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 about our Product & Tech team! Deine Position In tech we are building software systems in two main areas: * Heartbeat: Building a virtual power plant leveraging our energy manager "Heartbeat" and evolving the customer experience app around this. * Operating System for installation companies: Digitalisation of operations and processes from ground operations to rooftop installations. The data platform team designs and builds the foundation of how data flows through our company. Together with your team, you will forge new ways to ingest, process, store and deliver data both at scale and complexity. We focus on building tools that enable our internal customers to find, access and investigate data for any of their use cases.
