Job summary

DataAnnotation is seeking contributors to evaluate and validate AI-model code through hands-on coding sessions. You will analyze model outputs, identify bugs, and document failures to drive improvements in future agents.

Join a flexible, remote team while you work on real engineering tasks, explain your reasoning clearly, and help push the boundaries of autonomous coding systems.

Qualifications

• Open-source production coding experience is required.
• Clear written English is essential.
• No degree required; focus on what you can do.

Responsibilities

• Vibe-code with frontier models on real tasks: fix a bug, extend an API, ship a feature, and test how far the model goes.
• Analyze the AI's work against production standards: find bugs, explain failures, and rate reasoning.
• Red-team the models to expose unsafe code and confidently wrong solutions before real users see them.

Job description

The newest models can vibe-code a whole feature in minutes. Someone has to check whether that code actually works, and that someone is you.

You'll run agentic coding sessions on real engineering tasks, analyze what the models produce, and red-team them until they fail in interesting ways. Every failure you document teaches the next generation of coding agents.

What you’ll actually do

• Vibe-code with frontier models on real tasks: fix a bug, extend an API, ship a feature, and see how far the model gets on its own.
• Analyze the AI's work against production standards: find the bugs, explain the failure, and rate the model's reasoning.
• Red-team the models to expose unsafe code, faked test passes, and confidently wrong solutions before real users hit them.

What we look for

• Professional or serious open-source experience shipping production code.
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.

Compensation

Up to $150+/hr depending on task difficulty and specialization. Many contributors add $100k–$200k a year; some make it their full-time income.
