We’re looking for a Principal Electrical Engineer to lead the design and implementation of cutting-edge clean energy systems — from utility-scale solar PV and battery storage to EV charging infrastructure and microgrids. You’ll own the full engineering lifecycle, shape grid-interconnected solutions, and work on high-impact projects that power schools, cities, and businesses with clean energy.

If you're a licensed California PE with deep experience in electrical systems and a passion for sustainability, we want to hear from you.

What You’ll Do

• Lead the design of solar PV, battery storage, off-grid microgrids, and EV charging systems.
• Develop full construction drawing sets, including single-line and three-line diagrams, in compliance with NEC, IEEE, and utility interconnection requirements.
• Perform interconnection studies, prepare application packages, and create dynamic system models .
• Conduct power system studies, including load flow, arc flash, short circuit, harmonic analysis , and protective device coordination.
• Visit job sites to assess electrical infrastructure and identify optimal ESS, PV, and EVCS installation locations.
• Manage vendor relationships and integrate innovative DER technologies into scalable solutions.
• Collaborate with clients, utilities, and contractors to resolve RFIs, code issues, and design changes.
• Write compelling technical reports and proposals that explain complex energy solutions in simple terms.
• Ensure every design complies with safety codes and aligns with client, jurisdictional, and utility standards.

What You Bring

• California PE license (Required)
• 5+ years of hands-on experience in power distribution, utility interconnection, or DER systems
• Expertise in system design for solar PV, energy storage, EV infrastructure, and/or microgrids
• Strong knowledge of electrical codes and utility interconnection procedures
• Experience using ETAP, SKM, or similar tools for power studies and system modeling
• Familiarity with developing bills of material , equipment specs, and routing plans
• Ability to balance big-picture vision with technical depth and attention to detail
• Exceptional communication skills to engage with clients, regulators, and cross-functional teams

Why Join Us?

• Help accelerate the shift to clean energy by working on large-scale, high-visibility projects.
• Be part of a tight-knit, mission-driven engineering team tackling some of the most complex power system challenges in the industry.
• Enjoy autonomy, innovation, and leadership opportunities in a fast-growing sector.
• Competitive salary, full benefits, and long-term career growth.
