Computational Mathematics Researcher (Task Author)

Design original research-grade evaluation tasks based on your computational work. Each task should let AI models be evaluated on expert-level mathematics.

• Set the metrics for judging solutions without revealing the exact passing thresholds.
• Provide a reference solution and tests for each task.
• Revise tasks using structured review feedback until they are approved.
• Optionally review and calibrate tasks from other experts in your field.

What it pays and takes

• Pay: $100 per hour.
• Time: 20+ hours per week, with a flexible task-based schedule and no fixed weekly schedule.
• Location: Open to candidates in the listed countries; this role is not worldwide.
• Language: Fluent English.
• Education: Research-track bachelor's, master's, or PhD student, postdoc, or candidate in mathematics, applied mathematics, statistics, or a closely related field.
• Experience: Hands-on experience writing code, preferably in Python, to implement or validate mathematical methods; ability to turn computational research into a clear task with a reference solution and tests.
• Work independently and manage your own time.
• You must be able to work as an independent contractor without visa sponsorship. F-1 visa holders, including those on OPT or CPT, are not eligible.
• Preferred: Research in numerical methods, optimization, stochastic processes, computational topology, or number theory; public code, a thesis, or papers showing your computational work; or experience in data annotation, data labeling, or AI/ML evaluation.
