LLM Evaluator (Model Response Analyst)

About the role

We are looking for a detail‑oriented LLM Evaluator to assess and improve the performance of large language models. You will work remotely with a global team, reviewing AI‑generated content for accuracy, coherence, safety, bias, and alignment with our guidelines.

Key responsibilities

• Evaluate and rank model‑generated text using complex rubrics covering factuality, coherence, safety, instruction‑following, and creativity.
• Compare multiple model responses to the same prompt, select the preferred output, and justify your choice.
• Provide concise feedback to modeling and training teams on recurring failure patterns.
• Design adversarial prompts to expose biased, harmful, or insecure model behavior.
• Collaborate with QA to refine evaluation guidelines for ambiguous edge cases.
• Participate in cross‑checking sessions to calibrate scoring standards and ensure inter‑rater reliability.
• Analyze underperforming outputs, hypothesize root causes, and flag novel model behaviors.

Required profile

• Minimum 2 years of professional experience in computational linguistics, data analysis, technical writing, NLP quality assurance, or cognitive science.
• Bachelor’s degree in Computer Science or a related field.
• Strong ability to craft prompts that test model limits and to explain why outputs are good or bad.
• Experience with Reinforcement Learning from Human Feedback (RLHF) data collection and evaluation.

Required skills

• Prompt engineering
• Reinforcement Learning from Human Feedback (RLHF)
• Data analysis
• A/B testing for AI models
• Dataset sourcing, cleaning, and annotation
