What we look for in a successful Researcher:

  • Enthusiasm for designing correct-by-construction protocols, disseminating knowledge, and advancing correctness awareness within the ecosystem.
  • Graduate work and/or academic quality publications in a relevant field, eg. distributed systems, algorithmic game theory, formal verification, mathematical logic, etc.
  • A deep understanding of computer science and formal logic fundamentals (first-order logic, temporal logic, Satisfiability Modulo Theories, etc.).
  • Experience with formal verification approaches (theorem proving, model checking, static analysis, runtime verification, etc.).
  • Significant experience with technical writing in English (e.g. research papers, specifications, design documents, documentation, etc.).
  • The ability to take ownership and see initiatives through.
