About AI Training and LLM Evaluation

AI training is the human side of building artificial intelligence. People review examples, assess model responses, and provide feedback that helps AI systems become more accurate, clear, useful, and aligned with instructions.

In this engagement, your linguistic expertise will support evaluation and reinforcement learning from human feedback (RLHF). Your assessments will help identify where large language model responses succeed or fall short.

• Remote work that can fit around other commitments.
• Directly influence how advanced AI systems communicate.
• Apply specialist language knowledge to practical model-improvement tasks.

The Linguistics Specialist Role

OpenTrain AI is seeking expert linguistics specialists with native U.S. English proficiency for a remote contractor engagement. You will carefully review conversations between humans and large language models, assess response quality against defined guidelines, and communicate nuanced findings clearly in English.

The engagement is focused on LLM language quality and instruction-following evaluation. The project is classified as audio-related AI-training work and includes evaluation-rating and RLHF activities.

• Location: Remote, with candidates required to be based in the United States.
• Language: English; native or bilingual English proficiency required.
• Experience level: Expert.
• Engagement type: Contractor.
• Pay: $40–$50 USD per hour.
