Principal Software Engineer (m/f/d)

<br><strong>1KOMMA5°</strong><p><span style="font-family:Arial, Helvetica, sans-serif;font-size:14px;">At <strong>1KOMMA5°</strong>, we pursue a clear vision: <strong>Living on wind and sunlight forever for free</strong>. To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it?<br>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.<br><br><strong>Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.</strong><br><br>Learn <a href="https://1komma5.com/de/ueber-uns/jobs/tech/">more</a> about our Product &amp; Tech
