Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has an annual turnover of over SEK 2.3 billion. We are more than 1,800 employees and have nearly 21,600 students.The Department of Systems and Space Engineering, where the university has gathered research and education in space technology, control engineering, computer and systems science, is now looking for assistant lecturers who can contribute to our growing activities. The job placement is at the Department of Space Technology in Kiruna. The division offers a number of master's programs in space science and technology. We conduct research in the fields of atmospheric science and space systems. The Space Systems group focuses on payloads, spacecraft and launch vehicles for the exploration of the upper atmosphere, orbits and planets. The research and teaching carried out is supported by high quality infrastructure with state-of-the-art laboratories dedicated to rocket propulsion systems, nano satellites, asteroid engineering and space avionics. Subject description Space systems include systems for regulation, control, instrumentation and communication in the upper atmosphere and space. Of particular importance are reliable electronic systems with low power consumption, radiation resistance and their miniaturization. Project description In 2025, Luleå University of Technology has started a multidisciplinary competence center together with KTH and RISE in 6G and satellite communication, Sustainable Mobile Autonomous and Resilient 6G SatCom. Ericsson, Saab, Ovzon, Beyond Gravity, Forsway, Satcube, Swedish Space Corporation (SSC), NorthernWaves, Primekey, Airforestry, Swedish Post and Telecom Authority (PTS), European Incoherent SCATter Scientific Association (EISCAT), Swedish Transport Administration, Swedish Forest Industries Federation, Region Norrbotten, Region Västerbotten, Region Stockholm, Eutelsat-OneWeb, Airbus, Viasat and Thales Alenia Space are also contributing to the work. The aim is to integrate traditional land-based mobile communications and space-based satellite communications into 6G, which is expected to be in use in the 2030s. The vision is that mobile communication services will be seamlessly available to anyone with a 6G device, anywhere, anytime. The focus will be on sustainability and energy efficiency, reliability and resilience, as well as system interoperability and always-on artificial intelligence. To achieve the vision, research will focus on improving hardware for both 6G devices and space-based satellites, developing signal processing methods that handle high signal losses and are robust to space-based interference, developing network technologies that integrate terrestrial and space systems, and developing new intelligent applications that combine communication, location and remote sensing. Job description We welcome an enthusiastic and adaptable postdoctoral researcher to join our interdisciplinary research group related to 6G satellite technologies and satellite constellations. The research will be carried out in collaboration with institutional and industrial partners within the multidisciplinary center of excellence and will use, among others, simulations, test facilities and nanosatellite platforms. As a postdoctoral researcher, you will be expected to perform both experimental and theoretical work within your research studies and to communicate your results at national and international conferences and in scientific journals. In addition, you will contribute to teaching courses given in the space systems subject at undergraduate and graduate level, supervising master students and PhD students, and working on grant applications to initiate new project-based research directions related to the research conducted in the space systems subject. The applicant is expected to participate in the group's joint development of the research and education area and to collaborate with research groups both within the department, the university and with other universities, colleges and other external parties, both nationally and internationally. Qualifications To be eligible for appointment as a postdoctoral research associate, the candidate must have a doctoral degree, or a foreign degree equivalent to a doctoral degree, in space technology, with a focus on small satellites. Priority should be given to the completion of the doctoral degree within a maximum of three years before the closing date for applications. The assessment is based on the candidate's research, teaching and industrial project potential. However, emphasis will be placed on the qualities that will enable the successful candidate to contribute to the future development of small satellite research at Luleå University of Technology, both in terms of research and education. Applicants should also have good communication skills in written and oral communication in English. Information to be provided This position is a full-time position for two years.
