Operations Research & Applied Mathematics Specialist

You will create technically demanding problems for AI training and evaluation. Your work will use operations research, applied mathematics, optimization, modeling, and practical examples from real operational systems.

The problems should be technically credible, accurate, clear, and well documented. You will work independently, manage your own time, and use practical judgment rather than relying only on theoretical examples.

• Write research-level problems in operations research, applied mathematics, or a related field.
• Develop scenarios using real operational data and modeled systems.
• Create work grounded in areas such as supply chains, scheduling, and physical processes.
• Keep technical writing accurate, clear, and well documented.
• Complete assignments independently and manage your own time.

About AI training work

AI training work is the human work behind systems that learn from examples. Specialists create and review problems, text, code, and other data so AI models can produce more useful and accurate results.

People with strong technical experience are paid to bring real-world judgment and subject knowledge to this process, especially when the work requires credible modeling, optimization, or applied mathematics.
