The University of Warsaw, Faculty of Physics, Institute of Geophysics, invites applications for two positions as Assistant Professor / Post-Doc in the MAESTRO-14 project, "Free-form optical fibers for information systems." The successful candidates will engage in the design and modeling of advanced optical fibers, contribute to the development of new numerical methods for modeling special free-form fibers, and conduct both experimental and numerical studies of phenomena in these fibers. The research will also involve developing and testing new types of optical fibers for applications in telecommunications, lasers, and sensors. The position offers the opportunity to collaborate with a dynamic technology team, young scientists, and students, and to publish research results in reputable scientific journals. Participation in seminars, conferences, and training courses is expected. Employment is temporary and full-time, in accordance with National Science Centre (NCN) regulations, and will last for at least six months. Applicants must hold a PhD in science or engineering (preferably in physics, mathematics, electronics, or computer science), with the degree obtained no earlier than seven years before the year of employment (extensions possible for parental or medical leave). Candidates should have experience in theoretical or experimental research involving passive, active, specialty, or telecommunication optical fibers, or in modeling linear and nonlinear phenomena, including the use of deep learning methods. Experience in research teams, dissemination of results, and proficiency in MATLAB, Python, PyTorch, or TensorFlow is required. Fluent English is essential. For Assistant Professor applicants, significant scientific achievements, a research plan, and international experience are required. Additional eligibility criteria are set by the NCN and University of Warsaw statutes, including restrictions on prior employment and supervision relationships. The selection process is based on scientific achievements, research experience, and competence for the project tasks. Applications should include a personal questionnaire, a description of research plans and achievements, proof of doctoral degree or planned date, and two letters of recommendation sent directly to Professor Ryszard Buczynski. The application deadline is January 30, 2026. The recruitment process is open, transparent, and merit-based, and selected candidates may be invited for an interview.

The appointee will also publish in high-impact journals, contribute to technology transfer, participate in the scientific life of the Centre, and help train early-career researchers. This is a full-time temporary post in Warsaw, Poland, at the Centre of Excellence for Structured Fiber Optics and Applications, ul. Pasteura 5, with employment expected to run until 31 December 2029. The announced remuneration is PLN 420,000 gross-gross per year, under the FNP regulations for team leaders. The project also provides funding for at least one doctoral candidate or early-career postdoctoral researcher until 31 December 2029, together with technical support for the team. Applicants should hold a PhD in science or engineering, preferably in physics, chemistry, mathematics, or technical sciences such as electronics, materials engineering, or computer science. Strong experience in passive, active, or specialty optical fibers, optical-fiber phenomena, optical glass synthesis, specialty fiber fabrication, or related linear/nonlinear modelling is expected. The post also requires a substantial research record, international or industry-facing team experience, demonstrable leadership potential, experimental research independence, familiarity with MATLAB, LabVIEW, or Python (or relevant fabrication/metrology expertise), and fluent spoken and written English. The position is part of a structured recruitment process with applications due on 20 September 2026 . Candidates should submit the required documents by email, including a personal questionnaire, research plan and interests, a summary of the most important scientific achievement, and proof of doctoral degree. Two recommendation letters must be sent directly by referees. Shortlisted candidates may be invited for an online interview, and the final decision will follow the University of Warsaw’s open and merit-based recruitment policy. This opportunity is especially relevant for researchers in optics, photonics, fiber sensing, and advanced optical materials who want to lead a team at a major European university and contribute to structured fiber-optics research with application and commercialization potential.

Research Assistant Professor / Post-Doc / Team Leader No. 4 in Mid-IR fiber optics is available at the University of Warsaw within the Centre of Excellence for Structured Fiber Optics and Applications. The successful candidate will work on developing new optical fibers for transmission, light generation, and sensing in the mid-infrared range. The project focus includes engineered optical properties through nanostructuring, fiber lasers emitting in the 2.5–5 µm range, and fabrication of ARF optical fibers from fluoride glasses. In addition to research and publication, the role includes contributing to technology transfer, participating actively in the scientific life of the Centre, and training early-career researchers. The appointment is part of the MAB FENG project and is linked to a team-lead position. The project provides funding for at least one doctoral candidate or early-career postdoctoral researcher until 31 December 2029, together with technical support for the team. The employment is temporary and full-time, based in Warsaw, Poland. Applicants are expected to hold a PhD or equivalent and have a strong track record in optics or related fields, especially in passive, active, or specialty optical fibers, optical glass synthesis, fiber fabrication, or modeling of linear and nonlinear phenomena.
