Our Mission
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 Role
The 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.
Responsibilities
Build and enhance features for the Homeowner and Installer mobile apps using React Native, Expo Router, and TypeScript
Create polished UI components following our component library patterns and accessibility best practices
Write high-quality tests (unit, integration, and snapshot tests) using Jest and React Testing Library
Collaborate with designers to implement intuitive interfaces for complex energy management workflows
Participate in code reviews and contribute to architectural discussions with the mobile team
Debug and optimize app performance, addressing issues like render performance, bundle size, and startup time
Potential Projects
As we are a startup, this list should be considered neither exhaustive nor complete. We are excited for people to explore responsibilities outside their normal areas of expertise if the need or interest arises.
Implement new panel visualization features to help homeowners understand their energy usage
Build installer workflow screens for configuring circuits and breakers during panel setup
Create reusable UI components for the shared component library
Improve test coverage for critical user journeys in the app
Optimize app performance for smoother animations and faster load times
