DataAnnotation is seeking contributors to help validate and improve AI coding agents. You’ll vibe-code with frontier models on real tasks, fix bugs, extend APIs, and ship features while watching how far the model can go on its own.

You’ll analyze the AI's work against production standards, identify bugs, explain failures, and rate the model’s reasoning. You’ll also red-team the models to uncover unsafe code and confidently wrong solutions before real users hit them.

Qualifications

• Professional or serious open-source experience shipping production code.
• Clear written English: your explanations are the training signal.

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.
