Remote Data Annotator Jobs in Vancouver

About the Role

As a Remote Data Annotator based in Vancouver, you will label and evaluate text, image, and multimodal data used in production AI systems. Your work includes RLHF preference comparisons, prompt evaluation for helpfulness/harmlessness, QA evaluation of model outputs, and structured data labeling for NLP and computer vision annotation. You will follow detailed annotation guidelines, document edge cases, and collaborate with operations and engineering partners to ensure consistent training data quality across large language model evaluation and content safety labeling tasks.

Key Responsibilities

You will: create accurate labels for NLP tasks such as named entity recognition, classification, summarization, and intent tagging; perform RLHF ranking and pairwise preference judgments to align model behavior; execute QA evaluation to audit annotation guidelines compliance and reduce inter-annotator disagreement; run prompt evaluation workflows and flag failure modes like hallucinations, policy violations, or unsafe content; annotate computer vision data including bounding boxes, polygons, keypoints, segmentation masks, and captioning where applicable; write clear rationales for ambiguous cases and propose guideline clarifications; track throughput and quality metrics that influence model performance improvement; protect sensitive information by applying privacy and content safety labeling standards.

Required Qualifications

You have: professional experience in data annotation, data labeling, QA, evaluation, or trust & safety operations; strong written English and the ability to apply consistent rubrics to subjective judgments; familiarity with NLP concepts (tokenization, entities, intents) and/or computer vision annotation formats; comfort working in remote, asynchronous workflows with ticketing and QA review; high attention to detail, strong reasoning, and the ability to follow annotation guidelines compliance rules; proficiency with web-based labeling tools and spreadsheets; ability to meet full-time productivity and quality targets.

Preferred Qualifications

Nice to have: prior RLHF experience, LLM training pipelines exposure, or large language model evaluation work; experience with content safety labeling, policy enforcement, or moderation taxonomies; experience with measurement of training data quality and adjudication processes; background in linguistics, cognitive science, computer science, or analytics; familiarity with inter-annotator agreement methods and error analysis; experience supporting AI labs, tech startups, BPOs, or annotation vendors.

Tools and Workflows

Common workflows include: guideline-driven labeling with QA sampling; gold set calibration and drift checks; RLHF preference ranking and rubric-based scoring; prompt evaluation with structured rationales; NER tagging, span labeling, and taxonomy mapping; computer vision annotation (bounding boxes, polygons, segmentation); escalation paths for ambiguous or high-risk content; documentation updates to improve annotation guidelines compliance and downstream model performance improvement.

Compensation and Benefits

This is a full-time remote role with annual pay in USD within the stated range. Compensation depends on task complexity, domain expertise (NLP, computer vision, content safety), and demonstrated training data quality outcomes. Benefits and scheduling details vary by project on Rex.zone and may include flexible shifts, ongoing calibration, and paid QA time where applicable.

How to Apply on Rex.zone

Apply through Rex.zone by submitting your profile, availability, and relevant evaluation or data labeling experience. Be prepared to complete a skills screening that may include annotation guidelines compliance, QA evaluation scenarios, and sample RLHF or prompt evaluation tasks. After onboarding, you may be matched to projects for LLM training pipelines, content safety labeling, NLP tagging, or computer vision annotation depending on your strengths.

Frequently Asked Questions

Q: What are remote data annotator jobs in Vancouver?
These are remote roles where Vancouver-based professionals label and evaluate datasets used to train and validate AI models. The work commonly includes data labeling for NLP, computer vision annotation, RLHF preference ranking, prompt evaluation, and QA evaluation to improve training data quality and model performance.
Q: Is this role fully remote?
Yes. The role is explicitly Remote, and workflows are designed for distributed teams with asynchronous reviews, QA sampling, and calibration sessions.
Q: What types of tasks will I work on?
Typical tasks include named entity recognition, classification, summarization review, content safety labeling, RLHF rankings, prompt evaluation of LLM outputs, and computer vision annotation such as bounding boxes or segmentation, depending on the project.
Q: Do I need prior RLHF experience?
RLHF experience is helpful but not always required. Many projects provide rubrics, examples, and calibration rounds so you can perform preference ranking and QA evaluation consistently.
Q: How does quality assurance work in data annotation?
QA typically includes guideline training, gold set testing, reviewer spot checks, inter-annotator agreement monitoring, adjudication of disagreements, and iterative updates to annotation guidelines compliance requirements.
