LinkedIn’s Trust Review Operations team protects our global community by ensuring AI‑driven moderation systems are safe, accurate, and reliable. As an AI Prompt Engineer, you will design, test, and refine prompts and workflows that assist in content moderation, improve detection quality, and support reviewer decision‑making.

This role is ideal for someone who enjoys hands‑on experimentation, analyzing model behaviour, and partnering with Policy, Engineering, and Data Science to improve safety outcomes.

What You’ll Do:

Prompt Design, Testing & Optimization

• Design and refine prompts for classification, risk detection, case summarization, and reviewer support.

• Run prompt experiments to diagnose issues such as hallucinations, misclassifications, bias, or inconsistent behaviour.

• Help maintain evaluation frameworks for accuracy, safety, and reliability.

AI Case Support & Risk Mitigation

• Support AI‑assisted workflows in resolving medium‑ and high‑risk cases.

• Identify model errors, document patterns, and recommend improvements to reduce operational risk.

• Contribute to operational guardrails and escalation criteria for AI behaviour.

Incident Management & Quality Monitoring

• Flag AI output issues (e.g., inconsistent decisions, low‑confidence outcomes, override trends).

• Participate in incident reviews and help document root‑cause insights.

Policy & Regulatory Alignment

• Ensure AI outputs align with platform policies, MDSS, and relevant regulations (e.g., DSA).

• Work with Policy teams to translate reviewer feedback into clearer prompts and rules.

Feedback Integration & Model Improvement

• Collect feedback from reviewers, policy partners, and operational teams to refine prompts.

• Translate qualitative insights into structured requirements for Engineering and Data Science.

Data Analysis & Experimentation

• Analyze prompt and model performance using SQL or dashboards.

• Track trends such as classifier drift, emerging abuse patterns, or changes in harmful content.

• Contribute data‑backed insights that inform roadmap and workflow updates.

Basic Qualifications

• Bachelor’s degree in Data Science, AI/ML, Engineering, Policy, or related field (or equivalent experience).

• 2+ years of experience in Trust & Safety, content moderation, AI operations, quality, or policy.

• 1+ years experience designing or testing prompts or working with LLMs / classification models.

• 2+ years experience using data tools (e.g. SQL, Python) to evaluate model and prompt performance.  

   

Preferred Qualifications

• Understanding of Trust & Safety policies, global regulations (e.g., DSA), and safety standards.

• Ability to analyze model outputs and identify patterns, gaps, and risks.

• Strong written communication skills for writing clear, reproducible prompt instructions.

• Familiarity with evaluation metrics (precision, recall, FPR, FDR) and model quality testing.

• Experience collaborating with Product, Engineering, Policy, or Data Science teams.

• Exposure to human‑in‑the‑loop workflows, generative AI systems, or safety‑centric model evaluation.
