About the Role

We’re seeking a Senior Solar Systems Design Engineer with at least 5 years of experience to lead the engineering and design of solar + storage systems for commercial and industrial projects. This is a high-impact role working on technically complex projects featuring cutting-edge technology, including Tesla Megapacks and advanced inverter systems.

This is more than a design position — it’s a growth opportunity. If you’re a high performer who can lead cross-functional projects, communicate effectively across teams, and deliver innovative solutions, you’ll have the potential to advance into a leadership role.

Key Responsibilities

• Conduct site walks and evaluate feasibility for PV + ESS projects.
• Gather and analyze site data (electrical, structural, environmental).
• Lead detailed system designs, including site plans, SLDs, conduit schedules, and interconnection packages.
• Use tools like PVSyst, Helioscope, HOMER, and SAM for modeling and performance estimates.
• Ensure designs meet NEC, CEC, UL, IEEE, and utility standards.
• Coordinate with project managers, utilities, permitting authorities, and construction teams.
• Support permitting, interconnection, and commissioning activities.
• Set and refine internal CAD standards; oversee drafting workflows.
• Drive continuous improvement of design templates and engineering processes.

Qualifications

• B.S. in Electrical Engineering or related field.
• 5+ years of experience designing solar PV and energy storage systems.
• Proficiency in AutoCAD, PVSyst, and one-line diagram development.
• Familiarity with DC/AC coupled systems and energy storage integration (Tesla, Fluence, PCS, etc.).
• Strong knowledge of NEC 690/705/706, UL 1741-SA, IEEE 1547.
• Experience with IOU interconnection processes (PG&E, SCE, SDG&E, etc.).
• Excellent documentation and communication skills.
• EIT or NABCEP certification a plus.
• 1+ year of team leadership or mentoring experience preferred.

Why is This a Great Opportunity

• Work on high-profile, innovative renewable energy projects.
• Collaborate with a forward-thinking, mission-driven engineering team.
• Opportunity for career advancement into leadership.
• Competitive salary, full benefits, and professional growth support.
