FOI's research plays a key role in building Sweden's defense capability.

Do you want to be part of an exciting technical and scientific environment – where curiosity, collaboration, and creativity are at the center? At FOI, you will work with advanced technology that makes a tangible difference for Sweden's defense and security. We are a team of dedicated researchers and engineers who combine theory, experiments, and analysis to find smart solutions to real problems.

About the Position

As a researcher with us, you will work at the forefront of development, but also in a supportive and learning environment. You will conduct applied research for the benefit of our clients in the defense sector.

This means you will further develop your skills with us. This can happen both within the framework of the research activities and in the form of individually tailored skills development based on your and the organization's needs. We are looking for someone who is curious and solution-oriented, with an interest in working at the intersection of theory and practice.
