Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. 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 a total turnover of almost SEK 2.1 billion per year. We are currently 1,900 employees and have 18,700 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope you will help us build the sustainable businesses and communities of the future. Northern Sweden is a European space region with multiple stakeholders collaborating for the development of space technology and science in space. Luleå University of Technology (LTU) offers space research and teaching, the Institute of Space Physics (IRF) focuses on space plasma research and instrument development, and the EISCAT scientific organization performs radar observations of the upper atmosphere and ionosphere. The Swedish Space Corporation (SSC) with its facilities at Esrange provides services and infrastructure for access to space. 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 As part of the Space Sweden North project, you will join an academic team working in close collaboration with local and national industry to further develop Sweden's space sector in research, development and testing of space propulsion systems and their applications. Duties and responsibilities As a postdoctoral researcher, you will participate in research on space propulsion systems - in particular on solid fuel, hybrid fuel and liquid fuel systems. You will be involved in teaching undergraduate and graduate courses in space systems, supervising master and PhD students, and working on grant applications to initiate new project-based research directions related to the research conducted in space systems. 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, applicants must have a PhD or equivalent foreign degree in space science or another discipline, with a primary focus on rocket propulsion systems (liquid fuel or hybrid engines). Preference will be given to those who have completed a PhD no more than three years before the application deadline. Evaluation is based on the applicant's research, teaching, and industrial projects. Emphasis shall be given to the qualities that are applicable to contribute to the future development of rocket propulsion systems at Luleå University of Technology, regarding both research and teaching. Applicants should have good communication skills. You must be able to express yourself in English, at an advanced level, in writing and orally to present and publish research results internationally.
