Compensation: $110000-$140000
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.
