Field Service Technician II – Solar

About the role

Energy Support Services keeps solar and energy storage systems safe, reliable, and producing clean power. As a Field Service Technician II – Solar, you'll work independently on advanced inspections, preventative maintenance, and system troubleshooting — operating safely in high-voltage environments without direct supervision, guiding junior technicians on site, and progressing along a defined pathway toward Technician III.

Work arrangement

This role is performed in person, outdoors, on solar sites in and around St. Louis, Missouri. You must already live within commuting distance of St. Louis, or be prepared to relocate there at your own expense before your start date. This is a field-based position — you drive from your home to job sites rather than reporting to an office each morning. Territory: 30–90 minutes typical, rarely over 3 hours. Overnight travel: under 10%. Schedule: Monday–Friday, 7am–3pm or 8am–4pm. On-call: rotational Saturday 8am–12pm. Overtime: paid biweekly; 40–45 hours typical; 1.5x over 40.

What you'll do

• Safety — Lead by example in promoting a safe working culture in the field. Perform approved hazardous electrical energy control procedures and select the exact PPE required for each task. Participate in and actively critique Pre-Job Briefs and Job Safety Analysis (JSA). Apply personal lockout/tagout as a worker, or serve as work leader once approved.
• Inspections and preventative maintenance — Perform comprehensive electrical and mechanical inspections of solar energy systems. Conduct advanced preventative maintenance including infrared thermography, insulation resistance testing, and I/V curve tracing — all of which we train you on. Help build and implement preventative maintenance schedules for your assigned sites.
• Troubleshooting — Independently diagnose and troubleshoot system and operational issues. Operate and troubleshoot safely in 600VAC and 1500VDC environments without direct supervision. Use specialized diagnostic tools and root-cause analysis to handle equipment repairs and replacements.
• Documentation — Create and maintain detailed, accurate records of inspections, maintenance, and repairs with minimal oversight. Prepare clear technical reports and actionable equipment recommendations for the Team Lead.
• Knowledge sharing — Stay current on industry best practices, safety updates, and emerging technology. Share your expertise and give supportive guidance to junior technicians on site. Help improve the quality, clarity, and safety content of our training materials. Support your teammates and take on other duties as assigned.

Required qualifications

• High school diploma or equivalent.
• 2+ years of hands-on technical, electrical, or mechanical work in any industry — solar, electrical, automotive, diesel, HVAC/R, telecommunications, wind, power generation, industrial maintenance, utilities, or a military technical specialty.
• Solid working understanding of electrical fundamentals — AC and DC theory, series and parallel circuits, grounding, and safe work practices around energized equipment.
• Confident with a multimeter and able to read, interpret, and work from electrical schematics or engineering drawings.
• Strong analytical, time management, and problem-solving skills, and a track record of working independently without someone checking on you.
• Strong communication skills and the patience to bring a junior technician along.
• Valid driver's license and clean driving record.
• Applicants must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of employment visas at this time.

How your background translates from other trades

• Automotive, diesel, or heavy equipment — Root-cause diagnosis, circuit tracing, reading schematics, using a scan tool and DMM, working to torque spec, and writing up findings. You'll trade flat-rate for a salary, and your tool box for ours.
• HVAC/R, especially commercial or light-industrial — Control circuits, contactors, VFDs, three-phase power, service calls run solo, and preventative maintenance on a schedule. Very close cousin to this work.
• Telecommunications, broadband, or utility line work — Working at height, terminations, test equipment, prints, and outdoor work in every kind of weather. Your safety habits are already right.
• Industrial maintenance, wind, or power generation — Lockout/tagout discipline, medium-voltage awareness, PM programs, and CMMS documentation all carry directly across.
• Military technical specialties — Power generation, electrical systems, avionics, and electronics maintenance transfer cleanly.

Tools you'll learn (and equivalents you may already know)

• I/V curve tracer — measures the performance curve of a string of solar modules to find underperformance. Conceptually similar to putting a vehicle or motor on a load test.
• Megohmmeter ("Megger") / insulation resistance tester — finds insulation breakdown and ground faults. If you've used one in industrial or motor work, it's the same instrument.
• Infrared thermography — thermal imaging to find hot spots in connections and modules. If you've used a thermal camera on bearings, panels, or refrigerant lines, you're already there.
• Drone-based aerial thermal inspection — we pay for your FAA Part 107 and teach you the flight work.

Pay

$75,000 – $95,000 annually, depending on experience and qualifications.

Benefits

• Tools and equipment: provided. Company truck, company fuel/credit card, and vehicle maintenance card. You will never spend your own money on tools here — no tool truck payment, no tool debt.
• Bonus: Up to an 8% performance bonus, paid annually.
• Apparel: Company-provided PPE and flame-resistant clothing kit (bibs, jackets, pants, shirts) at no cost to you.
• Health: Medical, dental, and vision. We pay 80% of your health insurance premiums.
• Retirement: 401(k) with up to a 7.5% company match.
• Time off: PTO accrued each pay period — 120 hours/year (years 0–2), 160 hours (years 3–9), 200 hours (10+ years) — plus 11 paid holidays.
• Family: 8 weeks of paid parental leave.
• Insurance: Company-paid Life and AD&D insurance at 1x your annual salary.
• Certifications — we pay, you keep them: OSHA 10/30, NFPA 70E/70B, FAA Part 107 (drone), and our internal O&M Tech course series. These certifications stay with you for the rest of your career.
• Advancement: A published Field Tech Development Pathway with defined progression to Technician III. You move up on demonstrated capability, not on how long you've been here.
• Education: Tuition reimbursement up to $10,000 per year for approved programs.

Helpful (but we'll train and certify you)

• Solar-specific or grid-tied PV system experience.
• FAA Part 107 drone certification — we pay for it.
• OSHA 30 and NFPA 70E — we pay for these as well.
• Hands-on time with I/V curve tracers, megohmmeters, or insulation testers — or comparable diagnostic instruments from another trade.
• Familiarity with Data Acquisition Systems (DAS) or SCADA — the monitoring systems that report site performance remotely.

Physical requirements

• Drive a vehicle confidently and with a high degree of safety.
• Stand for long periods and walk distances up to three miles per day.
• Navigate ladders, stairs, scaffolding, and ramps while maintaining three points of contact.
• Have visual acuity for depth perception, no field-of-vision issues, and the ability to distinguish between colors.
• Work comfortably in a range of climate conditions, including extreme heat (above 100°F) or extreme cold (below 32°F), for periods of more than one hour.
• Exert up to 50 pounds of force occasionally, up to 30 pounds frequently, and up to 10 pounds constantly to move objects.
