The work
You will create technically demanding problems for AI training in operations research, applied mathematics, or a related field. Your work should reflect real operational systems and practical use cases such as supply chains, scheduling, and physical processes.
You will use real operational data and modeled systems to build credible scenarios. You will also keep your work accurate, clear, and well documented while managing assignments independently.
- Write research-level problems in operations research, applied mathematics, or a related field.
- Create scenarios grounded in optimization, modeling, and real operational systems.
- Use your own real operational data with Python or a similar programming language.
- Apply practical judgment instead of relying only on theoretical examples.
- Write clearly about technical work and document your reasoning.
- Manage your own time and complete assignments independently.
