Working Student - AI Product Designer (m/f/d)

1KOMMA5°

At 1KOMMA5° , we pursue a clear vision: Living on wind and sunlight forever for free . To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?

We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective.

By 2030, our goal is to transition 1.5 million households to renewable energies. Over 2,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.

Your mission

We are looking for an AI-native designer working student to embed directly into our B2C mobile app team. You won't be doing side tasks; you'll be shaping our flagship consumer product, the Heartbeat app.
