Subject Matter Expert – Mathematics (Portuguese BR) – Remote

Role overview

Create and review realistic mathematics scenarios in Portuguese BR for an AI benchmarking project. The work is grounded in local or regional operating contexts and tests whether responses reflect professional practice rather than generic recall. Tasks combine domain judgment with language-specific context across applied mathematics, probability, statistics, computational methods, and mathematical physics. Contributors design the work, adapt scoring criteria, review responses, and produce defensible reference solutions.
