About this job
Are you a seasoned mathematician passionate about driving advancements in AI? With large-scale language models making rapid progress, ensuring their ability to handle complex proof-based reasoning hinges on robust mathematical training data. Leveraging your deep expertise, you can contribute to making AI systems more adept at understanding abstract concepts, logical reasoning, and the intricate structures of modern mathematics. Your insights will be crucial in shaping the future of AI.
We seek individuals with a profound understanding of pure mathematics, capable of exploring advanced topics in probability theory, measure theory, real and functional analysis, optimization, abstract algebra, and category theory. Additionally, we require a solid grasp of Lean 4, the proof assistant and programming language.
On a daily basis, you will craft and review intricate proofs, ensuring the mathematical reasoning is both correct and rigorous, and pinpointing any subtle conceptual or logical errors. You will also work closely with our team to develop and refine prompts, evaluation frameworks, and mathematical reasoning benchmarks, thereby enhancing the overall quality of our operations.
Ideal candidates will have a fluent command of Lean 4, a current or in-progress PhD in pure mathematics, or recent postdoc experience. You should be well-versed in essential topics like 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. Effective, metacognitive communication skills are also critical.
Ready to harness your Lean 4 proficiency and mathematical prowess to form the reasoning core of tomorrow’s AI? Apply now and play a pivotal role in educating the models that will support researchers, scientists, and engineers worldwide.
Our compensation range is $35 to $65 per hour, with the specific rate determined based on your experience, expertise, and geographic location. As a contractor, you will need to supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO are not included.
