Job Description

Do you want to contribute to a fossil-free future? Do you have experience in software development and an interest in nuclear physics while enjoying a role where you can utilize your analytical skills and develop your technical expertise?

Vattenfall Nuclear Fuel (VNF), part of the Vattenfall Power Solutions (VPS) business unit, plays a crucial role in Vattenfall's work towards fossil-free energy. Our mission is to procure, size, and deliver nuclear fuel to Vattenfall's nuclear power plants. We also provide technical analyses and other expert services in the nuclear fuel area. At VNF, several experienced and dedicated teams work together, bringing various backgrounds and perspectives to achieve our common goal of delivering nuclear fuel to Vattenfall's nuclear power plants and creating conditions for a fossil-free future.

The unit “Methods & Systems” adapts external software to the fuel that VNF procures, as well as creates its own programs and tools that support the core and fuel operations at Vattenfall. These handle parts of technical analyses in areas such as reactor physics, safety analysis, and thermohydraulics. In addition, we manage and develop a few administrative software applications. Within the unit, we combine technical expertise and innovative solutions to drive development forward – both for our work and for the future of energy supply.

There is currently an initiative within VNF and VPS to implement several projects in the areas of artificial intelligence and machine learning. This entails greater responsibility for development in this area and an opportunity to steer the direction of this initiative. Relevant areas include numerical methods such as neural networks, as well as language models and their applications.

We offer you the opportunity to work on exciting, complex, and challenging projects within the nuclear power industry. You will be part of a highly competent team that values collaboration, a positive work environment, and a strong sense of community. We also provide good opportunities for further development in related areas, where your development and learning are the focus. When you start with us, we ensure you receive a thorough introduction, learning from our experienced and dedicated colleagues. Here, you will find a workplace where both your development and well-being are priorities. With us, you will have the trust to act with great freedom and responsibility, which, along with good working conditions and mutual trust, provides high flexibility and balance between work and private life.
