Entry-Level Data Annotation Jobs (Work From Home)

Entry-level data annotation jobs (work from home) on Rex.zone connect you to real AI/ML training workflows. As a data annotation specialist, you label text, images, audio, and video for RLHF, QA evaluation, prompt evaluation, named entity recognition, computer vision annotation, content safety labeling, and LLM training pipelines. Your careful labels drive training data quality, annotation guidelines compliance, and model performance improvement, including large language model evaluation tasks. Explore remote, contract, freelance, part-time, and full-time roles with AI labs, tech startups, BPOs, and annotation vendors—discover opportunities and apply directly on Rex.zone.

Key Responsibilities

Create high-quality labels across modalities: text (NER, sentiment, summarization scoring), images (bounding boxes, polygons, segmentation), audio (transcription, speaker ID), and video (object tracking). Execute RLHF tasks such as prompt evaluation, pairwise ranking, and preference modeling. Perform content safety labeling aligned to policy taxonomies. Follow annotation guidelines precisely, surface ambiguities, and suggest improvements. Complete QA checks, maintain inter-annotator agreement, and contribute to gold-standard test sets that enable model performance improvement and large language model evaluation.

Required Qualifications

Entry-level friendly. Strong attention to detail, reading comprehension, and consistency. Professional written English; additional languages are a plus. Reliable internet, computer, and private workspace. Ability to follow instructions, meet throughput targets, and pass qualification quizzes. Comfort with web-based tools and spreadsheets. Commitment to data privacy and ethical AI practices.

Preferred Skills

Familiarity with NLP concepts (tokenization, NER), computer vision basics (bounding boxes vs. polygons), and evaluation metrics (precision/recall, agreement). Exposure to RLHF, prompt engineering, and instruction tuning. Basic scripting (Python/regex) for productivity is helpful but not required. Experience with annotation tools such as Label Studio, Prodigy, or CVAT. Flexibility to work across time zones and domains (content safety, e-commerce, healthcare—where permitted).

Tools and Platforms

You may use platforms like Rex.zone’s integrated workspace and common industry tools for data labeling, prompt evaluation, and QA. Expect task queues, guideline wikis, gold checks, and automated quality analytics. You’ll work within standardized pipelines that ensure training data quality and annotation guidelines compliance for AI labs, startups, BPOs, and annotation vendors.

Work Arrangements and Compensation

Remote-first roles spanning freelance, contract, part-time, and full-time. Pay is typically per task, hour, or project milestone, with bonus eligibility for quality and throughput. Entry-level rates vary by geography and domain (NLP, computer vision, content safety). Projects may be short-term (pilot datasets) or ongoing production programs. Senior tracks include QA lead, domain reviewer, and task curator.

Quality and Impact

Your labels power model training, evaluation, and safety. We measure quality via agreement rates, gold questions, rubric alignment, and error analysis. Feedback loops, calibration sessions, and clear escalation paths help maintain consistency. High performers help refine guidelines, reduce ambiguity, and unlock model performance improvement across LLM training pipelines.

Career Growth

Start as an entry-level annotator and grow into senior rater, QA reviewer, project coordinator, data curator, or prompt evaluation specialist. Exposure to RLHF, content safety, and computer vision annotation broadens your skill set. Many roles serve as a stepping stone to ML data operations, evaluation engineering, and model governance.
