Data Annotation Jobs — Work From Home

Data annotation specialist is a recognized AI/ML job entity focused on labeling and evaluating training data for LLMs and models. On Rex.zone, you’ll contribute to real RLHF pipelines, prompt evaluation, content safety labeling, named entity recognition, computer vision annotation, and QA reviews that improve model performance. Apply to remote, contract, freelance, and full-time roles across AI labs, tech startups, BPOs, and annotation vendors.

Key Responsibilities

Create high-quality labels across NLP, computer vision, audio, and multimodal datasets. Execute RLHF tasks including ranking completions and reviewing assistant outputs. Perform prompt evaluation, red teaming, and content safety labeling. Follow annotation guidelines and contribute to QA evaluation cycles. Tag entities (NER), intents, sentiments, and attributes; draw bounding boxes, polygons, masks, and keypoints. Document edge cases, improve label taxonomies, and collaborate in LLM training pipelines to drive model performance improvement.

Required Qualifications

Strong attention to detail and consistency in following annotation guidelines. Familiarity with data labeling tools and JSON/CSV formats. Ability to assess training data quality and provide clear feedback. Comfortable with LLM evaluation tasks, safety policies, and bias checks. Excellent written communication and time management for remote work. Entry-level applicants welcome; senior reviewers should have demonstrated QA leadership.

Workflows & Tools

Work within structured annotation queues linked to LLM training pipelines. Use web-based tools for NER, classification, and computer vision annotation (bounding boxes, segmentation). Participate in double-blind reviews, inter-annotator agreement checks, and guideline updates. Track quality via precision/recall, agreement scores, and error taxonomy. Provide notes for model fine-tuning, reinforcement learning from human feedback (RLHF), and red-teaming reports.

Role Types & Modifiers

Remote roles with options: contract, freelance, full-time, part-time, entry-level, and senior reviewer. Opportunities across NLP, computer vision, content safety, speech, and multimodal datasets. Employers include AI labs, tech startups, BPOs, and specialized annotation vendors.

Success Metrics & Impact

Maintain high training data quality, annotation guidelines compliance, and consistent QA scores. Contribute measurable improvements to model performance, reduce error rates, and increase large language model evaluation reliability. Feed actionable insights back into data collection, labeling criteria, and model fine-tuning loops.

Compensation & Growth

Rates vary by domain complexity and seniority. Entry-level tasks pay per item or hour; senior QA reviewers earn premiums for guideline audits and quality leadership. Grow into lead annotator, QA specialist, or evaluation program manager roles.

How to Apply

Create your profile on Rex.zone, select domains (NLP, CV, content safety), complete sample tasks to calibrate guidelines compliance, and opt into remote work queues. Qualified applicants receive project invitations based on past metrics and availability.

Frequently Asked Questions

Q: What is RLHF in annotation work?
RLHF (Reinforcement Learning from Human Feedback) involves ranking and reviewing model outputs to guide policy and reward models; annotators help produce the feedback signals used for fine-tuning.
Q: Do you offer senior reviewer roles?
Yes. Senior roles lead QA evaluation, guideline authorship, and complex domains like content safety and multimodal LLM evaluation.
Q: Can I work globally?
Yes. Rex.zone offers remote, global opportunities; some projects may require language or regional expertise.
