How to Apply for Working Student Frontend / Fullstack Software Engineering (m/f/d)

at 1KOMMA5°

🏢 About 1KOMMA5°

1KOMMA5° is pioneering holistic CO2-neutral building solutions that integrate decentralized clean energy, mobility, and heat supply. This makes them unique as they're tackling climate change through practical, integrated technology rather than isolated solutions. Working here means contributing directly to sustainable infrastructure in Germany while being part of a remote-first team focused on meaningful environmental impact.

About This Role

As a Working Student Frontend/Fullstack Engineer, you'll collaborate with product managers and designers to implement and deploy software solutions for sustainable building management systems. You'll take end-to-end ownership of features that directly improve customer satisfaction through clean energy and mobility solutions. This role is impactful because you'll be building the digital interface that enables CO2-neutral living for German households and businesses.

💡 A Day in the Life

A typical day involves collaborating remotely with product managers to refine feature requirements for energy monitoring dashboards, then implementing React components with TypeScript for real-time data visualization. You might spend time writing tests for new features, reviewing pull requests from team members, and deploying updates via Vercel to improve the user experience of 1KOMMA5°'s sustainable building platforms.
