Remote AI Jobs India

Remote AI jobs in India at Rex.zone focus on search-recognizable AI/ML job entities such as LLM evaluation, RLHF, data labeling, prompt evaluation, and QA for training data quality. You will support real-world AI training workflows used by AI labs, tech startups, BPOs, and annotation vendors, improving large language model evaluation and model performance improvement through guideline-driven annotation, content safety labeling, and structured feedback. Explore full-time remote roles that span NLP, computer vision annotation, named entity recognition, and LLM training pipelines, with clear standards for annotation guidelines compliance and measurable quality metrics.

Remote AI Jobs India — LLM Evaluation & RLHF Specialist

About the Role

You will work remotely with distributed teams to evaluate and improve AI/ML systems by producing high-quality human feedback and annotations. The work includes RLHF-style ranking, prompt response evaluation, QA evaluation against rubrics, and writing structured rationales that support model performance improvement. You will follow annotation guidelines compliance standards, contribute to training data quality, and help maintain consistent labeling across multilingual and domain-specific datasets used in LLM training pipelines.

What You Will Do

Core workflows include: (1) LLM evaluation of generated responses for correctness, helpfulness, and policy alignment; (2) RLHF tasks such as pairwise preference ranking and justification writing; (3) prompt evaluation for instruction-following and reasoning quality; (4) data labeling for NLP tasks including named entity recognition, classification, and retrieval relevance; (5) content safety labeling for sensitive or policy-restricted content; (6) QA evaluation using sampling, audits, and disagreement resolution to improve training data quality.

Key Skills and Tools

You should be comfortable with annotation platforms, rubric-based grading, and quality metrics such as inter-annotator agreement. Familiarity with NLP concepts (intent, entities, NER), LLM behavior evaluation, and content safety taxonomies is important. Experience collaborating remotely, documenting edge cases, and improving annotation guidelines is expected. Exposure to computer vision annotation is a plus but not required.

Who This Is For

This role fits candidates seeking remote, full-time AI work in India supporting global teams. It is suitable for professionals with experience in evaluation, QA, or structured analysis who can apply consistent reasoning and follow policies. Backgrounds may include AI operations, data annotation, QA, trust and safety, linguistics, or engineering-adjacent roles in tech startups, AI labs, BPOs, or annotation vendors.

Quality and Performance Expectations

Success is measured through training data quality, annotation guidelines compliance, audit pass rates, calibration performance, and turnaround time. You will be expected to handle ambiguity, flag guideline gaps, propose clearer definitions, and maintain consistent judgments across repeated evaluation tasks. You will participate in calibration sessions and respond to QA evaluation feedback to reduce error patterns.

Work Modifiers and Role Variants

While this posting is for a full-time remote role, Rex.zone listings may include contract, freelance, entry-level, and senior variants depending on project needs. Domain coverage can include NLP, computer vision annotation, content safety labeling, and LLM training pipelines. Employer contexts may include AI labs, tech startups, BPOs, and annotation vendors supporting global model development.

How to Apply

Apply through Rex.zone with a resume highlighting RLHF, LLM evaluation, QA evaluation, data labeling, and any domain expertise (NLP, content safety, or multilingual evaluation). Include examples of rubric-based work, guideline interpretation, or quality improvement initiatives that demonstrate model performance improvement contributions.
