Key Responsibilities

Execute accurate data annotation for NLP (NER, sentiment, classification), computer vision (bounding boxes, polygons, segmentation), and content safety labeling. Perform RLHF tasks and prompt evaluation for large language models, ensuring annotation guidelines compliance and training data quality. Conduct QA reviews, resolve edge cases, document labeling rationale, and collaborate with leads on model performance improvement. Use Rex.zone tools to manage tasks, track quality metrics, and deliver production-ready datasets.

Required Qualifications

Detail-oriented, strong reading comprehension, and clear written communication. Familiarity with annotation tools and taxonomies, plus basic understanding of AI/ML workflows. Ability to follow precise instructions, meet deadlines, and maintain high inter-annotator agreement. Comfortable with content safety standards and privacy requirements. English proficiency required; additional languages are a plus.

Preferred Experience

Experience with RLHF, LLM evaluation, prompt engineering, named entity recognition, and computer vision annotation. Prior work in BPOs, annotation vendors, or AI labs. Knowledge of dataset curation, sampling strategies, and QA methodologies. Familiarity with accessibility labeling, speech/audio transcription, and multi-modal evaluation is advantageous.

Workflows and Tools

Participate in structured pipelines: task intake, calibration, annotation, QA evaluation, reconciliation, and delivery. Apply annotation guidelines and decision trees for consistent outputs. Use Rex.zone task management, quality dashboards, and reviewer workflows to improve throughput and accuracy. Support continuous feedback loops for model performance improvement and guideline iteration.

Employment Types & Modifiers

Remote roles available across full-time, part-time, contract, freelance, and temporary engagements. Openings range from entry-level to senior specialist. Projects span NLP, computer vision, content safety, LLM training, and multimodal datasets. Employers include AI labs, tech startups, BPOs, and annotation vendors.

Compensation & Growth

Rates vary by domain complexity and quality tier. Performance-based incentives reward annotation accuracy, consistency, and throughput. Senior contributors can progress to QA lead, guideline author, or domain specialist roles across RLHF, prompt evaluation, and enterprise datasets.

How to Apply

Create your profile on Rex.zone, highlight domain expertise (NLP, CV, content safety), and complete skill verifications. Submit to remote data labeling openings and RLHF evaluator projects. Qualified candidates will receive task invites, calibration tests, and onboarding to start contributing to AI/ML training workflows.

Remote Data Labeling Q&A

  • Q: What is RLHF in data labeling?

    RLHF uses human feedback to guide model behavior. Evaluators rank or rate LLM outputs and provide structured signals that improve model performance.

  • Q: Do I need prior AI experience?

    Not always. Entry-level roles focus on guideline compliance and QA routines. Senior roles require experience with LLM evaluation or complex CV/NLP labeling.

  • Q: Can I work freelance or contract?

    Yes. Rex.zone hosts freelance, contract, part-time, and full-time opportunities from AI labs, startups, BPOs, and annotation vendors.
