About AI Training Work

AI systems learn from examples created, reviewed, and evaluated by people. In this role, your quantitative finance expertise will help produce sophisticated text-based training and evaluation material that supports the development of advanced AI models.

AI training is a flexible way to work at the cutting edge of technology. Contributors use specialized knowledge to write examples, assess model outputs, and create reliable data for increasingly capable systems.

• Work with text generation, evaluation, rating, and fine-tuning content
• Apply advanced subject-matter knowledge to practical AI development
• Part-time, remote work that can fit around other commitments

The Role

OpenTrain AI is seeking an intermediate Financial Mathematics Expert to design and verify complex, research-style problem sets using Python. The problems should be relevant to quantitative finance and financial modeling, computationally intensive, and designed so they cannot be solved manually.

You will author original problems across areas such as stochastic processes, optimization, simulation, time series, and risk modeling. Every solution must be validated in Python and supported by clear, reproducible documentation.

• Role type: Part-time contractor
• Time requirement: 20+ hours per week
• Data type: Text
• Compensation: $15 to $60 per hour

What You'll Do

You will combine financial mathematics, quantitative modeling, and Python programming to create challenging material for AI training. The work requires careful problem design, technically sound solutions, and documentation that allows others to reproduce your results.

• Create original, complex problems in quantitative finance and financial modeling
• Develop computationally intensive tasks involving advanced methods
• Author problems involving stochastic processes, optimization, simulation, time series, and risk modeling
• Implement and validate solutions in Python
• Use clear, reproducible documentation for each solution
• Review or annotate text as part of the project workflow

Requirements

Applicants should have a strong foundation in financial mathematics or a related quantitative field, along with practical experience applying Python to finance, modeling, or numerical analysis. The role is intended for intermediate-level contributors.

• Bachelor’s degree or higher in finance, mathematics, statistics, or a related field
• At least 2 years of quantitative finance or modeling experience
• Strong Python skills with NumPy, SciPy, Pandas, SymPy, and statistics or machine learning libraries
• Experience with numerical methods and simulation
• Hands-on text annotation or review experience
• An international or applied project background is a plus
• Ability to provide an English CV and declare English proficiency
• Your CV should be in English and include your English proficiency level, email address, and phone number

Who Should Apply

This opportunity is suited to quantitative finance professionals, financial mathematicians, statisticians, and technically strong researchers who enjoy turning complex concepts into rigorous computational problems. It is especially relevant for applicants who can explain advanced methods clearly and verify results with reliable Python workflows.

• Quantitative finance and computational mathematics expertise
• Strong attention to mathematical accuracy and reproducibility
• Comfort creating original technical content rather than only solving existing exercises
• Availability for at least 20 hours per week
