## What does a TikTok MLE do?

Machine learning engineers are central to innovation at TikTok. They research and optimize algorithms that improve the user feed and TikTok’s ad-targeting capabilities, shaping how users interact with ByteDance’s short-form social-media app.

TikTok’s recommendation system uses a complex architecture of machine-learning techniques, including collaborative filtering, deep learning, and natural language processing (NLP). Engineers research, design, and implement these systems to optimize TikTok’s infrastructure and user experience.

TikTok ML engineers work across these teams:

- Applied Machine Learning
- App Ads and Gaming
- Business Integrity
- E-commerce Global Supply Chain and Logistics
- Risk Data Mining
- Search Ads
- Shop Ads
- Trust & Safety

These teams contain smaller internal divisions. For example, Applied Machine Learning includes subteams focused on Data, Recommendation Systems, and Innovation.

ML engineers collaborate with engineers, product managers, and data scientists to develop and optimize recommendation systems, ad ranking, and search algorithms.

The guide reports an average TikTok MLE salary of **$211,000 to $319,000 per year**, including bonus and stock. [Salary source](https://www.glassdoor.com/Salary/TikTok-Machine-Learning-Engineer-Salaries-E2230881_D_KO7,32.htm)
