Title: Remote Data Annotation Specialist (North America) Date: 25-02-2026 Company: Rex.zone Country: US Remote Type: Remote Employment Type: FULL_TIME Experience Level: Mid-Senior Industry: Technology Job Function: Engineering Skills: remote data annotation, data labeling, RLHF, QA evaluation, prompt evaluation, training data quality, annotation guidelines compliance, named entity recognition, NLP, computer vision annotation, content safety labeling, LLM training pipelines Salary Currency: USD Salary Min: 63360 Salary Max: 126720 Pay Period: YEAR

About the Role

You will deliver remote data annotation for North America programs supporting AI labs, tech startups, and annotation vendors using Rex.zone. Your day-to-day work includes labeling text, image, and multimodal data; performing prompt evaluation for LLM outputs; and executing RLHF preference ranking to improve helpfulness, harmlessness, and instruction-following. You will follow detailed labeling rubrics, maintain annotation guidelines compliance, and partner with QA to uphold training data quality that drives model performance improvement.

What You Will Do

Core workflows include: (1) data labeling for NLP tasks such as named entity recognition, classification, summarization checks, and intent detection; (2) RLHF evaluation including pairwise comparisons, rationale selection, and rubric-based scoring; (3) QA evaluation using audits, inter-annotator agreement, and error taxonomy feedback; (4) computer vision annotation such as bounding boxes, polygons, keypoints, and caption verification; (5) content safety labeling for policy categories, sensitive content, and risk severity; (6) prompt evaluation and red-team style assessments to identify failure modes and improve model behavior.

Required Qualifications

You have experience executing remote data annotation or data labeling with consistent quality and throughput. You can interpret complex annotation guidelines, apply edge-case reasoning, and document decisions clearly for QA evaluation. You are comfortable working with LLM training pipelines concepts, including RLHF, prompt evaluation, and dataset iteration. You communicate well in writing, manage tasks independently in a remote setting, and deliver reliable outputs in full-time workflows.

Preferred Qualifications

Experience with named entity recognition, ontology design, or taxonomy-based labeling. Familiarity with computer vision annotation tools and verification workflows. Exposure to content safety labeling, policy interpretation, and harm mitigation. Understanding of evaluation metrics such as precision/recall basics, inter-annotator agreement, and rubric calibration. Prior work supporting AI labs, tech startups, BPOs, or annotation vendors is helpful.

Quality Standards and How Success Is Measured

Success is measured by training data quality, annotation guidelines compliance, audit pass rate, and consistency across edge cases. You will receive calibration feedback through QA evaluation, error tagging, and targeted re-training. Strong performance includes stable inter-annotator agreement, low defect rates, and clear notes that accelerate model performance improvement through dataset iteration.

Work Environment (Remote, North America)

This is a Remote, FULL_TIME role aligned to North America time zones where required by program needs. You will collaborate asynchronously through Rex.zone workflows, follow queue-based task assignments, and participate in calibration sessions for RLHF and evaluation tasks. Remote roles remain explicitly Remote; some programs may also offer contract or freelance options on Rex.zone, but this posting is for full-time hiring.

How to Apply

Apply through Rex.zone to be considered for remote data annotation jobs in North America. Your application should highlight prior data labeling experience, QA evaluation exposure, familiarity with RLHF or prompt evaluation, and examples of following detailed annotation guidelines. If selected, you may complete a short skills assessment focused on training data quality and rubric adherence.

Frequently Asked Questions

  • Q: What are remote data annotation jobs in North America?

    They are Remote roles where you label and evaluate training data used in AI/ML systems. Work may include data labeling for NLP, computer vision annotation, content safety labeling, prompt evaluation, and RLHF evaluation to improve large language model behavior.

  • Q: Is this role full-time or contract/freelance?

    This posting is for FULL_TIME Remote employment. Rex.zone may also host contract or freelance annotation projects, but this job is explicitly full-time.

  • Q: What is RLHF and how is it used here?

    RLHF (Reinforcement Learning from Human Feedback) uses human preference judgments to improve model outputs. In this role, you may rank responses, apply rubrics, and provide structured evaluations that feed into LLM training pipelines.

  • Q: What types of tasks will I do day to day?

    Typical tasks include annotation guidelines compliance checks, training data quality audits, QA evaluation, named entity recognition, prompt evaluation, computer vision annotation (when applicable), and content safety labeling for policy categories.

  • Q: Do I need an engineering background to qualify?

    Not always, but you should be comfortable with structured workflows, detailed rubrics, and quality metrics. This posting is aligned to Job Function: Engineering because it supports production AI/ML training pipelines and evaluation processes.

  • Q: How does Rex.zone fit into the workflow?

    Rex.zone is the platform where you access tasks, guidelines, calibration updates, and QA feedback. It anchors the remote workflow for submitting labeled data and evaluation results.
