How to Apply for Staff Mobile Developer

at SPAN

🏢 About SPAN

SPAN is revolutionizing clean energy adoption by creating intuitive home interfaces that make sustainable living accessible. Unlike traditional energy companies, they focus on user-friendly technology that puts control directly in homeowners' hands through their smart panel system. Working at SPAN means contributing to tangible climate solutions while building products that reach millions of homes.

About This Role

As Staff Mobile Developer at SPAN, you'll architect the mobile experience that connects users to their home energy systems, serving as the technical leader for React Native development. This role directly impacts SPAN's mission by creating the primary interface through which customers interact with their energy systems, requiring both deep technical expertise and strategic influence across product, design, and hardware teams.

💡 A Day in the Life

A typical day involves collaborating with product managers on upcoming features, pairing with engineers on React Native implementations, reviewing architecture decisions for upcoming migrations, and troubleshooting integration issues with firmware teams. You might spend mornings refining testing strategies and afternoons mentoring team members on best practices while ensuring deployments maintain reliability standards.
