AI QA Trainer - LLM Evaluation - Freelance Project

Agency; United States; Remote; USD 8,300 - 90,000; Full time

Job summary

Agency seeks AI QA trainers to rigorously evaluate large language models across multilingual and domain-specific contexts. You will design tests, run regression suites, and document failure modes to raise the bar for model reasoning, reliability, and safety.

You’ll work on adversarial red-teaming, automation with Python/SQL, and dashboards to track quality deltas. A strong background in ML/AI QA and tooling signals fit.

Qualifications

• A bachelor’s, master’s, or PhD in CS/DS/CL/ statistics is ideal.
• Shipped QA for ML/AI systems and safety/red-team experience.
• Experience with test automation frameworks (e.g., PyTest).
• Hands-on with LLM eval tooling (OpenAI Evals, RAG evaluators, W&B).

Responsibilities

• Converse with the model on real-world scenarios and evaluation prompts, verify factual accuracy and logical soundness.
• Design and run test plans and regression suites, build clear rubrics and pass/fail criteria.
• Capture reproducible error traces with root-cause hypotheses, and suggest improvements to prompt engineering, guardrails, and evaluation metrics.
• Partner on adversarial red-teaming, automation (Python/SQL), and dashboarding to track quality deltas over time.

Job description

Are you an AI QA expert eager to shape the future of AI? Large-scale language models are evolving from clever chatbots into enterprise-grade platforms. With rigorous evaluation data, tomorrow’s AI can democratize world-class education, keep pace with cutting-edge research, and streamline workflows for teams everywhere. That quality begins with you—we need your expertise to harden model reasoning and reliability.

We’re looking for AI QA trainers who live and breathe

• model evaluation
• LLM safety
• prompt robustness
• data quality assurance
• multilingual and domain-specific testing
• grounding verification
• compliance/readiness checks

You’ll challenge advanced language models on tasks like

• hallucination detection
• factual consistency
• prompt-injection and jailbreak resistance
• bias/fairness audits
• chain-of-reasoning reliability
• tool‑use correctness
• retrieval‑augmentation fidelity
• end‑to‑end workflow validation

—documenting every failure mode so we can raise the bar.

On a typical day, you will

• converse with the model on real-world scenarios and evaluation prompts, verify factual accuracy and logical soundness
• design and run test plans and regression suites, build clear rubrics and pass/fail criteria
• capture reproducible error traces with root‑cause hypotheses, and suggest improvements to prompt engineering, guardrails, and evaluation metrics (e.g., precision/recall, faithfulness, toxicity, and latency SLOs)
• partner on adversarial red‑teaming, automation (Python/SQL), and dashboarding to track quality deltas over time

A bachelor’s, master’s, or PhD in computer science, data science, computational linguistics, statistics, or a related field is ideal; shipped QA for ML/AI systems, safety/red‑team experience, test automation frameworks (e.g., PyTest), and hands‑on work with LLM eval tooling (e.g., OpenAI Evals, RAG evaluators, W&B) signal fit.

Skills that stand out include

• evaluation rubric design
• adversarial testing/red‑teaming
• regression testing at scale
• bias/fairness auditing
• grounding verification
• prompt and system‑prompt engineering
• test automation (Python/SQL)
• high‑signal bug reporting

Clear, metacognitive communication—“showing your work”—is essential.

Ready to turn your QA expertise into the quality backbone for tomorrow’s AI?

We offer a pay range of $6-to- $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above.

As a contractor you’ll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
