About the Role

You will work remotely to produce and evaluate high-quality labeled datasets used in AI/ML training. Daily work includes text annotation for NLP tasks (classification, NER, summarization), RLHF ranking and preference labeling, prompt evaluation for instruction-following models, and QA evaluation to enforce training data quality. You will apply detailed labeling rubrics, document edge cases, and contribute feedback that supports model performance improvement across large language model evaluation and content safety labeling.

Key Responsibilities

You will: - Execute data labeling across NLP, computer vision annotation, and content safety labeling queues. - Perform RLHF tasks including pairwise ranking, preference data creation, and rationale capture. - Conduct prompt evaluation and response grading for LLM training pipelines. - Follow annotation guidelines compliance, track exceptions, and escalate ambiguous cases. - Complete QA evaluation (self-checks and peer review) to maintain training data quality. - Apply named entity recognition standards and taxonomy rules where required. - Meet throughput and accuracy targets while maintaining consistent decision-making.

Required Qualifications

You have: - Mid-to-senior experience in AI data annotation, data labeling, or QA evaluation workstreams. - Familiarity with RLHF, prompt evaluation, and large language model evaluation concepts. - Strong reading comprehension and attention to detail for policy-based content safety labeling. - Comfort working with annotation tools, guideline documents, and audit workflows. - Ability to reason about edge cases, write clear notes, and support calibration sessions.

Preferred Qualifications

Nice to have: - Experience with named entity recognition projects and schema-driven labeling. - Exposure to computer vision annotation (bounding boxes, polygons, keypoints) and image QA. - Experience supporting AI labs, tech startups, BPOs, or annotation vendors. - Familiarity with dataset sampling, inter-annotator agreement, and error taxonomies.

Workflow, Quality, and Metrics

Work is organized in production queues with clear acceptance criteria. You will participate in calibration, apply consistent rubric interpretation, and contribute to training data quality through spot checks and QA evaluation. Typical metrics include guideline adherence, precision/recall-oriented checks for NER, consensus alignment for RLHF rankings, and defect rate reduction tied to model performance improvement.
