Job Opening: Remote Data Labeling Specialist (Vancouver)

Title: Remote Data Labeling Specialist (Vancouver) 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: data labeling, data annotation, RLHF, QA evaluation, prompt evaluation, named entity recognition, 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 consistent, policy-aligned annotations used to train and evaluate AI models. Typical work includes data labeling for text classification, named entity recognition (NER), summarization quality checks, RLHF preference ranking, prompt evaluation, and content safety labeling. You will also support QA evaluation by reviewing labeled samples for accuracy, guideline compliance, ambiguity resolution, and edge case handling, helping improve training data quality and downstream model performance.

Key Responsibilities

You will: - Apply annotation guidelines compliance across NLP and computer vision tasks. - Perform RLHF rankings and evaluation to align model behavior with human preferences. - Execute prompt evaluation and response quality scoring for LLM evaluation. - Conduct QA evaluation, sampling audits, and error categorization to reduce label noise. - Label content safety categories (e.g., harassment, self-harm, hate) using policy taxonomies. - Collaborate with project leads to refine rubrics, resolve disagreements, and document decisions. - Track productivity and accuracy metrics to support model performance improvement.

Workstreams You May Support

Depending on project needs, you may work on: - NLP data labeling: NER, intent classification, sentiment, topic labeling, summarization evaluation. - LLM training pipelines: instruction-following evaluation, pairwise preference ranking, rubric-based grading. - Computer vision annotation: bounding boxes, polygons, keypoints, segmentation, OCR validation. - Content safety labeling: policy-based moderation labels and severity scoring. - Multimodal tasks: text-image relevance, caption validation, VQA-style evaluation.

Required Qualifications

- Experience applying structured guidelines to data annotation or QA evaluation work. - Strong written communication for consistent label rationale and disagreement resolution. - Comfort working with ambiguous examples, edge cases, and evolving rubrics. - Familiarity with NLP, RLHF, or LLM evaluation concepts (training data quality, preference ranking, prompt evaluation). - Ability to maintain accuracy at production scale and meet full-time delivery expectations.

Preferred Qualifications

- Prior work with annotation platforms and audit workflows. - Exposure to computer vision annotation tools (boxes, polygons, segmentation). - Experience with content safety labeling or policy taxonomy interpretation. - Experience documenting guidelines, building QA checklists, or running inter-annotator agreement checks.

Remote Work Notes (Vancouver Applicants)

This is a Remote role. You can be based in Vancouver while working with distributed teams. Projects may require overlap with US business hours, and task availability can vary by domain (NLP, computer vision, content safety, LLM training pipelines).

Frequently Asked Questions

  • Q: What are remote data labeling jobs in Vancouver?

    They are Remote roles that can be performed from Vancouver, focused on data labeling and data annotation tasks used in AI/ML training workflows. Work may include NLP labeling (e.g., named entity recognition), RLHF preference ranking, prompt evaluation, computer vision annotation, and content safety labeling.

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

    This posting is FULL_TIME. However, remote data labeling work in the market often also appears as contract or freelance, and Rex.zone may list those options depending on project needs.

  • Q: What is RLHF and why is it included in data labeling?

    RLHF (Reinforcement Learning from Human Feedback) is a training approach where humans rank or rate model outputs to guide model alignment. In practice, it looks like preference ranking, rubric grading, and prompt evaluation tasks that improve large language model evaluation and model performance improvement.

  • Q: What does QA evaluation mean in data annotation work?

    QA evaluation is the quality assurance process for labeled data, including audits, sampling checks, guideline compliance reviews, and error categorization. It improves training data quality and reduces inconsistencies that can degrade model performance.

  • Q: What skills should I highlight for remote data labeling jobs?

    Highlight data labeling, data annotation, annotation guidelines compliance, QA evaluation, prompt evaluation, RLHF, named entity recognition, computer vision annotation, content safety labeling, and familiarity with LLM training pipelines.

  • Q: What kinds of employers hire for remote data labeling?

    AI labs, tech startups, enterprise AI teams, BPOs, and specialized annotation vendors hire for data labeling and LLM evaluation, often across NLP, computer vision, and content safety domains.

  • Q: Are there entry-level or senior paths for data labeling work?

    Yes. Entry-level roles focus on executing labeling tasks accurately, while senior roles may include rubric design, QA evaluation leadership, resolving edge cases, and improving annotation workflows. This posting targets Mid-Senior level experience.
