Strategic Partner Manager

About Us
Sunstone Credit is on a mission to revolutionize commercial solar finance.

Sitting at the intersection of climate, finance and technology, Sunstone is opening the door to a previously underserved segment in the solar industry by offering financing solutions that help businesses save money and reduce their carbon footprint by going solar.

Founded in 2021 by successful serial founders, Sunstone has a strong backing from top VC firms and financial institutions that position our company for explosive growth in 2025 and beyond. In late 2023, we seized an opportunity to accelerate entry into the residential segment through the acquisition of Sunlight Financial.

We have partners and customers that are diverse, and we are building a team that reflects that. Our team members collaborate and innovate from our HQ in NYC’s Flatiron District and every one of our colleagues shares in Sunstone’s success with meaningful equity ownership.

Climate change is the greatest challenge humanity has ever faced. We are doing our part to stop it. This is not just a job, it’s a mission – true believers only. Come join our team!

About the Role
Location: Sunstone's New York City Office (Hybrid role, Tue-Thu in-office)

Target Compensation: $125k+ (Base and Bonus)

Sunstone is seeking a Strategic Partner Manager to join our team. Sunstone's partners are solar installers and developers selling solar systems to and installing solar systems for businesses.

You can expect significant autonomy in a fast-moving, evolving industry, with the opportunity to shape both your role and our partner strategy as Sunstone grows. Join us in building an agile, partner-focused, values-driven company.
