Can you turn complex data into decisions that shape the future of offshore wind?

At Vattenfall, there is a way. A way to accelerate the energy transition through innovation, collaboration and smart decision-making. As a Wind Farm System Designer, you will help define the design and value of some of Europe's largest offshore wind projects, influencing investment decisions worth billions of euros and contributing directly to a more sustainable energy system.

Working closely with experts within interdisciplinary teams, you will perform techno-economical assessments to create value while supporting the continued growth of renewable energy.

Your responsibilities include:

• Performing techno-economic assessments to evaluate offshore wind farm concepts, quantify key value drivers, and support strategic project and portfolio decisions.
• Developing offshore wind farm designs, balancing energy production, cost, technical feasibility, environmental constraints, and project requirements.
