Team Introduction
The AI Platform team is a team focusing on building advanced end-to-end production pipelines with core technologies including generative AI, intelligent editing and content understanding. By utilizing AI model training, optimization, deployment and applications, we provide cutting-edge AI capabilities to empower content creation and consumption on TikTok and serve billions of users.

We are looking for strong research engineers to design and develop state-of-the-art generative AI model optimization systems and solutions. The primary goal is to reduce the cost of generative AI applications while preserving quality and efficiency.

Responsibilities
- Design and develop state-of-the-art optimization framework and solutions for generative AI model training and inference, utilize techniques including but not limited to parallelism, quantization, distillation and so on.
- Research and develop cutting-edge distributed model training and inference optimization technologies, such as data parallelism, model parallelism etc.
- Communicate and collaborate with cross-functional teams to clarify model performance requirements under different use cases, make reasonable trade-offs to provide the most cost-efficient model optimization solutions to TikTok product teams to support content creation and consumption.
- Built platforms and tools that standardize common optimization methods to enlarge the usability of model optimization technologies among internal developers and researchers.Minimum Qualifications
- M.S. or Ph.D. in Computer Science or related fields with 3-5 years of experience in software development.
- Proficient in one or more programming languages, such as Python, C, or C++. Familiar with common data structures and basic algorithms.
- Deep knowledge in machine learning optimizations such as quantization, pruning, knowledge distillation, Neural Architecture Search (NAS), and optimizations for large models.
- Familiar with one or more open-source deep learning frameworks, such as PyTorch, TensorFlow, PaddlePaddle etc. Understand the underlying design of the framework, familiar with common model architectures.

Preferred Qualifications
- Experience in AutoML algorithms or model acceleration technologies.
- Experience in contributing to open-source projects is preferred.
- Ability to work collaboratively with global stakeholders
