(General Hire) Machine Learning Engineer Intern (Trust and Safety - CV/NLP/Multimodal LLM) - 2027 Summer

Written by the T&S Network from TikTok's posting.

Machine learning engineering internship on TikTok's algorithm team, building computer vision, NLP and multimodal models that detect content and behaviors violating community guidelines and related regulations. The team works on improving recognition of violating content on the platform and on the distributed training framework behind those models.

What you'd do

• Explore few-shot and zero-shot strategies with multimodal large models for content safety scenarios.
• Build moderation models designed to generalize across new risk types.
• Help design reinforcement learning-based data mining and Chain-of-Thought annotation frameworks for complex risks.
• Build risk ranking and recall systems to raise coverage and accuracy on high-risk content.
• Optimize the distributed model training framework over time.
• Work with product and policy teams to deploy and tune moderation algorithms in production.

What it asks for

• Currently pursuing a Master's degree in computer science, machine learning or a similar field.
• Strong grounding in core machine learning and deep learning concepts.
• Experience with PyTorch or TensorFlow.
• Experience with end-to-end algorithm development: data processing, modeling and evaluation.
• Interest in content safety and the challenges of risk identification in moderation workflows.
• Familiarity with multimodal modeling (preferred).
• Hands-on experience with large model projects (preferred).
