Key Responsibilities

Produce high-quality annotations across text, image, video, and audio following detailed annotation guidelines. Execute RLHF comparisons and preference rankings to improve large language model evaluation. Perform prompt evaluation, red-teaming, and content safety labeling to uphold platform policies. Conduct named entity recognition, sentiment tagging, intent classification, and taxonomy mapping. In computer vision, create bounding boxes, polygons, keypoints, and segmentation masks. Participate in multi-stage QA evaluation, resolve conflicts, and document edge cases to drive model performance improvement and training data quality.

Required Qualifications

Proven attention to detail and consistency in annotation guidelines compliance. Ability to follow written instructions, escalate ambiguities, and meet SLAs. Familiarity with NLP tasks (NER, summarization, classification) or computer vision annotation. Comfortable with productivity targets and quality benchmarks (inter-annotator agreement, precision/recall). Strong written English; additional languages are a plus for multilingual datasets. Reliable internet, privacy-conscious workspace, and willingness to sign NDAs.

Preferred Experience

Experience with RLHF pipelines, LLM prompt engineering, or model-assisted labeling. Background in linguistics, data quality, content moderation, or safety policy. Prior work with annotation vendors, BPOs, AI labs, or tech startups. Familiarity with Python, regex, or basic scripting for dataset triage. Understanding of bias, fairness, and safety considerations in AI training.

Domains and Workflows

NLP: entity extraction, intent detection, summarization quality, dialogue safety, prompt evaluation. Computer Vision: object detection, instance/semantic segmentation, OCR QA. Content Safety: policy taxonomy mapping, severity calibration, age-appropriateness. LLM Training: preference ranking, chain-of-thought redaction checks, evaluation set curation, model performance tracking.

Employment Types and Schedules

Remote roles available as full-time, part-time, contract, freelance, and temporary projects. Opportunities for entry-level labelers, experienced annotators, and senior QA leads. Flexible time zones with core-hour windows for synchronous reviews when required.

Tools and Platforms

Use Rex.zone’s secure annotation workspace and integrated QA dashboards. Projects may leverage model-assisted labeling, ontology editors, prompt testing sandboxes, and audit trails. You may interface with third-party tools as needed (CV annotation suites, translation utilities), while all submissions and KPIs remain centralized in Rex.zone.

Compensation and Growth

Competitive pay based on task complexity, throughput, and quality scores. Clear advancement path from annotator to reviewer to QA lead and domain specialist. Senior roles influence guideline design, gold-set creation, and evaluation methodology to drive annotation guidelines compliance and model performance improvement.

Data Labeling Remote Jobs: FAQs

  • Q: What is data labeling in the context of AI/ML training?

    Data labeling is the process of annotating text, images, audio, or video with structured tags so models can learn patterns. On Rex.zone, labelers contribute to RLHF, prompt evaluation, NER, computer vision annotation, and content safety tasks that feed LLM training pipelines.

  • Q: Are these roles fully remote?

    Yes. Most roles on Rex.zone are remote, with some projects requesting overlapping hours for reviews or QA syncs.

  • Q: What experience level is required?

    We offer entry-level, mid-level, and senior QA lead roles. Entry-level candidates complete calibration tasks to demonstrate accuracy before joining projects.

  • Q: What employment types are available?

    Full-time, part-time, contract, freelance, and temporary projects are available. Some roles are project-based with variable weekly hours.

  • Q: Which domains can I work in?

    NLP (NER, classification, summarization), computer vision (bounding boxes, segmentation), content safety labeling, and LLM evaluation including RLHF and prompt testing.

  • Q: What tools will I use?

    You’ll primarily use Rex.zone’s secure annotation and QA tooling. Some projects integrate model-assisted labeling and third-party CV tools while maintaining centralized QA in Rex.zone.

  • Q: How is pay determined?

    Compensation depends on task complexity, throughput, and quality metrics like inter-annotator agreement. Senior reviewers and QA leads earn higher rates.

  • Q: Do I need technical skills?

    Basic familiarity with AI/ML concepts helps, but meticulous attention to detail and guideline adherence are most important. Scripting experience is a plus for advanced roles.

  • Q: What about data privacy and NDAs?
