LLM Operations Specialist (Content Moderation)

About the team
Join the forefront of AI innovation with cutting-edge advancements in AIGC and LLM technologies. As an LLM Operations Specialist, you will play a key role in leveraging AI for monetization, with a focus on content moderation.
This position offers a unique opportunity to gain end-to-end expertise from model selection to hands-on engineering solutions to put LLMs into solving real business problems. You will be able to work alongside top AI talents in ByteDance, accelerate your professional growth, and expand your skill set in a fast-paced, dynamic environment.

Responsibilities
- Model Operations – Identify the most suitable model for specific tasks, troubleshoot performance issues or errors, and provide prompt feedback to model owners (algorithm engineers).
- Model/policy Alignment – Ensure model outputs comply with organizational content policies and legal requirements through prompt engineering and other advanced techniques.
- LLM Application Management – End-to-end management of task-specific LLM applications, including but not limited to evaluation dataset preparation, prompt engineering, RAG datasets preparation, and conducting tests and iterative improvements to enhance precision/recall trade-offs.
- Incident Response & Analysis – Investigate escalations (e.g., false positives/negatives), diagnose root causes, and implement prompt, model, or solution refinements to reduce errors. Conduct root-cause analyses of systemic issues and deploy rapid fixes.
- Cross-functional Collaboration – Work closely with algorithm engineers to deploy, monitor, and maintain LLMs in production. Optimize model efficiency in terms of cost, speed, and accuracy while ensuring scalability for high-volume content. Partner with policy, legal, and compliance teams to refine enforcement policies and keep LLMs aligned with the latest guidelines. Collaborate with product and engineering teams to integrate LLMs into moderation tools and user-facing platforms.
