Job description

Come join SG Inc., an electrical infrastructure company specializing in utility-scale and commercial renewable energy construction. This is an opportunity to work at the center of the energy transition—pricing complex solar, storage, and medium-voltage projects that win, while collaborating with an execution team where your technical precision directly drives profitability.

Responsibilities

We are building a high-performance estimating team and looking for a Solar Electrical Estimator who is sharp, fast, and thorough. You will evaluate project drawings, single-line diagrams (SLDs), and geotechnical reports to prepare detailed takeoff packages across DC, AC, and Medium Voltage systems. If you thrive in a competitive EPC environment where bidding accuracy, production rates, and heavy equipment logistics matter, you’re looking in the right place.

Qualifications / Requirements

• Solar & MV Cost Estimating: Proficient in solar electrical estimating, cost control, labor productivity modeling, and market commodity trends (copper/aluminum, transformer lead times, steel logistics) to ensure winning bids and rock-solid project budgets. Proven record of winning profitable projects
• Codes & Utility Standards: Strong knowledge of utility-scale electrical practices, NEC (specifically Articles 690, 691, and 705), NESC, and regional interconnection requirements.
• Solar Systems Engineering: Solid foundation in solar electrical engineering principles—including DC string design, combiner/recombiner sizing, inverter skids, CAB suspension/underground collection, and MV collector substation interfaces.
• Quantification & Logistics: Excellent analytical and mathematical skills for precise calculations of cable pull lengths, voltage drop/loss analysis, trenching/backfill quantities, and heavy rigging/crane picks.
• Estimating Software: Proficiency in electrical estimating software (Accubid, B2W, HCSS, or similar) and civil/BIM takeoff tools.
• Able to utilize resources to quickly produce 10%-60% design budgets.
• Cross-Functional Communication: Effective communication, negotiation, and collaboration skills to engage with developers, equipment OEMs, subcontractor networks, and internal project managers. Able to train and mentor junior estimators
• Education: Bachelor’s degree in Electrical Engineering, Construction Management, or a related field preferred.
• Experience: Relevant experience estimating utility-scale PV, commercial solar, energy storage (BESS), medium-voltage electrical distribution infrastructure, communication networks and is up to date on emerging technologies.
