This three-year, full-time research position focuses on the philosophical and formal analysis of reflection principles, a foundational concept in epistemology, philosophy of science, and the foundations of mathematics. The project aims to develop a unified framework for understanding proof-theoretic, set-theoretic, and probabilistic reflection principles, which are central to debates about soundness, mathematical truth, and rational credence.

Proficiency in English at C1 or C2 level is required. The PhD must be from an institution other than the University of Warsaw, or the candidate must have completed a substantial postdoctoral fellowship abroad. Additional advantages include international research experience, academic awards, and science popularization activities. The university does not provide housing.

The position offers an annual gross salary of PLN 140,000 (approx. PLN 8,900/month gross), plus a 13th month remuneration, funding for conferences, seminars, academic literature, and a work laptop.
