Mathematicians

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.

Responsibilities

• 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.

Requirements

• 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.

Why Join

• 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.

• 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.
