opportunities
• Hands-on experience with cutting-edge, U.S.-manufactured LFP technology at the largest BESS site in the country.
• Professional-grade tools, PPE, and comprehensive site training provided by the OEM.
• Career-building exposure – work directly with a Tier 1 battery manufacturer and system integrator, gaining skills and experience that set you apart in the energy storage sector.
• Team-first environment – join a tightly coordinated field crew with clear direction and support, not a subcontractor free-for-all.

If you’re ready to build your career in energy storage with a team that owns the entire system from cell to site, we encourage you to apply.
