The Work

You will create, solve, review, and validate challenging software-engineering tasks used to train AI systems. The work covers front-end and back-end systems, unfamiliar repositories, complex debugging, code translation, testing, and review of AI-generated patches.

You will work across interfaces, services, libraries, APIs, databases, and external dependencies. You will also assess whether proposed code is correct, complete, secure, and maintainable.

  • Explore and understand unfamiliar open-source software repositories.
  • Implement and debug front-end and back-end components.
  • Trace data and program execution across connected systems and external dependencies.
  • Reproduce software issues, identify their underlying causes, and implement fixes that fit existing architectures and contribution standards.
  • Translate complete coding builds from one programming language into another.
  • Write unit, integration, regression, and end-to-end tests.
  • Review AI-generated patches for correctness, completeness, security, and maintainability.

What It Pays and Takes

This is a fully remote contractor role with flexible scheduling. The work is listed as part time and is open to candidates in a defined set of countries across the Americas, Europe, Asia, Africa, and the Middle East.

  • $100 to $150 per hour equivalent, paid per task that meets the project specifications.
  • Expected commitment: approximately 15 hours per week.
  • Flexible scheduling, including the option to work weekends when needed.
  • Fluent English.
  • A public or otherwise verifiable GitHub profile.
  • Meaningful ownership of or contributions to one or more open-source repositories.
  • Strong software-engineering experience in front-end, back-end, full-stack, systems, developer tooling, infrastructure, or another substantial technical area.
  • Experience with multiple programming languages, such as TypeScript, JavaScript, Python, Java, Go, Rust, C++, C#, or Ruby.
  • Ability to understand and modify unfamiliar codebases.
  • A portfolio showing substantive authored code, not only documentation updates, dependency changes, formatting work, or minor corrections.
