CAIN-42 CAIN StudioCAIN Formal Verification & Proof Engineer
Express safety rules as solver queries, interpret SAT/UNSAT/UNKNOWN correctly, and attach proofs to AI-generated fixes.
Who it's for
Engineers who review or generate safety-critical code with AI assistance.
Why it's in demand
AI-written code is multiplying, and proofs that cover every input are the strongest answer to 'how do you know it is correct?'. Few engineers can use SMT solvers in practice. Sources →
