Full Job Description

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 code solutions.
  • • Ensure strict alignment between task specifications, reference implementations, and expected outputs across diverse programming contexts.
  • • Work within large, complex codebases to simulate production-grade software engineering challenges for AI model training and evaluation.
  • • Participate in code reviews and contribute to refactoring efforts that improve code quality, maintainability, and scalability.
  • • Execute production migrations and debugging tasks that mirror real-world technical debt and system evolution scenarios.
  • • Operate as an independent contractor with full control over schedule, tools, and workflow while delivering high-quality project outputs.
  • • Contribute to a project-based, part-time engagement with no expectation of long-term employment or fixed hours.
  • • Collaborate remotely with an AI lab and other expert contributors to generate training data that improves AI systems’ coding capabilities.
  • • Maintain professional written proficiency in English to produce unambiguous specifications, feedback, and documentation.
  • • Deliver structured, actionable peer review feedback that helps refine the quality and realism of coding tasks submitted by other contributors.
  • • Generate validation artifacts including test coverage reports, expected outputs, and failure case analyses to support AI model evaluation.
  • • Work independently with minimal supervision while adhering to project guidelines and quality standards.
  • • Simultaneously provide services to other vendors or employers, provided such arrangements do not conflict with project requirements or confidentiality obligations.

🎯 Requirements

  • • Advanced professional written proficiency in English
  • • 3–7 years of professional software engineering experience
  • • Strong proficiency in Python and JavaScript/TypeScript; working knowledge of Java, C#, or Go
  • • Backend or full-stack development experience in production systems
  • • Experience with testing frameworks (e.g., pytest, Jest, JUnit, xUnit, Go testing)
  • • Proven ability to debug and navigate large, multi-file codebases

🏖️ Benefits

  • • Project-based compensation paid per task with flexible, self-determined scheduling
  • • Ability to work remotely with full autonomy over tools and workflow
  • • Opportunity to contribute to cutting-edge AI training datasets without long-term commitment
  • • Potential to work alongside other expert contributors and leading AI labs
