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! Heartbeat AI is our energy optimisation platform that always provides our customers with the cleanest and cheapest energy. As Chief of Staff to the Go-to-Market Director, you are the operational backbone that keeps the go-to-market engine running at full speed across all markets. You own the details, the data, and the day-to-day execution, freeing the Go-to-Market Director to focus on strategy and the bigger picture, while you make sure nothing falls through the cracks. You own the operational rhythm of the Go-to-Market Director's agenda, translating strategic priorities into concrete plans, timelines, and next-day action items. You track performance data and KPIs across all markets, spotting issues early and surfacing clear, decision-ready insights before being asked. You bring structure to ambiguity, designing the project management architecture, systems, and processes that keep complex, multi-market initiatives moving without anything getting lost. You proactively identify what needs to happen next, take ownership of it end to end, and know when to bring in the Go-to-Market Director to support or guide. You prepare briefings, reports, and presentations that turn complex data into clear narratives for leadership and cross-functional stakeholders. You coordinate closely with Product, Tech, Sales, and Marketing across markets, following up on commitments and ensuring cross-functional initiatives stay on track. You act as a trusted right hand, representing the Go-to-Market Director's priorities accurately in conversations and correspondence. You constantly look for ways to improve how the Go-to-Market function operates, bringing structure and rigour to a fast-moving, scaling environment. You bring at least 3 to 5 years of experience in a Chief of Staff, business operations, analyst, or similar high-rigour role, ideally within tech, scale-ups, or energy. You are exceptionally detail-oriented and accurate, with a natural instinct for catching what others miss. You are proactive by nature: you don't wait to be told what to do, you anticipate what's needed, take initiative, and only ask for help or authority when it genuinely matters. You have strong project management skills, able to build the architecture and structure that keeps complex, multi-market projects on track. You are highly structured and organised by default, able to juggle multiple workstreams and deadlines without losing the thread. You are strong with data and analytics, comfortable turning numbers into clear, actionable insight. You are a fast, reliable executor who thrives on turning big-picture priorities into next-day, on-the-ground action. Fluency in German and English (C1/C2) is required, written and verbal.
