This remote contract role asks domain experts with graduate-level training to write hard machine learning evaluation problems that test how advanced AI systems reason. Specialists also judge AI-generated solutions for correctness, creativity and methodological rigor, and they document difficulty and likely failure modes. It suits researchers whose deep, niche expertise goes beyond standard ML knowledge.
This remote freelance role asks Portuguese speakers to review AI-generated Portuguese translations and original text for accuracy, naturalness and cultural fit. Reviewers flag mistranslations and register problems, propose more idiomatic wording, and give structured feedback on quality. It suits people with native or near-native Portuguese who work independently and communicate well in English.
This remote, part-time freelance role asks Portuguese speakers to review text produced by AI systems and content written in Portuguese. The work centers on judging whether the language is accurate, natural, and culturally suited to its audience. It suits people with deep knowledge of Brazilian or European Portuguese who can give structured, independent feedback.
This contract role centers on building the Python infrastructure that AI labs use to prepare and assess training data, including data pipelines, annotation tools and evaluation systems. It is aimed at senior engineers with deep production Python experience who can design distributed systems and lead architecture decisions.
