đź“‹ Description

  • • Design and implement multi-file coding tasks focused on bug resolution, feature implementation, refactoring, and test generation for AI training datasets.
  • • Write clear, precise natural-language specifications and reference implementations that accurately reflect real-world software engineering scenarios.
  • • Develop and extend comprehensive unit and integration test suites using frameworks such as pytest, Jest, JUnit, xUnit, or Go testing to validate code behavior.
  • • Review peer-generated coding tasks for correctness, clarity, realism, and alignment with specified requirements.
  • • Identify edge cases, ambiguities, logical inconsistencies, and potential failure modes in both task specifications and submitted solutions.
  • • Ensure strict alignment between task specifications, reference code implementations, and expected outputs across diverse programming contexts.
  • • Contribute to the creation of production-realistic coding challenges used to train and evaluate AI models in software engineering tasks.
  • • Participate in structured peer review processes to assess the quality and accuracy of submissions from other contributors.
  • • Navigate and debug large, complex, multi-file codebases to validate functionality and identify subtle defects.
  • • Perform code reviews and refactoring tasks to improve code quality, maintainability, and adherence to best practices.

  • • Maintain professional written proficiency in English to produce clear, unambiguous task descriptions and feedback.
  • • Deliver high-quality, validated artifacts including reference implementations, test suites, and structured peer review feedback.
  • • Work independently on project-based assignments with no direct supervision or team collaboration required during execution.

  • • Advanced professional written proficiency in English
  • • Strong proficiency in Python and JavaScript/TypeScript
  • • Backend or full-stack development experience in production systems
