Job summary

DataAnnotation is seeking contributors who can probe frontier models by vibe-coding real engineering tasks, fixing bugs, extending APIs, and shipping features, then evaluating how far the model can operate autonomously. You will document failures to teach next-gen coding agents, rate reasoning, and help improve safety by red-teaming.

Clear, precise written English is essential. This flexible, remote role offers competitive compensation, reflecting the impact of your analyses on cutting-edge AI

Qualifications

• Professional or serious open-source experience shipping production code.
• Excellent written English for documentation and explanations.
• No degree required; demonstrated ability matters.

Responsibilities

• Vibe-code with frontier models on real tasks: fix bugs, extend APIs, ship features.
• Analyze the AI's work against production standards and explain failures.

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.
