Data Scientist Research

Founded in 2012, ByteDance's mission is to inspire creativity and enrich life. With a suite of more than a dozen products, including TikTok, Helo, and Resso, as well as platforms specific to the China market, including Toutiao, Douyin, and Xigua, ByteDance has made it easier and more fun for people to connect with, consume, and create content.

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.

About the role
We are looking for a highly capable and independent Data Operations Specialist to manage our machine learning labeling pipelines, the success of which would lay a solid foundation and ensure high performance of our machine learning solutions. You will be following the end-to-end delivery of various labeling projects, understanding the machine learning context and clarifying the detailed requirements, collaborating with key stakeholders to solve different types of problems that might occur during the labeling process, and providing data support to drawing deeper insights when necessary.

**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 solutions
- Act as an analytics translator, communicating complex data insights through exploratory analysis and research to discover potential bottlenecks to suggest improvement and workflow of internal teams

**Requirements**:
