Mechanical Testing and Certification Engineer

Pegasus Solar is the fastest-growing provider of proprietary solar mounting hardware and project design software in the U.S. In 2025, we'll manufacture and ship more than 13 million parts — with a Pegasus system installed once per minute.

We're a tight-knit, high-impact team driven to accelerate solar deployment by making it simpler, faster, and better. Founded in 2012, Pegasus partners with installers to design and engineer products that improve installation efficiency and long-term reliability. With 180+ patents issued/pending and 500,000 systems installed, we continue to set the standard for innovation and reliability in solar. Our mission is to give installers a better day on the job — and system owners a better product for life.
