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.

Deine Position

As Product Manager Procurement & Portfolio Management, you take on one of the most strategically defining product roles within our energy retail business: you design how 1KOMMA5° procures, hedges, and optimizes electricity for an increasingly flexible customer portfolio. You sit at the intersection of energy markets, energy procurement, our flexibility assets, and our customer-facing tariff strategy - and you turn this into a measurable commercial advantage.

• Own our Procurement Strategy: Define how and where 1KOMMA5° procures energy for our customer portfolio - across day-ahead, intraday, and forward markets. Develop a clear market split logic, and continuously refine it based on portfolio characteristics, customer mix, and market conditions.
• Design Portfolio Hedging & Risk Management: Build hedging and risk management strategies tailored to different customer portfolios (dynamic vs fixed tariffs or flexibility/ancillary services). Define when and how we lock in volumes, what we leave open, and how we balance commercial upside against risk exposure.
• Shape Our Flexibility Procurement Model: Design how we procure and steer our flexibility portfolio. Defining models such as flexibility bands, fixed volumes, strike-price-based offers, and the trade-offs between them. Develop the commercial logic and the operational requirements for each model.
• Run Quantitative Portfolio Analysis: Independently run analyses on procurement performance, hedging effectiveness, and portfolio economics. Build the analytical foundation that supports strategic decisions, identifies optimization opportunities, and quantifies the impact of changes to our procurement and steering setup.
• Monitor Performance and Drive Continuous Improvement: Define KPIs across procurement cost, hedge effectiveness, portfolio risk, and flexibility margin. Use data to continuously sharpen our market positioning and commercial performance.
