Remote STEM & Technical Expert: Rubrics & AI Evaluation

AI Trainer Jobs; United States; Remote; USD 114,000 - 162,000; Full time

Job summary

AI Trainer Jobs is seeking a STEM & Technical SME to craft expert-level questions, evaluate AI outputs, and design rigorous rubrics in a remote hourly contractor role.

You will develop problems that require multi-step reasoning, identify weaknesses in frontier AI models, and translate complex judgments into clear, measurable criteria, including partial-credit standards and edge-case considerations. You will contribute to RLHF/SFT workflows while maintaining high professional standards in English.

Qualifications

• Bachelor’s degree or higher in Mathematics, Physics, Chemistry, Engineering, Computer Science, Statistics, Applied Science, or another technical discipline.
• Strong professional proficiency in English, minimum C1, with the ability to write precise technical explanations and evaluation criteria.
• 3+ years of professional, academic, research, or industry experience in your stated technical domain.
• Demonstrated advanced expertise in a clearly defined technical field or specialization.
• Ability to create challenging technical questions that require multi-step reasoning, domain expertise, or professional judgment.
• Strong ability to design detailed evaluation rubrics defining required reasoning, correct methodology, acceptable alternatives, partial-credit criteria, and critical errors.
• Ability to distinguish between a correct final answer and an answer supported by valid versus flawed reasoning.
• Comfortable reviewing and critiquing other experts’ rubrics for ambiguity, missing criteria, redundancy, technical inaccuracies, or poor scoring design.
• High attention to detail when evaluating formulas, assumptions, units, methodology, edge cases, logical consistency, and technical terminology.
• Experience with exam writing, academic grading, peer review, research review, technical QA, standards development, or assessment design is strongly preferred.
• Prior experience with AI evaluation, RLHF, SFT, benchmarking, data annotation, prompt design, or LLM evaluation is preferred.
• Reliable, self-directed, and able to deliver consistent quality in an hourly, remote contractor workflow.

Responsibilities

• Create expert-level technical questions: Develop difficult questions that test genuine technical reasoning and expose weaknesses in advanced AI systems.
• Design evaluation rubrics: Write structured criteria defining what a correct, rigorous, and complete response must contain.
• Define partial-credit standards: Identify essential reasoning steps, acceptable alternatives, minor errors, and critical failures.
• Evaluate AI-generated solutions: Assess outputs for correctness, reasoning quality, completeness, methodology, and technical precision.
• Identify hidden reasoning errors: Detect cases where an answer reaches the correct conclusion using invalid assumptions or flawed logic.
• Critique peer rubrics: Review other experts’ criteria for technical accuracy, clarity, completeness, and scoring consistency.
• Develop reference content: Produce expert answers, explanations, critiques, and other gold-standard content.
• Support AI training: Create questions, rubrics, evaluations, preference judgments, and reference-answer pairs suitable for RL and SFT workflows.
• Maintain technical rigor: Ensure content reflects appropriate professional or academic standards within the relevant discipline.
