Job Advertisement: Researcher in Radio Wave Propagation

The Total Defence Research Institute (FOI) is a government agency conducting world-leading research in defense and security to support Sweden's military and civil defense. The research spans several areas, including underwater, cyber defense, space, electronic warfare, sensor systems, civil defense, CBRNe (chemical, biological, radiological, nuclear, and explosive substances), military platforms including weapons and protection, as well as security policy analyses. FOI's research plays a key role in building Sweden's defense capability.

Would you like to work with advanced applied research and development in a dynamic workplace at the forefront of technology? Then FOI could be your new workplace! We offer a work-life balance, a developing work environment, and a socially important job!

About the Position

Your tasks with us include wave propagation calculations in applied problems within the research and development of new radio-based systems in defense and security. We also develop efficient calculation models for radio wave propagation and implement them in computational tools.

The work is project-based in collaboration with other researchers both within and outside FOI. You will participate in dialogues with our clients and communicate results from completed activities.

Our projects are relatively small, which means your contribution will be an important part of the whole, and you will have a great opportunity to influence project results. You will have good opportunities to follow your idea from sketch to finished system, while also being able to follow the academic research in your field. If you want to take on greater responsibility, we are in a long growth phase, and there are good opportunities to take on the role of project leader.

Since we often verify our results in realistic environments with field measurements, it is a plus if you appreciate being outside of office and lab environments.

About the Unit

You will be part of the Robust Radio Communication unit, which belongs to the Electronic Warfare department. The unit covers a wide range of technologies, and there are therefore great opportunities for varied tasks. The military specific requirements, such as jamming resistance, uninterrupted operation, detection probability, along with high mobility, differentiate our operations from those normally conducted by other actors such as academia and companies. We work with radio communication for military users on frequencies from 10 kHz to 100 GHz in close collaboration with clients from all parts of the military defense to ensure high connectivity in peace, crisis, and war.

Do you have the competence profile we need?

Requirements

We are looking for someone who has:

• A Master's degree in engineering physics, electrical engineering, computer engineering, IT, or another equivalent education,
• Basic knowledge of electromagnetic wave propagation or good knowledge of numerical methods/mathematics
• Good ability to express yourself verbally and in writing in both Swedish and English

We want you to be an initiative-taking, self-driven, and structured person with good problem-solving analytical skills. We solve our tasks together and individually, which means you need to be able to combine independent work with frequent social interaction with colleagues.

We place great importance on your personal qualities.

Meritorious

We often work with broad issues, so it is meritorious, but not necessary, if you have knowledge in any of the following areas:

• Software development in Fortran or C++
• Signal processing for wireless communication
• Communication systems
• The defense domain, e.g., through previous employment, military service, military volunteer organization, or companies supplying to defense authorities
• Research education related to electromagnetic modeling, numerical methods, or mathematics

We want to make use of all your skills and interests, so please describe any other competencies you wish to continue developing with us.

What do we offer you?

The Total Defence Research Institute (FOI) is a government agency conducting world-leading research in defense and security to support Sweden's military and civil defense. We offer a unique workplace where you have the opportunity to work on what is important for total defense and society as a whole. The research is applied both within defense authorities and civil actors and plays a crucial role in building a relevant and effective defense capability.

We consciously work for a good work environment with a good balance between work and private life. In addition, we offer a range of benefits. Read more about what it is like to work with us: https://www.foi.se/jobba-hos-oss.html (https://www.foi.se/jobba-hos-oss.html)
