Responsibilities

• Generate prompts that challenge the AI and push its limits.
• Define comprehensive scoring criteria to evaluate the accuracy of the AI’s answers.

• Create new training prompts and refine model responses to shape the future of AI.

Requirements

• At least 3 years of professional experience with Ruby and key ecosystem tools (RSpec, Bundler).
• Advanced English proficiency (C1) or higher.
• Comfortable with Git and standard Linux CLI tools.
• Hands‑on experience with containerization (Docker) and CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins).
• Deep understanding of testing principles, test‑driven development, debugging, profiling, and code optimization.

Desirable

• Contributions to open‑source Ruby projects (pull requests, code reviews, issue tracking).
• Experience with large monorepositories or major open‑source projects.
• Experience with automated benchmarking, scripting, or infrastructure‑as‑code tools.
• Experience working with AI‑generated code or code evaluation projects.

Soft Skills

• Analytical and detail‑oriented mindset: proactively identifies bugs, edge cases, and test coverage gaps.
• Concise and structured communication, both in documentation and asynchronous team discussions.
• Strong ownership: able to drive tasks end‑to‑end, propose improvements, and promptly flag risks or blockers.
• Adaptability and resilience: thrives in fast‑changing requirements and ambiguous project contexts.
• Team player: open to code reviews, feedback, and knowledge sharing.
• Ready to learn new methods, switch between tasks and topics quickly, and handle challenging, complex guidelines.

Benefits

• Pay up to $60/hour depending on skills, experience, and project needs.
• Part‑time, remote freelance project that fits around your primary professional or academic commitments.
• Work on advanced AI projects and gain valuable experience that enhances your portfolio.
• Influence how future AI models understand and communicate in your field of expertise.
