About the Role

You will support AI/ML teams by executing and improving data labeling and evaluation workflows used in LLM training pipelines. Your work will span RLHF tasks, prompt evaluation, QA evaluation, and training data quality checks across domains like NLP, named entity recognition, computer vision annotation, and content safety labeling. You will follow annotation guidelines compliance, document edge cases, and help reduce ambiguity so models learn consistently.

What You Will Do

["Perform data labeling for text and/or vision datasets to meet training data quality targets","Complete RLHF-style preference ranking and response quality scoring to support model performance improvement","Run prompt evaluation and QA evaluation to identify errors, hallucinations, policy violations, and formatting issues","Apply named entity recognition and taxonomy tagging using clear annotation guidelines compliance","Conduct content safety labeling for sensitive, policy, and restricted content categories","Audit datasets for consistency, duplicates, label noise, and distribution gaps; propose fixes","Write concise rationales and escalate ambiguous cases to improve guidelines","Track throughput and quality metrics (accuracy, agreement rates) and participate in calibration sessions","Collaborate with engineers and QA to validate changes to labeling rubrics and evaluation checklists","Support experimentation by comparing model outputs across variants and documenting findings"]

Who This Is For

["Candidates seeking entry-level STEM jobs in India with real AI/ML exposure","Graduates in CS, IT, ECE, EE, Math, Physics, Statistics, Data Science, or related STEM fields","Applicants who can reason carefully, follow policies, and maintain high attention to detail","People comfortable working with structured rubrics, edge cases, and fast iteration cycles","Individuals interested in AI labs, tech startups, BPOs, and annotation vendors supporting LLM development"]

Required Skills

["STEM fundamentals and strong analytical reasoning","Comfort with Python and SQL for basic data checks (filters, counts, joins) and simple scripts","Understanding of NLP concepts (tokens, entities) and/or computer vision annotation concepts (bounding boxes, segmentation)","Experience applying annotation guidelines compliance and documenting decisions","Ability to perform QA evaluation, spot inconsistencies, and propose improvements","Clear written communication for rationales and issue reporting"]

Nice to Have

["Prior exposure to RLHF tasks, preference ranking, or evaluation rubrics","Familiarity with content safety labeling, policy taxonomies, and red-teaming concepts","Experience with dataset auditing, inter-annotator agreement, or quality sampling","Knowledge of LLM evaluation methods (rubric scoring, pairwise comparisons, error categorization)","Experience supporting remote teams across time zones"]

Working Model and Team

This is a Remote, FULL_TIME role with structured daily workflows, QA checks, and calibration sessions to keep labels consistent. You will collaborate with engineering and QA stakeholders to ensure datasets meet training data quality standards and improve model performance over time.

How to Apply on Rex.zone

["Search Rex.zone for 'Entry-Level STEM Jobs in India' to find the matching posting","Submit your application with a resume highlighting STEM coursework/projects and any labeling/evaluation exposure","Be prepared for a short evaluation focused on annotation guidelines compliance, QA evaluation, and reasoning","If selected, complete onboarding and start contributing to LLM training pipelines"]
