About the Team
The success of TikTok's data business model hinges on the supply of a large volume of high
quality labeled data that will grow exponentially as our business scales up. However, the current cost of data labeling is excessively high. The Data Solutions team is built to understand data strategically at scale for all Global Business Solution (GBS) business needs. Data Solutions Team uses quantitative and qualitative data to guide and uncover insights, turning our findings
into real products to power exponential growth. Data Solutions Team responsibility includes infrastructure construction, recognition capabilities management, global labeling delivery management.

What You'll Need
- Proficiency in Python packages such as pandas, seaborn, scikit-learn, dplyr or nltk
- Distinctive communications skills and ability to communicate analytical and technical content in an easy-to-understand way to both technical and non-technical audiences.
- Intellectual curiosity, along with excellent problem-solving and quantitative skills, including the ability to disgregat issues, identify root causes and recommend solutions

Responsibilities
- Lead technical research on bridging the understanding between human and machine learning
- Build the library of elementary concepts that serve as factors to form content
- Interpretation of natural signals (image, audio, text, video) into structured computational signals for ML models to process like the human brain
- Identify patterns that indicate intentions, and verify them with experiments
- Incorporate a variety of statistical and machine learning techniques - such as logistic
regression, clustering, mixed modeling, decision trees and neural networks - on multi-modal datasets
- Understand underlying data sources and their limitations. Create innovative approaches to answer pressing questions, prepare complex data analyses and models that help solve issues,drive the scaling of automated processes and deliver significant measurable impact
- Communicate with machine learning engineers and product partners to understand business needs and provide analytical solutionsRequirements
