  • Support SWE Bench-style evaluation tasks with structured and unstructured datasets.
  • Design, build, and validate data pipelines for benchmarking and evaluation workflows.
  • Process and analyze data, prepare features, and validate data science workflows.
  • Write, run, and modify Python code for data processing and local experiments.
  • Check data quality, transformations, and outputs for correctness and reproducibility.
  • Create clean, documented, reusable workflows suitable for benchmarking.
  • Take part in code reviews focused on code quality and maintainability.
  • Work with researchers and engineers to develop real-world data engineering and data science tasks for AI systems.
