This freelance contract is for PhD-level mathematicians who will evaluate and improve how AI systems handle mathematical reasoning. The work covers writing and reviewing advanced problems, checking AI-generated proofs and calculations, and organizing mathematical content for training datasets. It suits holders of a doctorate in mathematics or a closely related field who can work independently and remotely on their own schedule.
This contract role asks mathematicians to formalize advanced theorems and proofs in Lean 4 and to audit existing formal proofs for correctness. The work also helps train language models to reason mathematically and feeds into large formal libraries such as mathlib. It suits people with graduate training in mathematics who are comfortable working independently and asynchronously.
This freelance role asks mathematicians to turn informal proofs into machine-checkable formal proofs in Lean 4, helping shape how advanced AI systems reason. The work covers theorems from many mathematical fields, contributions to large formal libraries, and auditing existing proofs. It suits holders of advanced mathematics degrees who can work independently on flexible, remote schedules.
This contract role asks mathematicians to write, solve and check advanced problems that help AI models reason more reliably in mathematics. It suits people with a Master's or PhD in mathematics or a closely related field who can work remotely and set their own schedule.
This remote, hourly contract role asks mathematicians with a Master's or PhD to write, solve and review advanced problems, and to evaluate the mathematical reasoning produced by AI models. It suits researchers who are strong in algebra, calculus, statistics or discrete mathematics and who can work independently on their own schedule.
The job consists of creating, solving and reviewing advanced mathematical problems so that AI models can reason more accurately. It is aimed at people with a Master's or PhD in mathematics or a closely related field who can work remotely and set their own schedule. No prior AI experience is required, but strong mathematical depth and rigor are essential.
This freelance remote role asks conservation and environmental science professionals to check how AI systems handle questions about ecosystems, land use, soil, water and biodiversity. The reviewer judges whether the scientific content and recommendations match sound practice, then gives structured, actionable feedback to improve the model's reasoning. It suits experienced practitioners who want to shape AI reliability while working on their own schedule.
This contract role asks physicists with a PhD to judge and improve the physics material used to train advanced AI systems. The work covers writing hard problems, checking AI-generated solutions for errors, and labeling concepts so models learn the structure of the field. It suits remote experts who can work independently and do not need prior AI experience.
This contract role asks a physics specialist to label and organize physics material used to train AI models. The work includes reviewing AI-generated solutions to physics problems and helping build training datasets across topics and difficulty levels. It suits candidates with research, teaching or applied problem-solving experience in physics.
This is a remote, hourly contract role for physicists who want to help AI models reason through hard science problems. The work centers on writing challenging physics problems with worked solutions and on checking how AI systems handle them, from undergraduate to PhD level. No prior AI background is needed, only strong physics knowledge and clear written communication.
This is a remote, hourly contract for physics graduates and current Masters students who want to help train and evaluate advanced AI models. The work is writing physics problems, solving them step by step, and judging whether AI-generated answers are scientifically accurate and well reasoned.
This remote contract asks a physics expert to write advanced problems that test how well AI models reason, along with clear step-by-step solutions. The work also includes checking AI-generated answers for accuracy and quality of reasoning, and helping researchers refine benchmarks. It is aimed at people holding a master's degree in physics or a related field, and no prior AI experience is needed.
This freelance contract role asks physics specialists to design hard problems and write clear step-by-step solutions that help train AI models. The work also includes checking AI-generated answers for scientific accuracy and quality of reasoning. It suits physicists with a master's-level background who can work independently and asynchronously.
This contract role asks economists to review and grade the economic reasoning in content drafted by AI systems, with a focus on regulation, welfare, taxation and public programs. It suits professionals with a background in public or applied economics who can give precise, written feedback on arguments and policy conclusions while working independently on task-based assignments.
This contract role asks mathematicians to turn informal proofs into machine-checkable Lean 4 code, helping AI systems learn to reason about formal mathematics. It suits researchers with strong proof-writing backgrounds who enjoy structuring arguments for proof assistants and examining where automated provers fail.
This contract role asks specialists to write and review advanced materials science problems and to check how AI models reason about them. It is aimed at people with a master's or doctoral degree in materials science or a closely related field, who know semiconductor materials or molecular modeling well. The work is remote and done independently, on a flexible schedule.
This remote freelance role asks soil and water specialists to check AI-generated scenarios on erosion control, watershed management, and conservation planning. Reviewers flag flawed assumptions and outdated methods, then write structured feedback so the AI's answers become more accurate and practical. It is aimed at scientists with several years of hands-on experience who can work independently on task-based assignments.
This remote, asynchronous role involves labeling and organizing statistical content, such as equations, datasets and problems, to build training data for AI systems. It also includes reviewing AI-generated statistics solutions, writing instructional material and testing models for reasoning errors and bias. It is aimed at people with strong probability and statistics backgrounds from research, teaching or applied work.
This remote, task-based role asks scientists to check AI-generated material on wildlife and habitat conservation for accuracy and ecological soundness. Reviewers judge the quality of the reasoning behind proposed conservation strategies and give structured feedback so the AI describes these topics correctly. It suits experienced ecologists and wildlife specialists who can work independently on a flexible schedule.
