About the Role

You will deliver high-quality labeled datasets and human feedback signals for AI/ML systems. The work includes RLHF tasks (pairwise preference ranking and justification), prompt evaluation, QA evaluation, and classic data labeling for NLP and computer vision. You will follow detailed annotation guidelines, document edge cases, and collaborate asynchronously with reviewers to ensure training data quality and measurable model performance improvement.

What You Will Do

Core responsibilities include: (1) Label and categorize text, image, and multimodal content according to taxonomy and policy, (2) Perform RLHF preference ranking to support reward modeling, (3) Execute prompt evaluation and response quality scoring for LLM evaluation, (4) Conduct QA evaluation audits, identify ambiguity, and propose guideline updates, (5) Perform named entity recognition and span labeling for NLP datasets, (6) Support content safety labeling including policy alignment and sensitive content handling, (7) Maintain annotation throughput, accuracy targets, and detailed decision logs for reviewer traceability.

Projects and Domains You May Support

Common project tracks include: large language model evaluation, conversational AI safety, retrieval-augmented generation grading, prompt-response pair scoring, NER dataset creation, computer vision bounding boxes and segmentation, OCR verification, content moderation and policy labeling, and multilingual NLP annotation. You may work with AI labs, tech startups, BPOs, or annotation vendors depending on client demand via Rex.zone.

Requirements

Required: experience with structured labeling workflows, strong written reasoning for consistent labeling decisions, ability to follow annotation guidelines compliance with high precision, and comfort working with QA review loops. Preferred: prior RLHF, prompt evaluation, LLM evaluation, NER, or computer vision annotation experience; familiarity with common error taxonomies; ability to explain disagreement cases clearly and propose guideline clarifications.

Quality and Performance Expectations

You will be evaluated on training data quality, inter-annotator agreement, guideline adherence, and effective handling of edge cases. Expect structured QA evaluation cycles, calibration sessions, and periodic gold-set checks. Successful annotators improve model performance by producing consistent labels, accurate preference rankings, and well-documented rationales.

How to Apply on Rex.zone

Apply through Rex.zone by submitting a profile that highlights relevant data labeling experience, RLHF or prompt evaluation work, and domain familiarity (NLP, computer vision annotation, content safety labeling). Include examples of guideline-driven decisions, QA experience, and any prior work improving annotation consistency or training data quality.

Frequently Asked Questions

  • Q: What are remote data annotator jobs in Manchester?

    These are remote roles where you create and validate labeled training data for AI/ML models. Tasks commonly include data labeling, named entity recognition, computer vision annotation, content safety labeling, and LLM evaluation work such as RLHF preference ranking and prompt evaluation.

  • Q: Is this role remote and full-time?

    Yes. The role is explicitly marked Remote and FULL_TIME, with work delivered asynchronously through online tooling and QA review workflows.

  • Q: What is RLHF and why is it part of data annotation?

    RLHF (Reinforcement Learning from Human Feedback) is a method for improving model behavior using human preference signals. Annotators provide pairwise rankings and rationales that help train reward models and improve large language model evaluation outcomes.

  • Q: What tools or workflows will I use?

    You will use web-based annotation tools, guideline documents, and QA evaluation workflows such as calibration tasks, gold-set checks, and reviewer feedback loops to maintain annotation guidelines compliance and training data quality.

  • Q: What skills should I highlight to match the job intent?

    Highlight data annotation and data labeling experience, RLHF, prompt evaluation, QA evaluation, annotation guidelines compliance, training data quality practices, and domain exposure to NLP, named entity recognition, computer vision annotation, content safety labeling, and LLM training pipelines.

  • Q: What types of employers hire for this work?

    Employers commonly include AI labs, tech startups, BPOs, and annotation vendors that build datasets and evaluation benchmarks for NLP, computer vision, and LLM training pipelines.
