  • Location: Open to candidates in the United States.
  • Education: A PhD in pure or applied mathematics is listed; applicants with depth in at least two core qualification areas are also encouraged to apply.
  • Expertise: Demonstrated depth in proof and formal methods, symbolic computation, optimization, numerical analysis, or a field such as algebra, topology, geometry, number theory, analysis, or combinatorics.
  • Skills: Strong written communication, attention to detail, and the ability to explain complex mathematical ideas clearly.
