Data Labeler
About us
White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems. At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn’t do. We automatically test, enforce, and continuously improve these policies at scale.
We’ve raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others
We process over one hundred million API calls every month
We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model
We’re a small, highly focused team. If you want to work deeply on hard problems, see your work ship to production quickly, and influence how AI safety is actually built – you’re the one we need.
In this role, you will
Review and evaluate AI conversations and model outputs
Assess responses for safety, quality, accuracy, policy compliance, and user intent
Identify harmful, unsafe, misleading, or low-quality behavior
Label and categorize model outputs according to internal evaluation frameworks
Moderate sensitive content and identify policy violations
Compare, rank, and score model responses
Investigate edge cases and ambiguous situations
Provide structured feedback to researchers and engineers
Help improve evaluation guidelines and annotation processes
Contribute to the datasets used to train and evaluate AI systems
We're looking for someone who
Has exceptional attention to detail
Can make consistent decisions across large volumes of data
Enjoys analysing nuanced situations where there isn't always a clear answer
Can follow guidelines while exercising good judgment
Has strong written English skills
Communicates clearly and explains reasoning well
Is curious about AI and how these systems work
You might be a great fit if you
Have experience with content moderation, trust & safety, quality assurance, compliance, or policy enforcement
Have experience in data annotation, AI evaluation, RLHF, or model assessment
Have worked with AI tools extensively and understand their strengths and limitations
Enjoy finding edge cases and unusual model behavior
Important note
This role may involve reviewing content that is offensive, harmful, violent, sexual, or otherwise disturbing. We provide tooling, and support, but candidates should be comfortable working with sensitive content when necessary
