Work from home as a data annotation specialist on Rex.zone, labeling text, images, audio, and video to build high-quality datasets. Tasks include named entity recognition, bounding boxes, segmentation, transcription, rating prompts and responses, and enforcing content safety policies. You will contribute to RLHF and LLM training pipelines alongside ML engineers and QA reviewers.
Deliver training data quality, ensure annotation guidelines compliance, drive model performance improvement, and support large language model evaluation. Execute precise labeling, follow taxonomies and ontologies, document edge cases, escalate ambiguities, and collaborate in double-pass reviews. Maintain inter-annotator agreement and contribute to gold standards and audit trails.
Strong attention to detail, consistency, and ethical judgment. Solid reading comprehension and English fluency; multilingual skills are a plus. Familiarity with ML concepts, labeling tools, spreadsheets, and basic Python or regex for data hygiene. Ability to follow rubrics, meet SLAs, and communicate clearly. Entry-level and senior openings are available.
Projects use platforms such as Label Studio, CVAT, Prodigy, SuperAnnotate, and custom Rex.zone workflows with templates, hotkeys, and validators. Expect QA evaluation, preference ranking for RLHF, RAG evaluation, test-set curation, calibration sessions, and feedback loops designed to improve reliability and throughput.
Remote-first roles including contract, freelance, full-time, part-time, and seasonal projects. Choose flexible hours, weekday or weekend shifts, and time-zone friendly schedules. Compensation may be per-task, per-hour, or milestone-based with productivity bonuses and quality incentives.
NLP (NER, sentiment, summarization, redaction), computer vision (bounding boxes, polygons, segmentation), content safety (policy enforcement, risk tagging), speech and audio (transcription, diarization), OCR, and LLM training and evaluation. Specialized projects include biomedical NLP, financial documents, and multilingual datasets.
Collaborate with AI labs, tech startups, BPOs, and annotation vendors through Rex.zone. Partner with ML engineers, research scientists, data operations teams, and product managers who rely on accurate labels to ship models and evaluate performance in production.
Competitive rates with performance bonuses, QA reviewer tracks, and opportunities to become a team lead or project manager. Access training, calibration sessions, and certifications to broaden your scope from entry-level annotation to senior quality roles.
