Stora Enso
The forest is at the heart of Stora Enso and we believe that everything made from fossil-based materials today can be made from a tree tomorrow. We are the leading provider of renewable products in packaging, biomaterials, and wooden construction, and one of the largest private forest owners in the world. We create better choices for society by accelerating the transition to a circular bioeconomy. We aim to contribute positively to nature, and have the most effective use of fiber-based renewable material. Stora Enso had approximately 19,000 employees at the end of 2024.
Be part of a nature-positive future.
Every year, we offer hundreds of diverse summer job opportunities for talents from various fields. Are you enthusiastic and motivated to work in a global company producing renewable materials? In the coming years, wood- and bio-based solutions will be used in entirely new ways, giving us the opportunity to grow. A summer job in one of our units is an excellent way to start your career at Stora Enso and grow with us. We hire summer employees for roles such as process operators, production planning, forest specialists, laboratory work, operations and maintenance, and various expert positions across Finland.
Each year, many students also complete their thesis or final project at Stora Enso – often related to our renewable material solutions. A successful summer job can even lead to a thesis opportunity.
