Field Service Technician - Level 3

About Us

We are a leading provider of emergency backup power solutions across Northern California and Nevada, specializing in generator sales, service, installations, and maintenance for commercial and industrial clients. Our mission is to keep the lights on when our community needs it most — especially for the critical infrastructure that powers our digital world.

Position Overview

We are seeking a Senior Field Service Technician (Level 3) to join our Industrial Service Team, with a specific focus on automatic transfer switches and generator control systems. This is a role for a seasoned technician who has seen it all — someone who can walk onto a site, diagnose a complex transfer or control issue, and resolve it right the first time.

You will work in high-stakes environments where downtime is not an option. Strict adherence to method-of-procedure protocols, impeccable site etiquette, and a "first-time right" approach are essential. As a Level 3 technician, you'll also serve as a technical resource and mentor to junior team members.

While transfer switch and controls mastery is what sets this role apart, this remains a hands-on field service position. The right candidate takes pride in doing the fundamentals well — preventative maintenance, oil and filter changes, load bank testing, and routine service — and never considers that work beneath them. We're looking for a senior technician who brings specialized expertise while still rolling up their sleeves alongside the team.

Key Responsibilities

• Transfer Switch Expertise: Install, service, troubleshoot, and repair automatic transfer switches (ATS) across a range of manufacturers and configurations.
• Generator Controls: Diagnose, program, and calibrate generator control systems and instrumentation, resolving complex control and communication faults in the field.
• Controller Upgrades: Support and perform generator controller upgrades and retrofits to modern control platforms (a strong plus).
• Mission-Critical Maintenance: Perform preventative maintenance and repairs on large-scale industrial generators and associated switchgear.
• Advanced Testing: Lead load bank testing and system functional testing to ensure reliability of backup power systems.
• Professional Communication: Provide clear, technical debriefs to facility managers and internal engineers, maintaining a high standard of conduct in demanding environments.
• Emergency Response: Participate in a rotating 24/7 on-call schedule, responding with urgency to critical power failures.
• Documentation: Maintain meticulous records of service reports, sensor calibrations, and system parameters to meet strict audit requirements.
• Mentorship: Serve as a senior technical resource, guiding and training Level 1 and Level 2 technicians.

Qualifications

• ATS Experience (Required): Extensive hands-on experience installing, servicing, and troubleshooting automatic transfer switches. This is the core of the role and a non-negotiable requirement.
• Generator Controls (Strongly Preferred): Solid working experience with generator control systems — programming, calibration, and fault diagnosis.
• Controller Upgrades (Preferred): Experience performing generator controller upgrades or retrofits to modern control platforms.
• Technical Mastery: Deep understanding of electrical systems, control wiring, and instrumentation. Familiarity with paralleling switchgear and high-voltage configurations is a bonus.
• Professionalism: Exceptional soft skills and a polished demeanor; the ability to represent the company effectively in high-security, high-pressure environments.
• Precision & Detail: A disciplined approach to following complex technical manuals and site-specific procedures without deviation.
• Logistics: Valid driver's license and the ability to travel across Northern California and the Central Valley for on-site service.
• Physical Ability: Capable of navigating industrial settings and lifting up to 50 lbs. (occasionally up to 100 lbs.).
