Senior Electrical Commissioning Engineer – Protection & Controls | If you’re the engineer everyone calls when the power won’t come online…keep reading.

If terms like SEL relays, protection & controls, commissioning, switching plans, substations, and utility-scale solar are already part of your world, we should talk.

You’ll provide onsite engineering support for commissioning, relay protection, outage planning, equipment evaluations, and field troubleshooting at the Constellation Antelope Valley Solar Ranch in Lancaster, CA. This is a high-impact, hands-on assignment supporting one of California’s premier renewable energy facilities alongside Sargent & Lundy.


If you’re in the right profession, but the wrong environment, we may have exactly what you’re looking for.

We’re looking for experienced electrical field engineers with:

  • 8+ years of commissioning, protection & controls, or power systems experience
  • Utility-scale solar, substation, or power generation experience
  • Strong relay protection and high-voltage switching knowledge
  • Ability to read one-lines, protection schematics, and electrical drawings
  • Experience solving problems in the field—not just from the office

Assignment Highlights

  • Location: Lancaster, CA (Onsite)
  • Duration: 3-month contract with extension potential
  • Schedule: 40 hours/week
  • Per Diem: $250/day
  • Vehicle Allowance: $1,800/month
  • Mobilization/Demobilization: $1,500 each
