What you'll do

• Design and implement multi-file coding tasks that simulate real-world scenarios across bug fixing, new feature development, refactoring initiatives, and migration projects.
• Author clear, detailed natural-language specifications accompanied by reference implementations that serve as the ground truth for evaluation.
• Develop and extend comprehensive unit and integration test suites using frameworks such as pytest, Jest, JUnit, xUnit, or Go testing to validate functionality and catch regressions.
• Conduct thorough peer reviews of generated tasks, assessing them for correctness, clarity, realism, and adherence to provided specifications.
• Identify edge cases, ambiguities, and potential failure modes within codebases and task definitions to improve robustness.
• Ensure strict alignment between natural language specifications, reference code, test artifacts, and expected outputs.
• Navigate and debug large, multi-file production codebases to create authentic engineering challenges.
• Apply refactoring techniques and manage production migration scenarios within the designed tasks.
• Collaborate asynchronously with other expert contributors to maintain a high bar for task quality and consistency.
• Translate complex technical requirements into structured, actionable evaluation assets for AI model benchmarking.

Requirements

• Advanced professional written proficiency in English to articulate complex technical specifications and review feedback.
• Three to seven years of professional software engineering experience in production environments.
• Strong proficiency in Python and JavaScript or TypeScript for primary development tasks.
• Working knowledge of at least one additional backend language such as Java, C#, or Go.
• Demonstrated backend or full-stack development experience building and maintaining production systems.
• Hands-on experience with major testing frameworks (e.g., pytest, Jest, JUnit, xUnit, Go testing) for test generation and validation.
• Proven ability to debug, navigate, and understand large, multi-file codebases independently.
• Solid track record of conducting code reviews, performing refactoring, and executing production migrations.

Nice to have

• Prior experience contributing to AI model evaluation, benchmarking, or red-teaming efforts.
• Familiarity with designing synthetic datasets or evaluation harnesses for code generation models.
• Experience with static analysis tools, linters, or automated code quality gates.
• Background in developer tooling, compiler design, or programming language implementation.
• Previous freelance, consulting, or project-based work managing own schedule and deliverables.
• Open-source contributions demonstrating code review and collaborative development practices.

Skills & tools

• Python, JavaScript, TypeScript, Java, C#, Go, pytest, Jest, JUnit, xUnit, Go testing, Git, Code Review, Refactoring, Production Migrations, Backend Development, Full-Stack Development, Technical Writing, Specification Design, Test Generation, AI Evaluation, Benchmarking.

Practical notes

• This is a 1099 independent contractor role; consultants are responsible for their own tax obligations, benefits, and equipment provisioning.
• Payment is structured on a per-project basis; the advertised hourly range ($45-$80 USD) reflects estimates based on anticipated completion time rather than guaranteed hourly wages.
• No visa sponsorship is provided; candidates must have valid work authorization for their country of residence (Mexico).
• The role is fully remote within Mexico with no office attendance required; contributors set their own hours to meet project deadlines.
• Simultaneous engagements with other employers or vendors are permitted, subject to those parties' policies.
• No relocation assistance or signing bonuses are offered for this project-based engagement.
• Candidates should be prepared to demonstrate coding proficiency and code review skills during the selection process.
