At SPAN, we are building products to enable the rapid adoption of renewable energy. As more distributed energy resources like solar and storage come onto the grid, it’s increasingly important to be able to improve the technology that sits between the grid, the home, and those distributed energy resources. SPAN’s smart panel replaces the electrical panel to become the center for connected power in the home. With SPAN, homeowners receive all the safety features of a standard panel with revolutionary insights and edge-of-grid controls through our mobile app.
The RoleThe Mobile Team at SPAN builds consumer-facing iOS and Android applications that empower homeowners and installers to manage smart electrical panels, monitor energy consumption, and optimize renewable energy systems. As a Mobile Software Engineering Intern, you will contribute to building delightful, high-performance mobile experiences using React Native and Expo, working alongside experienced engineers on real features that ship to thousands of users.
