Senior Full-Stack Engineer (Ruby on Rails)

About Wunder Wunder is building a Modern Energy Company. We were founded with one simple vision: to address the greatest crisis of our generation by accelerating the deployment of solar energy. In doing so, we help businesses, municipalities, and schools save money by delivering clean on-site power. We convert simple warehouses into electrified industrial platforms built for the future. We enable the nation’s leading commercial and industrial real estate firms to capture the benefits of solar across their properties. We align ESG goals with revenue targets, and the renewable energy assets we’re deploying today will power America’s tomorrow. Wunder is actively developing hundreds of commercial solar projects across the country. Our team has evaluated more than 30,000 properties for solar across all 50 states to meet our customers where they are. Our customers have a national footprint and so do we. Wunder’s proprietary technology platform enables us to develop solar at scale, across a portfolio that includes everything from self-storage facilities and schools to data centers and industrial logistics facilities. Our average solar system—about 430 kilowatts in size—can offset 350,000 pounds of coal burned each year of system operation! The Role At Wunder, we're building a team of high-performing, effective, and sophisticated engineers.
