Title: Remote AI Data Annotation Specialist (Miami) 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: AI data annotation, data labeling, RLHF, LLM evaluation, prompt evaluation, QA evaluation, named entity recognition, computer vision annotation, content safety labeling, annotation guidelines, training data quality Salary Currency: USD Salary Min: 63360 Salary Max: 126720 Pay Period: YEAR

About the Role

You will work remotely from Miami (or anywhere in the US) to produce and evaluate high-quality training datasets for AI/ML systems. Daily work includes data labeling across NLP and computer vision tasks, RLHF preference ranking, prompt evaluation for large language model evaluation, and QA evaluation to ensure annotation guidelines compliance. You will collaborate with cross-functional stakeholders to improve training data quality, reduce ambiguity in labeling instructions, and drive model performance improvement through consistent, defensible annotation decisions.

Key Responsibilities

["Annotate and review text datasets for NLP tasks such as named entity recognition, classification, summarization quality checks, and reasoning consistency","Perform RLHF tasks including preference ranking, rubric-based scoring, and evaluation of assistant responses for helpfulness, honesty, and harmlessness","Conduct prompt evaluation and QA evaluation to identify edge cases, label noise, and guideline gaps that affect large language model evaluation","Label computer vision data (bounding boxes, polygons, keypoints, segmentation masks) and validate inter-annotator agreement for accuracy","Apply content safety labeling and policy-based moderation labels for sensitive content categories and safety risk tiers","Document decisions, propose improvements to annotation guidelines, and support calibration sessions to improve consistency","Track quality metrics (precision/recall proxies, disagreement rates, audit pass rates) and contribute to training data quality initiatives"]

Required Qualifications

["Mid-Senior experience in AI data annotation, data labeling, QA evaluation, or related data operations roles","Hands-on familiarity with LLM evaluation concepts, RLHF workflows, and rubric-based scoring","Strong written communication and ability to justify labeling decisions with clear rationale","Ability to follow annotation guidelines compliance requirements and maintain high attention to detail","Comfort working in remote, metrics-driven production environments with iterative feedback"]

Preferred Qualifications

["Experience with named entity recognition, taxonomy design, and error analysis for NLP datasets","Exposure to computer vision annotation tools and segmentation/box quality standards","Prior work on content safety labeling, policy interpretation, or trust-and-safety style evaluation","Understanding of LLM training pipelines and how data quality impacts model performance improvement","Experience collaborating with AI labs, tech startups, BPOs, or annotation vendors"]

What You Will Work On

["Large language model evaluation for instruction following, reasoning quality, and factuality checks","RLHF preference data and prompt evaluation to improve alignment and user experience","Training data quality audits to reduce label noise and guideline drift","Multi-modal annotation projects spanning NLP, computer vision annotation, and content safety labeling"]

Compensation and Benefits

["Salary range: 63360 to 126720 USD per year","Full-time remote role (Remote Type: Remote)","Structured onboarding, calibration, and ongoing QA evaluation feedback loops","Opportunities to work across NLP, computer vision annotation, and LLM evaluation programs"]

How to Apply on Rex.zone

["Prepare a short summary of your annotation experience (NLP, computer vision annotation, RLHF, QA evaluation)","Highlight familiarity with annotation guidelines compliance and training data quality practices","Apply through Rex.zone and complete any required screening tasks for large language model evaluation or data labeling"]
