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 3,000 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. Learn more about our Product & Tech team!
Deine Position
Heartbeat AI is our energy optimisation platform that always provides our customers with the cleanest and cheapest energy. Great go-to-market starts with understanding our customers, and the best way to do that is to talk to them.
As a Customer Engagement Working Student on the Go-to-Market team , you reach out by phone to customers at key moments in their journey, check in on how things are going, and find out whether there is anything we can do to help. This is not a sales role. It is a listening and support role, where your conversations give the Go-to-Market team a first-hand view of the customer experience across our markets. You will support initiatives end to end, and your insights will directly feed decisions that go to Product, Sales, and Marketing, helping us sharpen our positioning, messaging, and customer journey.
