Fintech and Crypto Expert

In this hourly, remote contractor role, you will work as a Fintech / Crypto Subject Matter Expert (SME) to review AI-generated fintech, payments, and crypto/Web3 responses and/or create expert content, evaluating reasoning quality and step-by-step problem-solving while providing precise written feedback. You will assess solutions for accuracy, clarity, safety, and adherence to the prompt; identify errors in financial product logic, payments flows, blockchain/crypto concepts, custody and key management, smart-contract risk reasoning (conceptual), fraud/AML considerations, and regulatory-compliance awareness; fact-check technical and market concepts; write high-quality explanations and model solutions that demonstrate correct reasoning; and rate and compare multiple responses based on correctness and reasoning quality. This role is with SME Careers, a fast-growing AI Data Services company and subsidiary of SuperAnnotate, delivering training data for many of the world’s largest AI companies and foundation-model labs.

Important: There is no immediate project for this role; however, if qualified, you will be among the first experts we reach out to when relevant opportunities arise. This will also provide you with access to future projects available through our expert network.
