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.

Your mission As part of our Mobile App Platform team, you will own the quality strategy of our Flutter apps, and change how we approach testing. AI-driven QA is the differentiator in this role. Our QA team already uses AI for test generation, but we want to go much further. You will help reinvent it: autonomous exploration, smarter test orchestration, self-directed QA workflows, and QA systems that detect product risks before they reach users. This is not a "write test cases and file tickets" role. You co-create systems and practices that enable our product teams to own product quality end-to-end and work with them to close the gaps so we can ship with confidence. Speed boost instead of speed bump. You think about quality as something you design into the product and process, not a checklist you run before release, effectively shifting quality assurance left.

1KOMMA5&deg; was founded in summer 2021 by entrepreneurs and industry experts with the aim of making buildings holistically CO2 neutral through the use of photovoltaics, heat pumps and charging infrastructure. This is implemented by providing technology for decentralized, clean energy, mobility and heat supply. Thanks to the intelligent energy management &ldquo;Heartbeat&rdquo; and the dynamic electricity tariff &ldquo;Dynamic Pulse&rdquo;, 1KOMMA5&deg; always guarantees the cheapest and cleanest electricity from sun and wind. 1KOMMA5&deg; participates in particularly innovative craft businesses in the areas of photovoltaics, electricity storage, charging infrastructure and heat pumps, on the one hand to strengthen regional crafts and on the other hand to enable high-quality advice and installation at the customer's site. 1KOMMA5&deg; currently operates over 65 locations with around 1,500 employees from Europe to Australia. In addition, 1KOMMA5&deg; is working on networking and controlling decentralized generation systems with the aim of fully realizing the potential of the decentralized energy transition. For this purpose, all installed systems become part of a networked IoT platform, which uses algorithms to guarantee optimal, automatic operational management over the life of the system.
