Renewable Energy Sector

Design the power systems that will drive the energy transition.

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.
