Mechanical Engineering Expert

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Mechanical Engineering Expert based in Brazil. This is an opportunity for an experienced mechanical engineer to contribute directly to the development of high-quality training and evaluation data for cutting-edge AI models. You will design rigorous, original engineering problems that challenge advanced systems to demonstrate genuine technical reasoning. Your work will span areas such as mechanics, thermodynamics, fluid mechanics, heat transfer, dynamics, and mechanical systems. Each problem will need to be deterministic, technically precise, and supported by a complete, independently verifiable solution. You will combine engineering expertise, quantitative reasoning, and computational tools to validate complex problems and their expected answers. The role is highly focused and flexible, offering remote work on a part-time basis with an immediate start. It is particularly well suited to someone who enjoys challenging technical problems and wants to help shape the future of AI through expert-level engineering knowledge.
