Your Position
1KOMMA5°
At 1KOMMA5°, we pursue a vision: Living on wind and sunlight forever for free. To achieve this, we are building the energy system of the future with Heartbeat AI. Are you in?
We combine regional craftsmanship and scalable software: we don't think about solar, storage, heat pumps, and e-mobility individually, 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's renewably available and particularly cheap. By 2030, we want to convert 1.5 million households to renewable energy. Over 3,000 people work on this every day, at more than 80 locations worldwide, from Finland to Australia.
Do you want to take responsibility and build solutions that truly matter? Apply now and shape the energy world of tomorrow with us.
As a working student in Data Analytics at 1KOMMA5°, you will support the Controlling and Business Intelligence teams in building a central data architecture that ingests, transforms, and analyzes data from our global operational and financial business. In doing so, you will help generate actionable insights for financial planning, performance tracking, and strategic decision-making processes across the entire company.
The most important tasks include:
- Building and maintaining end-to-end data pipelines to ensure the availability of operational and financial data
- Supporting the Controlling team with automated reports, forecast datasets, and KPI tracking
- Independently developing analyses, dashboards, and reports in Looker to monitor financial and operational performance
- Contributing to ensuring data integrity and reliability in financial datasets
- Assisting with the automation and optimization of reporting processes for budgeting, forecasting, and variance analyses
- Investigating and applying AI-powered data analysis to improve forecasts, anomaly detection, and business insights
