Pure Mathematics Specialist – Freelance AI Trainer Project in London

Are you a theoretical mathematics expert eager to shape the future of AI? Large-scale language models are rapidly advancing, and their ability to handle rigorous proof-based reasoning depends on high-quality mathematical training data. With your advanced expertise, tomorrow's AI can better understand abstraction, logic, measure theory, homotopy, and the deep structures of modern mathematics. That training data begins with you—your theoretical insight will help power the next generation of AI.

We're looking for specialists with deep foundations in pure mathematics who can engage with advanced topics across probability theory, measure theory, real and functional analysis, optimization, abstract algebra, and category theory. You'll challenge cutting-edge AI systems with complex proofs, evaluate mathematical reasoning for correctness and rigor, and identify subtle conceptual or logical failures that only trained mathematicians can catch.

On a typical day, you will converse with the model on theoretical problems, construct and evaluate proofs, analyze reasoning steps for validity, articulate failure modes, and collaborate with our team to refine prompts, evaluation frameworks, and mathematical reasoning benchmarks.

Candidates with a freshly earned PhD or current PostDoc experience in pure mathematics are ideal. A strong command of core areas is required, and applicants should be comfortable with topics such as Markov's and Chebyshev's inequalities, Hoeffding bounds, convergence theorems, the Carathéodory extension theorem, the Riesz representation theorem, Banach–Alaoglu, Lax–Milgram, stochastic approximation, Van Kampen's theorem, the Yoneda embedding, and representability in cohomology. Clear, metacognitive communication—explicitly articulating reasoning and proof strategies—is essential.

Ready to turn your pure math expertise into the reasoning backbone of tomorrow's AI? Apply today and help teach the model that will support researchers, scientists, and engineers around the world.

We offer a pay range of $6 to $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you'll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
