Mathematicians

Join to apply for the Mathematicians role at Mercor
.

Mercor is hiring mathematicians on behalf of a leading AI Lab developing advanced agents AI systems capable of complex reasoning, planning, and autonomous problem‑solving. This is a unique opportunity to work directly with world‑class AI researchers and engineers, contributing the mathematical foundations that power next‑generation intelligent agents.

• Develop rigorous mathematical tasks, proofs, and structured reasoning datasets used to train and evaluate agentic AI models.
• Analyze model reasoning steps to identify logical weaknesses, conceptual gaps, and opportunities for improved mathematical understanding.
• Collaborate closely with research teams to design multi‑step problem‑solving pipelines, evaluation benchmarks, and reasoning curricula.
• Create high‑quality annotations, explanations, and walkthroughs that teach models how to solve mathematical problems step‑by‑step.
• Support model training efforts by constructing mathematical tests for generalisation, abstraction, deductive reasoning, and symbolic manipulation.
• Work with engineers to integrate mathematical constraints, verification tools, and logic‑based checks into agent workflows.
• Participate in synchronous collaboration sessions (4‑hour windows, 2–3 times per week) to refine reasoning approaches, review agent outputs, and iterate on dataset improvements.

• Strong background in Mathematics, Applied Mathematics, Theoretical Computer Science, or a closely related quantitative discipline.
• Deep understanding of core mathematical fields: algebra, calculus, probability, combinatorics, optimization, logic, or number theory.
• Demonstrated problem‑solving ability through research, olympiads/competitions, teaching, or advanced coursework.
• Ability to break complex problems into clear, structured steps suitable for model learning and reasoning supervision.
• Familiarity with AI reasoning models, LLMs, or agentic AI concepts is a strong plus.
• Comfort working with Python for inspecting model outputs, running experiments, or generating mathematical datasets.
• Excellent collaboration and communication skills.
• Ability to commit 20–30 hours per week, including required synchronous collaboration sessions.

• Work directly with a world‑class AI research lab building the reasoning capabilities behind tomorrow’s autonomous agent ecosystems.
• Influence how advanced AI systems learn mathematics, apply logic, and develop reliable multi‑step reasoning abilities.
• Enjoy schedule flexibility — select your own 4‑hour collaboration windows and manage your 20–30 hour work week.
• Be engaged as an hourly contractor through Mercor, giving you autonomy while contributing to mission‑critical agent reasoning projects.
• Collaborate with top mathematicians, researchers, and AI developers working at the intersection of formal reasoning and advanced intelligence.
• Join a global network of technical experts shaping how the next generation of AI agents think, solve problems, and evolve at scale.
