Introduction
Short Facts
Join us on our journey to a smart and sustainable energy future!
We are seeking a proactive and driven Junior Portfolio Manager in Munich. You will support our battery energy storage system (BESS) portfolio, managing key client relationships and creating value through insight, connection, and innovation to drive customer success and growth.
Hi there! My name is Anton, and I’m the Lead of the Portfolio Management function at Entrix. Together with my team, I’m responsible for all of our existing customers, creating an exceptional experience for them - from regular interactions about the latest trading performance to sparring about the next BESS asset to be developed jointly. We’re excited to grow and would love to see your application! What drives me is the high level of responsibility, joint excitement and the trust that our customers place in us. The professionalism and personal connection that can develop between Entrix and our customers is what excites me. At Entrix, Portfolio Management is responsible for all customers that generate revenue — our communication and actions have a true impact on the success of our partnerships and both of our companies. I believe in extreme ownership, clear responsibility, and having each other's back. A growth mindset, trust, integrity and open communications are the principles I lead by. My goal is to create a team where everyone feels empowered to develop and thrive. If you’re passionate about driving meaningful change in the energy space and contribute to our joint success in a dynamic environment, we’d be thrilled to have you on board. Let’s make the energy transition real—together.
We are an energy trader and market leader for trading flexible energy systems in Europe.
Beyond AI-powered trading, Entrix provides innovative solutions for long-term revenue security and grid-supportive battery operation. With our full-service package, we support customers throughout every project phase – from technical design and integration, to continuous optimization, all the way to 24/7 operational support. That includes adapting to changing market conditions and unlocking new revenue opportunities.
Entrix is active in Germany, Poland, Italy, Spain, and Portugal, with offices in Munich, Warsaw, Milan, and Madrid. Since 2022, Entrix has been pioneering battery optimization in Germany by managing one of the country’s first large-scale storage projects – and is now the trusted partner of leading infrastructure players such as Encavis, MEAG (Munich Re), as well as a wide range of local utilities.
